Voltage source measurement test
1. Connect the 6242 and the DMM (Digital Multi-Meter) as shown in Figure 8-7
(a).
2. Set the DMM to DCV, auto range, and the Integration time 10 PLC or longer.
3. Set the 6242 to DC source mode, free run, and Integration time at 200 ms.
4. Select voltage source voltage measurement and Operate.
5. With Zero and ±F.S generated in the 300 mV range to 6 V range, verify that the
difference between the source set value and the DMM measurement value and
the difference between the 6242 measured value and the DMM measured value
are 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 6242 as outlined in Chapter 8, “CALIBRATION” or contact an
ADC CORPORATION sales representative for the calibration or servicing.
Current source measurement test (in the range between 30 µA and 300 mA)
1. Connect the 6242 and DMM as shown in Figure 8-7 (b).
2. Set DMM to DCI, auto range, and Integration time at 10 PLC or longer.
3. Set the 6242 to DC source mode, free run, and Integration time at 200 ms.
4. Select current source current measurement and Operate.
5. With Zero and ±F.S generated in the 30 µA range to 300 mA range, verify that
the difference between the source set value and the DMM measurement value
and the difference between the 6242 measured value and the DMM measured
value are 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 6242 as outlined in Chapter 8, “CALIBRATION” or contact an
ADC CORPORATION sales representative for the calibration or servicing.
