Procedure D -10 Calibr ate Gigatronics 8542 P ower Meter
1
Do not connect/disconnect the power meter sensor cable with AC power applied
to the meter . Disconnection could result in destruction of the sensing element
or miscalibr ation.
Make sure the power meter POWER pushbutton is OFF .
2
Connect the power sensor cable to the SENSOR input.
3
