Meter Power-Up
NOTE:
If the meter was in Test Lock or the Test Mode timeout period had not
expired, the LCD will display the last item that was shown on the LCD at the
time power was removed.
After installing the meter into a socket and applying power, the meter should boot up and start
cycling through the Normal Display List unless:
• The meter was powered down while in Test Lock
• The Test Mode Timeout Period has not expired.
In addition to the boot-up items discussed in this section, additional settings can be configured
using iConFig.
NOTE:
If the meter was in service prior to powering down, meter and billing data is
automatically stored. During power-up, the meter retrieves the stored data.
After power is applied to the meter, the meter:
• Determines the service type
▪ Wye
▪ Delta
• Determines the phase rotation
▪ A, B, C
▪ C, B, A
• Detects any missing voltages
• Verifies the service voltages
▪ Phase-to-Neutral
o 120
o 240
o 277
▪ Phase-to-Phase
o 208
o 480
NOTE:
If the meter detects phase angle errors, the meter runs industry-standard diagnostics (see
“
Diagnostics and Alarms” below)
• Verifies the phase angles are correct for the service type (variances can be configured
with iConFig).
