Three-phase energy meter field calibrator
2.4 Operating procedures for the instrument
TT
The instrument in use is operated in strict accordance with the operating procedures.
TT
Start the instrument power supply→ connect the instrument test line → connect the test line
and clip-on ammeter at the end of energy meter → set test parameters→ check→ remove the test
line at the end of energy meter →close the instrument →remove the test line at the end of the
instrument.
TT
Note: Clip-on ammeter "+" is the current input, and "-" is the current output; the middle
colors of the clip-on ammeter represent different phases: Yellow-A phase, Green-B phase,
and Red-C phase.
