Calibration Procedure
VOLTAGE SENSE ADJUSTMENTS for STANDARD CURRENT MODELS
Connection:
Apply voltage at Voltage sense Input and short current source and Voltage sense negative Terminals.
And select second Range
1.
Apply to the Voltage Sense 0.000mV using a precision power supply.
2.
Hold down switch SW7 for 1 second. LED D200 will turn on to indicate that calibration has
started.
3.
Press SW7 again. LED D200 will blink while the range is being calibrated.
4.
Once D200 stops blinking and is ON, press SW7 again while still applying 0.000mV at Voltage
Sense input. LED D200 will blink while the range is being calibrated.
5.
Wait until D200 stops blinking and is ON.
6.
Apply negative 15.000 mV at Voltage Sense input.
7.
Press SW7. LED D200 will blink while the range is being calibrated.
8.
Wait until D200 stops blinking and is ON.
9.
Apply negative 150.000 mV at Voltage Sense input.
10.
Press SW7. LED D200 will blink while the range is being calibrated.
11.
Wait until D200 turns off.
12.
Now unit should display 15000 +/-2
13.
Disconnect leads.
