6.2 ELECTRICAL PROPERTIES
Uncertainties are expressed in % of reading (R) and an offset: ± (a % R + b).
6.2.1 Voltage Inputs
Operating range: Up to 600 V
NOTE: Phase-to-neutral voltages less than 2 V and 1200 V
phase-to-phase voltages less than 3.4 V are set to zero.
Input impedance: 903 K when the device is running on battery.
Sustained overload: 660 V. Above 690 V, the device will display the OL
