Meter Shop Testing Test Equipment
Meter shops develop testing configurations specific to their own needs. The
following is a list of standard test equipment that can be useful when testing a
REX meter:
■ stable mounting assembly for the REX meter to be temporarily installed
to ensure proper orientation and allow the necessary voltage and
current connections to be made
■ reliable power supply with at least the following characteristics:
■ provides voltage source for energizing the meter at its rated voltage
■ provides unity power factor
■ supplies lagging power factor of 60 ° for 0.5 PF testing
■ reference Wh standard
■ phantom load device or other loading circuit that has the current
capacity ranges suitable for the desired test amperes
■ control equipment for counting and timing the pulse output
■ precision voltage and current transformers
■ voltmeters, ammeters, phase angle meters, power factor meters, and
any other measuring equipment
■ at least one of the following:
■ an infrared pick-up head for detecting the K
h
pulses of the test LED
(recommended)
■ a reflective pick-up assembly for detecting the pulse indicators on
the meter LCD
