d. Check the low current range as follows:
1. Press
60501B:
then .
60502B:
then .
2. Wait 10 seconds then record the DMM and front panel display readings. DMM reading should be between:
60501B: 29.57mV (2.957A) and 30.43mV (3.043A).
60502B: 59.19mV (5.919A) and 60.81mV (6.081A).
3. Press
.
4. Wait 10 seconds and record the DMM and front panel display readings. DMM reading should be between:
60501B: 9.59mV (0.959A) and 10.41mV (1.041A).
60502B: 9.24mV (0.924A) and 10.76mV (1.076A).
CV Mode Test
This test verifies that the module operates in the CV Mode and that the voltage programming and readback to the front
panel display are within specifications. For each DMM reading, the corresponding front panel display should be equal to:
DMM reading ± ((DMM reading x 0.0005) + .045).
Note that if the test readings significantly disagree with the specified values or no readings can be recorded, perform the CV
MODE TEST troubleshooting procedures in Figure 3-1, in Chapter 3 of the mainframe Service Manual. If the readings are
out of tolerance, calibrate the voltage range (see Chapter 6 in the Operating Manual).
a. Connect the Electronic Load, power supply (HP6032A or equivalent), and DMM as shown in Figure 2-2. Take care in
making connections so that contact resistance voltage drop will not affect the readings.

c. Set power supply for:
60501B: 61V and 2A.
60502B: 61V and 5A.
d. Record the DMM and front panel display readings. DMM reading should be between 59.890V and 60.110V. Note that
the Electronic Load's CV annunciator is on.
