[38] TEST MODE switches
The TEST MODE switches allows you to select the four test modes below. Before
changing the settings of these switches, be sure to turn the POWER switch OFF.
For details, refer to section 6.5, “Settings for Special Test Modes” (Page 6-29).
[39] RS-232C connector
This connector is used to connect a RS-232C cable. Measured values and test
results are output to an external device such as a PC or serial printer via the RS-
232C interface.
[40] STATUS OUT receptacle and switches
The output receptacle delivers a 100 VAC signal to drive an optional warning light
unit or a buzzer unit. The status signal is delivered if one of the following items is
set to ON. If two or more items are set to ON, the status signal is delivered on the
logical sum of such items.
For details, refer to section 6.4, “STATUS OUT” (Page 6-28).
• Even when the tester is operating on an AC line voltage of other than nominal 100
VAC, the signal output delivered through the STATUS OUT receptacle is 100
VAC.
[41] Power cord takeups
The four corrugated poles at the four corners on the rear panel are to take up the
power cord when the tester in not in use.
• The poles are for cable takeup and are not for legs of the tester. Never
attempt to use the poles as legs for operating the tester in the vertical posi-
tion (with its front panel faced up.). If you do, the tester will be unstable and
dangerous.
