Output Floating Characteristics
Electronically balanced to allow low
output (-) terminal to float up to
2 Vpk. Common mode rejection is
typically >54 dB (500:1).
2 With both 2-wire or 4-wire configurations. When using 4-wire configuration,
lead resistance must be £ 1.5 W.
3 Full scale on the 2 MW range is 2.50 MW.
4 Load current must be £ 1 mA for specified accuracy. Output resistance is
typically <0.1 W.
