First Time Operation
This section contains information for new users who are unfamiliar with the
tester. After unpacking, use the following procedure to verify proper operation of
the tester.
Use the power cord supplied with the tester to connect to the local supply as
follows:
1. Connect the power cord from the rear panel to the AC supply.
The tester accepts supply voltages from 110 VAC to 240 VAC (50 Hz to
400 Hz) (refer to Appendix A:Specifications, Table A–11 on page A–11).
2. Switch the tester power on by first pressing the rear panel power switch and
then pressing the front-panel power switch. If necessary, adjust the front-pan-
el CONTRAST control to optimize the display legibility.
NOTE . When the main power switch (on the rear panel above the power
connector) is in the OFF position, the tester is disconnected from the AC power
supply.
When the main power switch is in the ON position and the front-panel power
switch is in the STANDBY position, voltage is supplied to only the reference
frequency oscillator and the front-panel STANDBY indicator (yellow LED).
When the front-panel power switch is in the ON position (green LED lighted), all
of the tester modules are supplied with operating voltage.
