are both adjusted, the High Current Measurement Range must be
adjusted first.

1. Connect the test equipment as shown in Figure 6-2. Use the 11.3 ohm load.

2. Program the current to 10.0 A. Program the output to 150V (135V for the -LZ option, 115

V for the –AV option) on the low voltage range and 60 Hz. (400 Hz for the –AV option).

CAUTION:

The amplifier wind tunnel must be covered for proper cooling if the
adjustment takes more than 1 minute.
