NOTE 1: Other currents can also be used for High
Current calibration (20A minimum).
NOTE 2: Adjustments of R28 and R25 are
interactive. Therefore, It will be necessary to repeat
the adjustments once or twice to achieve exact
results.
The Voltage reading at E3 (shunt amplifier output)
must correspond to the current as follows: voltage at
E3 = -0.1V/A ±2%.
Examples:
40 A equals -4.00V ±0.08V
20 A equals -2.00V ±0.04V
10 A equals -1.00V ±0.02V
5 A equals -0.50V ±0.01V
