FRONT PANEL CONTROLS

(Refer to Fig. 1 and 2)
1. POWER ON Switch.
2. POWER ON Pilot Light.
3. Function Switch.
Model 1655A
Five interlocking pushbutton switches which select
function and meter scale. Pressing a button releases
the previous selection. The following selections are
available:
VOLTS. Connects meter to measure voltage at
ISOLATED OUTPUT. Use 0-150 VOLTS
scales on meter. Voltage is adjustable with AC
VOLTS control.
AMPS 0 – 4. Connects meter to measure current of
ISOLATED OUTPUT. USE 0-4 AMPS scale on
meter. When voltage is set to 120 VAC, the 0-480
VA scale may be used to measure the output load
in volt-amps
AMPS 0-2. Connects meter to measure current of
ISOLATED OUTPUT. Use 0-2 AMPS scale on
meter. When voltage is set to 120VAC, the
0-240VA scale may be used to measure the
output load in volt-amps.
