These boards are designed for maximum throughput andoperator efficiency to perform a watt-hour accuracy test. A com-mon application is as a retirement test board or an acceptancetest board during a large scale meter exchange project (e.g. AMIdeployment). Each board can be custom designed to suit yourindividual requirements. Test results are exported from the boardin a .CSV file and can be automatically uploaded to your meterrecords system or stored in a TESCO meter records module.Meter Socket Positions: Up to 96 pneumatic socket positions.Most common configurations are 4 and 8 position.Operation• Operator loads meters into a bank of sockets – an indicatorlight confirms properly seated meters• Operator scans barcodes on meters and sockets to set up theboard and capture meter information. If this is a retirementtest, the operator then takes photo of last dial locations onmeter with same handheld bar code scanner.• After scanning, test automatically begins.• Operator loads second bank, while first is testing.• Cycle time is better than 2 meters per minute but ultimatelydepends on the number of sockets and the type of meters.MULTI-POSITION WATT-HOURTEST BOARD

Phase sequence is simply indicated by two neonlights. One light is for phase sequence 1-2-3 and the other light isfor phase sequence 3-2-1.Where the voltages are symmetrical and equal, one light willalways be out. When testing unsymmetrical voltages (such as twophase wires and the neutral of a Y system) one light will be brightand the other dim; the phase sequence will then be that indicatedby the brighter light.The TESCO Phase Sequence Indicator can be used on polyphasevoltages from 115V to 600V, at 60 cycles. The instrument iscompletely self-contained, and does not require a range-changingswitch. There are no moving parts, and the two leads are perma-nently attached to the body. The three electrodes are conspicuouslynumbered, to facilitate phase identification.The instrument is extremely easy to use. The lead with the clip (#2)is attached to one phase terminal. The insulated prod (#1) is thentouched to the second phase terminal and the prod (#3) on theend of the instrument body is touched to the third phase wire: thepositions of the prods can be quickly interchanged to reverse theindication.The body of the instrument is made of insulating material andmeasures 1 inch (2.54 cm.) in diameter and 6 3/8 inches (16.17cm) long overall. The total weight including leads is four ounces(.114 kilos), making it extremely convenient to pack for every job.Catalog No. 500TESCO Phase Sequence IndicatorPHASE SEQUENCE INDICATORCATALOG NO. 500

In operation, the two leads carrying the testcurrent are connected to one of the transformer windings. Theother two leads from the indicating meter are connected to theother winding.When the push button is depressed, DC current from a small drycell flows through the transformer winding. Themomentary induced voltage in the other winding causes thecenter-zero milliammeter to deflect in one direction. When thepush button is released, the reverse induced voltage causes an op-posite deflection.The leads with the polarity marks are attached to the transformerterminals having polarity marks. If the latter are correct, themeter will deflect to the right when the button is depressed, tothe left when it is released. Incorrect polarity will cause the meterdeflections to be the reverse of the above.The polarity checker can be used on all types of transformersthrough a great range of sizes. It will operate equally well on smallelectronic and instrument transformers, metering transformers,both potential and current, and large power transformers. A sensi-tivity control adjusts the current to suit the size of the transformerto be checked.In addition to checking the polarity of a single transformer byitself, this device can be used to check out the correctness of thewiring in a transformer rated meter installation.To use the polarity checker for this purpose, connect the test cur-rent leads to the isolated primary of one of the instrument trans-formers, either potential or current. The indicating meter leads arethen connected to various terminals on the test switch or meter.The small panel meter requires no calibration, and the size D drycell is easily and quickly replaced.Specifications• Power: one D size dry cell• Size: 3 ¾” x 6 ¼” x 2 ¾”• Weight: 1 lb. 11 oz.Accessories• Carrying Case, Catalog No. 901TRANSFORMER POLARITY CHECKERCATALOG NO. 865

If for any reason the groundconnection has a resistance, this can be immediately detected bythe Test Set.The instrument consists essentially of a voltmeter which can beshunted by a resistance of 60 ohms. The voltmeter is of the sup-pressed zero type with a double range, from 65 to 130 or from 130to 260, and can be used for checking service voltage independentlyof the ground test.When making the ground test, connect one lead to a live 120V legof the service and the other lead to the ground connection. De-press the range button marked “130 V.” The voltmeter will indicatethe prevailing voltage. Then depress the button marked “GroundTest.” Two amperes will now ow through the shunt resistor and theground return. If the resistance of the ground is zero, then thereshould be no change in the reading of the voltmeter. But if theground connection has measurable resistance, then part of the IRdrop will be across the ground, leaving less across the shunt resis-tor, and the reading of the voltmeter will drop.The suppressed zero magnifies the visible effect of the voltage drop and also facilitates reading of the actual voltage on a smallmeter of this type. Scale divisions are in increments of two volts in terms of the low range, four volts on the high range. To as-sist in making a rapid check of the condition of the ground, the voltmeter scale is divided into colored sectors as follows... • Red 65 to 86 Volts • Yellow 86 to 106 Volts • Green 106 to 130 VoltsThe 86 and 106 volt points correspond, respectively, to ground resistance of 24 and 8 ohms. In addition to checking servicegrounds, the Test Set can be used to check the condition of potential transformers on transformer rated metering installations.The current drain at 120 volts is 2 amperes, which will place a burden of 240 voltamperes on the secondary of the potentialtransformer. Any excessive deflection of the voltmeter will then indicate a condition requiring further investigation.Specifications• Size: 6 ½” x 4 1/8” x 2 5/8”• Weight: 1 lb. 6 oz.SERVICE GROUND TEST SETCATALOG NO. 900Accessories• Carrying Case, Catalog No. 901
