2.2 Test Connection
Below example for calibration of a micro-ohmmeter using the 200 μΩ range (200 A max).
The P1 connection can step through the set points, with P2 to common zero point.
2.3 Operating Precautions
If thermal emfs are suspected the voltage terminal output should be checked on all positions
with zero current flowing (current leads disconnected).
The zero position is checked with the voltage potential leads from the unit being calibrated,
connected together on the 5070’s ‘0’ voltage terminal.
