5.2 Checking the Tester Operation
The tester generates output only when the PROTECTION status (“PROTECTION”
is lit) is released using the interlock function. A simple operation check is per-
formed on the tester by connecting the 14-pin Amphenol plug that is supplied to the
SIGNAL I/O connector.
Carry out the procedure below to check the operation before using the tester.
• Note that, as you do this check, the tester is initialized with the initial test
setup data and consequently the previous test setup data that existed
when you turned off the POWER switch of the tester last time is lost.
1. Be sure that the POWER switch is in the OFF state.
2. Set the switches and controls on the front panel to their initial setup positions.
See Fig. 5-1.
3. Check that the Amphenol plug that is supplied is not connected to the
SIGNAL I/O connector on the rear panel of the tester.
4. Check that the power cord is correctly connected.
5. While holding down the SHIFT key, press the POWER switch.
The vacuum fl uorescent screen will start illuminating, indicating that the
power has been turned ON.
6. While holding down the SHIFT key, press the POWER switch.
After several tens of seconds, the fl uorescent display shows the version num-
ber, model name, and talk mode number.
After a few more seconds, the initial test setup data will appear.
