4. Observe the actual output current as shown on the external DMM and current shunt.
Adjust R3 on the Range/Relay Board for a measurement display equal to the actual
output current.
CAUTION:
The amplifier wind tunnel must be covered for proper cooling if the
adjustment takes more than 1 minute.
6.4.2 Current Limit Adjustment
Note:
If the Current Limit and High Current Measurement Range Adjustments
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.
1. Adjust R50 on the Oscillator Board for an output current of 10.5 A.
