Last 3 pairs of 48 bits (shown in Hex) are same as unit
serial number. Check using STATUS/TIME button (e.g.
for 00-01-B3-BC-61-4E, 00-01-B3 is fixed, BC-61-4E is
the unit serial number, which is 12345678 in decimal).

Measurement Specifications
Note: Accuracy specifications include all sources of uncertainty. Except as noted, specifications
apply for the full operating range, including temperature (–10
◦
C to +50
◦
C), line voltage, input
range including specified over-range, power factor, input frequency, and drifts over a one-year
calibration interval. Specifications assume synchronization to GNSS and operation in 3-element
mode or in a well-balanced system where imbalance does not degrade accuracy.
