Input specifications			High-level input voltage	11 V to 15 V	All input signals are active Low controlled. The input terminal is pulled up to +12 V using a resistor. Opening the input terminal is equivalent to inputting a high-level signal.
			Low-level input voltage	0 V to 4 V
			Low-level input current	-5 mA maximum
			Input time width	5 ms minimum
Output specifications			Output method	Open collector output (4.5 V to 30 V DC)
			Output withstanding voltage	30 V DC
			Output saturation voltage	Approx. 1.1 V (at 25°C)
			Maximum output current	400 mA (TOTAL)

* 1-digit BCD active LOW input. Panel memory’s selection signal input terminal

ANALOG OUT

Outputs a logarithmically compressed voltage corresponding to the measured resistance value

RS232C

D-SUB 9-pin connector on the rear panel (compliant with EIA-232-D)
All functions other than the POWER switch and KEYLOCK function are remotely controllable

Display

7-segment LED, 4-digit voltage display, 4-digit insulation resistance display, and 3-digit time display

Memory function

A maximum of 10 types of test conditions can be stored in memory.

Backup battery life

3 years or more (at 25 °C)

TEST MODE

KEYLOCK

Places the tester in a state in which no keystroke other than the START/STOP switch is accepted.
