A digital multimeter (DMM) is an electronic instrument that measures voltage, current, and resistance. A DMM displays measurements digitally and can measure AC and DC voltage, AC and DC current, and resistance. It may also have features to measure frequency, temperature, capacitance, continuity, and diode performance. A DMM uses symbols on its front panel to indicate the measurement units. DMM specifications include the number of display digits, measurement accuracy, and voltage/current ranges and resolutions. DMMs are used to troubleshoot circuits by measuring voltage, current, and resistance. True RMS DMMs provide accurate measurements of non-sinusoidal waveforms.

6. Understanding DMM Display Specs
Display is specified as Digits or as Count
20,000 count
• Digits: 3 1/2, 4 1/2, etc.
– Example: 3 1/2: (read as three and half digit DMM)
– starting from the least significant digit (right most), 3 “full” digits
from 0-9
– Left most digit - 1 “half” digit (can read less than 9). Ex: 1999
• Count: 3200, 4000, etc...
– 4000 count display reads from 0-3999
– 3200 count display reads from 0-3199
http://www.fluke.com/fluke/inen/products/Digital-Multimeters.htm
6 Digital Multimeter Basics DMMBASE1.PPT
7. Understanding DMM Accuracy Specs
Accuracy is specified in percentage %
• Closeness with which an instrument reading approaches the true value being measured;
or largest allowable error.
• Percentage of reading (digital multi-meters) vs. percentage of scale or range (analog meters):
Example: 1%scale vs. 1% reading
% scale: If scale or range is 1000V, an accuracy of 1% is equal to +/- 10V. 120V reading
could = 110-130V.
% reading: 1% accuracy with 120V reading= 118.8-121.2V.
• Least significant digit unstable:
Example: Accuracy spec = +/-(1%+2)
Reading of 200.0mV= 197.8 - 202.2mV

8. Understanding DMM Specs
Range and Resolution
• Resolution is the smallest change in measured value to which the instrument will respond.
• As the range increases, the resolution decreases:
Range: Resolution:
400.0mV .1mV (=1/10 mV)
4.000V .001V (=1mV)
40.00V .01V (=10mV)
400.0V 0.1V (=100mV)
1000V 1V (=1000mV)
• For maximum resolution, choose the lowest possible range.

9. Measurements using Multimeter
• Measuring voltage –
Testing for proper supply voltage is usually the first step when troubleshooting a
circuit.
How to make voltage measurements :
• Select V~ (ac) or V (dc), as desired.
• Plug the black test probe into the COM input jack. Plug the red test
probe into the V input jack.
• If the DMM has manual ranging only, select the highest range so as
not to overload the input.
• Touch the probe tips to the circuit across a load or power source (in
parallel to the circuit).
• View the reading, being sure to note the unit of measurement.
http://www.fluke.com/fluke/inen/products/Digital-Multimeters.htm
10. Measurements using Multimeter
• Resistance Measurement –
Most DMMs measure down to 0.1Ω, and some measure as high as 300 MΩ (300,000,000 ohms).
Infinite resistance (open circuit) is read as“OL” on the meter display.
How to make resistance measurements:
• Turn off power to the circuit.
• Select resistance (Ω).
• Plug the black test probe into the COM input jack. Plug the red test probe
into the Ω input jack.
• Connect the probe tips across the component or portion of the circuit for
which you want to determine resistance.
• View the reading, being sure to note the unit of measurement– ohms (Ω),
kilohms(kΩ), or megohms (MΩ).
http://www.fluke.com/fluke/inen/products/Digital-Multimeters.htm
11. Measurements using Multimeter
• DC and AC current –
Current measurements taken with the DMM alone require placing the meter in series with the
circuit being measured. This means opening the circuit and using the DMM test leads to complete
the circuit.
How to make current measurements
• Turn off power to the circuit.
• Cut or unsolder the circuit, creating a place where the meter probes can be inserted.
• Select A~ (ac) or A (dc) as desired.
• Plug the black test probe into the COM input jack. Plug the red test probe into the
amp or milliamp input jack, depending on the expected value of the reading.
• Connect the probe tips to the circuit across the break so that all current will flow
through the DMM (a series connection).
• Turn the circuit power back on.
• View the reading, being sure to note the unit of measurement.

12. True-rms vs. Average-sensing
What does “rms” mean
• RMS is the Root Mean Square or effective heating value of any ac
voltage or current waveform.
• RMS is the equivalent DC heating value of an AC waveform.
Power consumed in R1 is same for both AC and DC source
if the VacRMS = Vdc.
http://www.fluke.com/fluke/inen/products/Digital-Multimeters.htm
12 Digital Multimeter Basics DMMBASE1.PPT
13. True-rms vs. Average-sensing
Average-sensing works for a perfect sinewave
• An average-sensing meter assumes a non-distorted sine wave
and does the following calculation:
• RMS value = 1.11 X Average value
http://www.fluke.com/fluke/inen/products/Digital-Multimeters.htm
13 Digital Multimeter Basics DMMBASE1.PPT
14. True-rms vs. Average-sensing
What if the waveform is non-sinusoidal?
• For this current waveform, the effective or True-rms value = 1.85 x
Average value.
• An average-sensing meter’s reading (1.11 x Average) would be 40
% too low.
http://www.fluke.com/fluke/inen/products/Digital-Multimeters.htm
14 Digital Multimeter Basics DMMBASE1.PPT
15. True-rms vs. Average-sensing
What if the waveform is non-sinusoidal?
• Average-sensing meters typically measure RMS high for voltage and low for
current where there is waveform distortion.
• True-rms meter or clamp accurately measures both distorted waveforms and
sine waves.
Multimeter Type Average True RMS
Response to
sine wave Correct Correct
Response to
square wave 10% High Correct
Response to single
phase diode rectifier 40% low Correct
Response to 3
phase diode rectifier 5-30% low Correct
http://www.fluke.com/fluke/inen/products/Digital-Multimeters.htm
15 Digital Multimeter Basics DMMBASE1.PPT
16. True-rms vs. Average-sensing
What is Crest Factor?
• Crest Factor = Peak / RMS
• For ideal sine wave, CF = 1.414
http://www.fluke.com/fluke/inen/products/Digital-Multimeters.htm
16 Digital Multimeter Basics DMMBASE1.PPT
17. True-rms vs. Average-sensing
What is Crest Factor?
• For this current waveform, Crest Factor = 2.9
17 Digital Multimeter Basics DMMBASE1.PPT
18. True-rms vs. Average-sensing
Crest Factor is an indication of harmonics
• For current measurement, the higher the CF, the greater the
waveform distortion.
• CF spec important for current clamp, since current distortion
is typically higher than voltage distortion.
C.F. = 1.43 C.F. = 2.39 C.F. = 4.68
18 Digital Multimeter Basics DMMBASE1.PPT
19. True-rms vs. Average-sensing
Summary
Minimum specifications for measurements
on electrical power systems:
• True RMS
– Accurate for both linear and non-linear loads
• Crest Factor 3
– Accurate for current waveforms with CF not exceeding 3
– CF=3 at max range; CF=6 at half-range
• IEC 1010-1 CAT III-600 V
– Distribution level: power distribution equipment.
