Field Test Interface Kit
2200
-
TESCO’s new Field Test Interface Kit (Catalog No. 2200) provides metering professionals with exceptional testing flexibility. The Field Test Interface includes a zero insertion force (ZIF) meter socket, voltage and form selection, and connection points to link it with a TESCO Field Test Kit (Catalog No. 621, 630 or GA Series). When combined with a Field Test Kit and powered via inverter (commonly used on service trucks), the Field Test Interface will then power the Field Test Kit to create a single position, stand-alone, meter accuracy testing device for various socket based meters (both mechanical & solid-state). Power for the Field Test Interface can also be supplied by customer potential via TESCO Field Test Kit (no need for the inverter).
