Output
Voltage
No voltage source is included in the MT-
1/WT3.
Line voltage is used for the energy
measurement. Therefore, the accuracy
is less than 200ppm.
Current
The current sources are designed with a
very tight feedback loop to get the most
accurate current, therefore the current
accuracy is less than 200ppm.

Voltage applied to meter
Line voltage protected by two 1 A circuit
breakers and activated only when the
meter is inserted. Voltage is also
current-limited.
