1% ... 200% In 0.5% (1% ... 200% In)
(1)
Accuracy is given by the following measurement conditions for input 2V: exclusion of errors produced by the
clamps and external voltage transformers, with a range in temperature of 5 ... 45 ºC and power factor 0 ... 1.
The 3 phase clamps L1, L2 and L3 must be of the same type. Otherwise, an
error event is logged in the EVA file; in this case measurements can be taken
with the device using the features of the L1 clamp.

(2)
Accuracy is given by the following measurement conditions for input 2V: exclusion of errors produced by the
clamps and external voltage transformers, with a range in temperature of 5 ... 45 ºC and power factor 0 ... 1.
Note: Transformers must be connected to the device with connectors and the corresponding
EEPROM in order for them to work.
