On switching ‘ON’, the instrument goes through the complete self integrity check, and
display factory set ‘Warn’ and ‘Alarm’ values, before indicating ‘Ready’ for monitoring.
While in operation, the instrument monitors the work place continuously, giving the latest
updated concentration of designated gas through diffusion sampling. Suction sampling is
possible with an optional manual or battery operated and adapter. The poison resistant
pellister or long life, integrally mounted electrochemical sensors with inbuilt cross interface
filters are gas specific. Optionally the sensors can be mounted on an extension cable for
monitoring inaccessible locations before entry.
Choice of three operating modes: Normal Mode for typical confined space or area
monitoring; Bar Hole Mode for checking of bar holes when searching for underground gas
leaks; and Leak Check Mode for locating leaks in valves and piping.

Typical charge characteristics of lithium-ion. Adding full saturation at the set
voltage boosts the capacity by about 10 percent but adds stress due to high voltage.
Summary
Charging lithium-ion batteries is simpler than nickel-based systems. The charge circuit is straight
forward; voltage and current limitations are easier to accommodate than analyzing complex voltage
signatures, which change as the battery ages. The charge process can be intermittent, and Li-ion does
not need saturation as is the case with lead acid. This offers a major advantage for renewable energy
storage such as a solar panel and wind turbine, which cannot always fully charge the battery. The
absence of trickle charge further simplifies the charger. Equalizing charger, as is required with lead
acid, is not necessary with Li-ion.

15. SENSOR
What is Sensor?
A sensor is a device that measures a physical quantity and converts it
into a 'signal' which can be read by an observer or by an instrument. For
example, a mercury thermometer converts the measured temperature
into the expansion and contraction of a liquid which can be read on a
calibrated glass tube.
Figure 4: Types of sensors
16. POWER SUPPLY
The sensors must be powered with a linear regulator for
maximum precision.
Power supplies with high frequency noise, such as
switching supply circuits, can cause increased noise in the
sensor’s measured value.
Altering the power supply will require recalibration.
We recommend calibrating the sensor in its final installation,
calibrating the sensor outside with a different configuration
will yield inconsistent calibration results.
17. CALIBRATION PROCEDURE
We recommend calibrating all sensors.
The procedure differs between models.
Calibration gas is available from CO2Meter directly.
18. SERIAL FORMAT AND CONNECTION
Connection
Communication to and from the various sensors is via a
serial connection.
Pins are shown looking at the connector of the sensor.

Figure 5 & 6: Connection of sensor, example: Co-Zirconia
19. AMBIENT SENSORS
For ambient sensors we recommend an atmospheric
calibration. Fresh air is generally assumed to be at 450ppm,
but alternatively you can use 450ppm calibration gas.
This reading can be confirmed with 2,000ppm calibration
gas to check the span of the sensor, although this step is
unnecessary.
20. SENSORS USED IN ENE-001
The ENE-001 uses up to five sensors to monitor combustible
gas, oxygen (O2), carbon monoxide (CO), and hydrogen
sulfide (H2S) simultaneously.
The sensors are located inside the ENE-001 and are held in
their sockets by the flow chamber.
The sensors use different detection principles, as described
below.
21. COMBUSTIBLE GAS SENSORS
% LEL Sensor
The % LEL sensor detects combustible gas in the % LEL range.
It uses a catalytic element for detection.
The reaction of gas with oxygen on the catalyst causes a change
in the resistance of the element which affects the current flowing
through it.
The current is amplified by the ENE-001’s circuitry, converted to a
measurement of combustible gas concentration, and displayed on
the LCD.
(NOTE: The % LEL sensor can not be used in instruments that utilize
Bar Hole Mode or Leak Check Mode.)
22. LEL/PPM Sensor
The LEL/ppm combustible sensor is a specialized
version of the %LEL sensor.
It is used instead of the % LEL sensor in instruments
that are intended for use in Bar Hole Mode or Leak
Check Mode.
The LEL/ppm sensor can also be used for detection in
Normal Mode.
23. %Volume Sensor
The % volume sensor detects combustible gas in the %
volume range.
It uses a thermal conductivity (TC) element for
detection.
The presence of combustible gas cools the element
causing a change in the resistance of the element which
affects the current flowing through it.
The current is amplified by the ENE-001’s circuitry,
converted to a measurement of combustible gas
concentration, and displayed on the LCD.
