6253 DC Voltage Current Source/Monitor Operation Manual
6.3 Test Method
6-2
Voltage source and measurement test
1. Connect the 6253 and a DMM (digital multimeter) as shown in Figure 7-1 (a).
2. Set the DMM to DCV, auto range and integration time of 10 PLC or longer.
3. Set the 6253 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 100 V range,
verify that the differences between the source values and the DMM measured
values and between the 6253 measured values and the DMM measured values are
within the accuracies described in Chapter 8, “SPECIFICATIONS.”
NOTE: If the result of this test does not fall within the accuracy
specifications, calibrate the 6253 as outlined in Chapter 7,
“CALIBRATION” or contact an ADC CORPORATION sales
representative for the calibration or servicing.
Current source and measurement test (from 3 A to 300 mA)
1. Connect the 6253 and a DMM as shown in Figure 7-1 (b).
2. Set the DMM to DCI, auto range and integration time of 10 PLC or longer.
3. Set the 6253 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 from the 3 A range to 300 mA range,
verify that the differences between the source values and the DMM measured
values and between the 6253 measured values and the DMM measured values are
within the accuracies described in Chapter 8, “SPECIFICATIONS.”
NOTE: If the result of this test does not fall within the accuracy
specifications, calibrate the 6253 as outlined in Chapter 7,
“CALIBRATION” or contact an ADC CORPORATION sales
representative for the calibration or servicing.
