• 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
