PREPARATION FOR USE
Preparation for use consists of checking that the rear panel line volt-
age module is set for the correct line voltage and connecting the sweep
generator to the power source. The following paragraphs provide these
procedures along with information about power requirements, warmup
times, and the operating environment.
Power
Requirements
The sweep generator accepts 115Vac
±
20% and
230Vac
±
20%, 48 to 400 Hz, single-phase power.
Power consumption is 400 VA maximum.
Line Voltage
Selection
The voltage selector drum of the rear panel line volt-
age module can be set for either 115 Vac or 230 Vac
operation (Figure 2-1). If the selector drum setting is
incorrect for the line voltage available, change it to
the correct setting as follows:
Step 1.
Remove the power cord from the line voltage module.
Step 2.
Insert the blade of a small screwdriver into the slot
at the top-center of the module, and pry open the
cover.
Step 3.
Remove the voltage selector drum by pulling it
straight out.
Step 4.
Rotate the drum so that the desired line voltage
marking faces out, then reinstall the drum.
Step 5.
Close the cover. Check that the desired line voltage
value is displayed through the opening in the cover.
Step 6.
Reinstall the power cord.
