d. Check the low current range as follows:
1. Press
6060B:
Range 6 0 Enter then CURR 6 Enter
.
6063B:
Range 1 0 Enter then CURR 1 Enter
.
2. Wait 10 seconds then record the DMM and front panel display readings. DMM reading should be between:
6060B: 59.19mV (5.919A) and 60.81mV (6.081A.)
6063B: 98.85mV (0.9885A) and 101.15mV (1.0115A.)
3. Press:
6060B:
CURR 1 Enter
.
6063B:
Range 0
.
1Enter
.
4. Wait 10 seconds and record the DMM and front panel display readings. DMM reading should be between:
6060B: 9.24mV (0.924A) and 10.76mV (1.076A).
6063B: 8.985mV (89.85A) and 11.015mV (110.15A).
CV Mode Test
This test verifies that the Electronic Load 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:
6060B: DMM reading ± ((DMM reading X 0.0005) + 0.045)
6063B: DMM reading ± ((DMM reading X 0.0010) + 0.150)
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. 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 (Agilent 6035A 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.

b. Press MODE VOLT Enter , then
6060B:
VOLT 6 0 Enter
.
6063B:
VOLT 2 4 0 Enter
.