24. CO and H2S Sensors
The CO and H2S sensors are electrochemical cells that
consist of two precious metal electrodes in a dilute acid
electrolyte.
A gas permeable membrane covers the sensor face and
allows gas to diffuse into the electrolyte.
The gas reacts in the sensor and produces a current
proportional to the concentration of the target gas.
The current is amplified by the Model ENE-001’s circuitry,
converted to a measurement of gas concentration, and
displayed on the LCD.
25. Oxygen Sensor
The O2 sensor is a galvanic type of sensor.
A membrane covers the cell and allows gas to diffuse
into the cell at a rate proportional to the partial pressure
of oxygen.
The oxygen reacts in the cell and produces a voltage
proportional to the concentration of oxygen.
The voltage is measured by the Model ENE-001’s
circuitry, converted to a measurement of gas
concentration, and displayed on the LCD.
Filters used: HC Filter, CO Filter, Charcoal Filter
Inlet Filter Holder : The filter holder is a clear plastic dome shaped piece on
the top of the case.
26. SENSOR FOR PM 2.5 AND PM 10
COMPARISON OF PIDS AND FIDS
Photoionization detectors (PIDs) and flame ionization detectors
(FIDs) are sensitive low-range gas and vapor instruments that are
optimized to detect different gases, typically volatile organic
compounds (VOCs).
While both can measure in parts per million (ppm), they accomplish
the measurements in different ways.
This is similar to measuring distance using a tape measure instead of
a yardstick (you get the same reading in feet using a different tool).
By better understanding the strengths and weaknesses of each
technology, the most appropriate type of monitor can be chosen for a
particular application.
In general, PIDs are smaller, lighter and simpler to use, and
therefore are preferred for portable applications, where possible.
27. HOW DO PID‘S AND FID’S WORK
A PID uses an ultraviolet (UV) light source (photo) to ionize a gas sample and detect its
concentration.
Ionization occurs when a molecule absorbs the high-energy UV light, ejecting a negatively
charged electron and forming of positively charged molecular ion.
The gas becomes electrically charged. These charged particles produce a current that is
easily measured at the sensor electrodes.
Only a small fraction of the VOC molecules are ionized.
Therefore, PID measurements are non-destructive and samples can be bagged and used
for further analysis.
An FID uses a hydrogen-air flame to ionize the sample gas and detect its concentration.
Ionization occurs when electrons are ejected from VOC molecules in the hot combustion
flame.
These ions are electrically charged and produce a current that is easily measured at the
sensor electrodes.
The VOCs in the sample stream are completely combusted.
Therefore, FIDs are destructive and effluent samples are not suitable for further analysis.
28. PID/FID COMPARISON
PID FID
Handheld, lightweight
Better at lower concentrations
0.005 (5 ppb) to 10,000 ppm (parts per million
Measures organic vapors and gases; measures some
inorganic gases
Selectivity can be increased with lower energy lamps
and decreased with higher energy lamps
Can measure directly in an inert gas matrix such as
argon or nitrogen
Non-destructive: allows sample collection with complete
sample integrity
Personnel monitoring and Fugitive emissions
Reliable, low cost, long life lamp
Intrinsically safe with cold operation
Low cost
Bulky, heavy, requires hydrogen cartridges
Good linearity throughout range
1 to 50,000 ppm
Measures organic vapors and gases; measures a few
inorganic gases
Broad sensitivity
Requires oxygen presence; for inert gas
measurements, requires dilution with air
Destructive: sample is “burned” as it is ionized
Fugitive emissions, too bulky for personnel monitoring
Frequent “flame-out” issues and hydrogen cylinder
replacement
Explosion proof using flame arrestor to isolate hot
flame; not desirable for some extremely hazardous
environments
High cost
29. LIQUID CRYSTAL DISPLAY
A digital LCD (liquid crystal display) is visible through a
clear plastic window on the front of the case.
The LCD display simultaneously shows the gas reading
for all installed sensors.
The display also shows information for each of the ENE-
001’s program modes.
30. CONTROL BUTTONS
Five control buttons are located below the LCD. They are arranged in
a circular pattern around a central button, the POWER ENTER button.
The DISPLAY (ADJ) button is on the left, the RESET SILENCE button
on the right, the ▲AIR button on the top, and the (SHIFT)▼ is on the
bottom.
Button Function(s)
POWER ENTER • turns the ENE-001 on and off.
