SECTION 4 - CALIBRATION
Calibration of your analyzer is valid for 12 month periods. If any input range is uncalibrated, the analyzer
displays ‘CALIBRATION ERROR’ on power up. This may be bypassed by pressing the [↵] key.
Equipment Required:
High accuracy (0.02%) true RMS volt meter.
0-20A rms Current Generator, 120Hz
0-1000V rms Voltage Generator, 120Hz
1.000Ω precision shunt. (For < 2A rms)
0.1000Ω precision shunt. (For > 2A rms)
Equipment Connections:
IMPORTANT NOTE:
For optimum performance, always calibrate with BOTH voltage and current present simultaneously.
•
During voltage calibration, apply approximately 100mA from the same ac source to the current
channel.
•
During current calibration (including external shunt), apply approximately 5V from the same ac source
to the voltage channel.
