Table 4.3
Form For Recording Channel Voltage Measurements
The following table is for the customer's convenience in keeping accurate records on this unit's
performance.
If the channel voltages are measured and recorded at least two hours after the LKP system is
energized having 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 of +3 V to
30 Vdc (+3 V to 25 Vdc for LKP-12). Refer to “Magnetic Centering”, section 4.10.
Channel voltages are measured between terminals at the Metering Unit terminal block with the
LKP in service on an energized bus.
INSTRUCTIONS
1. Measure between TB1-23 and the terminal corresponding to each channel (e.g.TB1-14 for channel 1).
2. Record the channel measurements for every channel (make additional copies of this form as needed).
3. Supply the information called for below.
CHANNEL VOLTAGES
All channel voltages are taken with the negative lead on terminal TB1-23, and the positive lead
on the corresponding terminal shown below.