• used during setup and calibration.
RESET SILENCE silences and resets audible alarm if the ENE-001 is programmed
for latching alarms and the alarm silence option is on 1
DISPLAY (ADJ) • activates Display Mode
• enters instructions into the ENE-001’s microprocessor
▲AIR • activates the demand-zero function (automatically adjusts the
ENE-001 in fresh-air conditions)
• scrolls through the display and settings modes
(SHIFT)▼ • scrolls through the display and settings modes
• enters instructions into the ENE-001’s microprocessor
31. Printed Circuit Boards
The ENE-001 printed circuit boards analyze, record,
control, store, and
display the information collected.
The circuit boards are located inside the case.
They are not user serviceable.
alarm LED Arrays
Four red alarm LED (light emitting diode) arrays are
visible through
frosted plastic lenses in the case.
One is on the front, one on the left side, one on the
right side, and one on the top of the case.
The alarm LED arrays alert you to gas, low battery,
and failure alarms.
32. Buzzers
Two solid-state electronic buzzers are located inside the case.
Two
holes on the bottom front of the case allow the sound to exit
the case.
The buzzers sound for gas alarms, malfunctions, low battery
voltage,
and as an indicator during use of the ENE-001’s many display
and
adjustment options.
Vibrator
A vibrating motor inside the ENE-001 case vibrates for gas
alarms,
unit malfunctions, low battery voltage, and as an indicator
during
normal use of the various modes of the ENE-001.
33. INFRARED COMMUNICATION PORT
(OPTIONAL)
An infrared (IR) communications port is located on the lower right
side of the ENE-001.
The data transmitted through the port is in standard IrDA protocol.
A computer’s infrared port or an IrDA/serial or IrDA/USB cable
connected to a computer’s serial port can be used to download data
saved by the ENE-001 to a computer using the ENE-001 Downloading
Software. See the downloading software operator’s manual for data
logging and downloading instructions.
34. BATTERIES
Three AA-size alkaline batteries (standard) or an optional rechargeable Ni-MH
battery pack (3.6 VDC) power the ENE-001.
Instrument run time is dependent upon battery type.
At 25°C the alkaline batteries last up to 14 hours and the Ni-MH battery pack
lasts up to 16 hours.
The battery icon in the lower right of the LCD shows remaining battery life.
If a Ni-MH battery pack is installed in the ENE-001, an “N” appears to the right
of the battery icon.
When the ENE-001 detects low battery voltage, a low battery warning is
activated.
When battery voltage is too low for normal operation, the ENE-001 sounds a
dead battery alarm.
The alkaline batteries or Ni-MH pack can be replaced by removing the battery
cover on the back of the case.
Turn the battery cover release knob counterclockwise to release the cover.
The Ni-MH battery pack can be recharged by placing the ENE-001 in its
optional battery charging station or by placing the battery pack in the charging
station.
35. Pump
A diaphragm pump inside the ENE-001 draws the sample to
the sensors.
It can draw sample from as far as 40 feet from the ENE-001.
The pump is not user serviceable.
CAUTION: Sample hose lengths of more than 40 feet are
not recommended for the ENE-001 because of flow rate
reduction.
Flow Chamber
The flow chamber is on the back of the ENE-001 and is held
in place by three phillips screws. The flow chamber seals on
the face of the
sensors inside the ENE-001 and routes flow from the pump
to the sensors to the exhaust port (also a part of the flow
chamber).
The flow chamber includes filter ports for the HC filter and
the CO filter.
36. WHAT’S A BETTER SAMPLING METHODOLOGY
FOR A TOXIC GAS DETECTION SYSTEM?
Definitions
There are two prominent sampling methods
used in gas detection: Sample draw and pass
-ive diffusion.
A sample draw system uses a pump to draw sample back into the
instrument, where it enters the sensor for analysis, and is then
exhausted to the atmosphere or vent line.
Gas detection instruments with passive diffusion sensors do not use a
pump to pull the sample to the sensor. Instead, they rely on the inherent
movement of the air to direct a sample to them. In portable/survey
applications, the sensors are usually located integral to the analyzer
enclosure, but can also be deployed remotely on an umbilical electrical
line.
In multi-point systems, they are mounted remotely in the field, and
connected electrically to the analyzer control panel, or SCADA
(Supervisory Control and Data Acquisition) system. In some cases,
wireless communication can be used.
