Three-phase energy meter field calibrator
d) The on-site harmonic interference is too large.
4.7 Q: You can hear a "beep" sound from the instrument; but there is no display on the
screen or the display is very light, why?
A: This is caused by too weak LCD screen brightness. In the state of main interface, press
"↑, ↓" key to adjust the contrast of display screen
4.8 Q: When testing the instrument on the calibration console, the error is uncertain,
why?
A: It may be because the voltage of the calibration console is used to supply power to the
instrument, and the solution is to press F4 to choose the battery or adapter power
supply (optional).
