Channel Voltage Measurements Form: LKP-80
If the channel voltages are measured and recorded at least two hours after the LKP system is
energized has been properly "centered" electrically, the information may prove valuable in the
event of any future malfunction.
It is a good idea to take an additional set of readings at the hottest time of the year, especially if
the equipment is exposed to outdoor temperatures; space is provided for the recording of three
sets of readings. NOTE: Although the channel voltages may vary widely with temperature
extremes, the accuracy will remain unaffected so long as each channel voltage falls within the
limits 70-130% of the average of all channel voltages. Maximum limits are +40 Vdc*. Refer to
“Magnetic Centering” section.
Channel voltages are measured between terminals at the Metering Unit terminal block with the
LKP in service on an energized bus.
INSTRUCTIONS
1. Record the channel measurements for every channel (make additional copies of this form as
needed).
2. Supply the information called for below.
