2. Program the output voltage to 150V (135V for -LZ option, 115 V for –AV option) on the
low voltage range and 60 Hz (400 Hz for –AV option).
3. Use the
SELECT
key to select the Current Measurement display. Note that this is not
the Current Measurement calibration mode. Only the I RMS
LED
should be illuminated.
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.

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
