6240B DC Voltage Current Source/Monitor Operation Manual
7.3 Test Method
7-2
Voltage source and measurement test
1. Connect the 6240B and a DMM (Digital Multi-Meter) as shown in Figure 8-1 (a).
2. Set the DMM to DCV, auto range and integration time of 10 PLC or longer.
3. Set the 6240B to DC source mode, AUTO trigger and integration time of 200 ms.
4. Select voltage source voltage measurement, and set the output to Operate.
5. With ZERO and Full Scale generated in the 300 mV range to 15 V range, verify
that the difference between the source value and the DMM measured value is
within the accuracy described in Chapter 9., "SPECIFICATIONS."
NOTE: If the result of this test does not fall within the accuracy specifications, cali-
brate the 6240B as outlined in Chapter 8., "CALIBRATION" or contact an
ADC CORPORATION sales representative for the calibration or servicing.
Current source and measurement test (30 µA to 1 A range)
1. Connect the 6240B and a DMM as shown in Figure 8-1 (b).
2. Set the DMM to DCI, auto range and integration time of 10 PLC or longer.
3. Set the 6240B to DC source mode, AUTO trigger and integration time of 200 ms.
4. Select current source current measurement, and set the output to Operate.
5. With ZERO and Full Scale generated in the 30 A to 1 A range, verify that the
difference between the source value and the DMM measured value is within the
accuracy described in Chapter 9., "SPECIFICATIONS."
NOTE: If the result of this test does not fall within the accuracy specifications, cali-
brate the 6240B as outlined in Chapter 8., "CALIBRATION" or contact an
ADC CORPORATION sales representative for the calibration or servicing.
