Specifications
Interface and other functions
REMOTE
6-pin mini-DIN connector on the front panel
The optional remote controller RC01-TOS or RC02-TOS is connected to remotely
control starting/stopping of a test (note that a DIN-mini DIN adapter is required).
SIGNAL I/O
D-SUB 25-pin connector on the rear panel
For names and descriptions of connector signals, see Separate Table 3.
Input
High-level
input voltage
11 V to 5 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
Output method
Open drain output (4.5 Vdc to 30 Vdc)

ANALOG OUT
Outputs a logarithmically compressed voltage corresponding to the measured
resistance value

Rx (1 MΩ: 0.30 V, 10 MΩ: 1.04 V, 100 MΩ: 2.00 V, 1000 MΩ: 3.00 V, 10000 MΩ or
more: 4.00 V)
Output impedance: 1 kΩ
COM
Analog output-circuit common
Accuracy
± (2% of full scale)
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.
Baud rate
9600/19200/38400 bps
(data: 8 bits; parity: none; stop bit: 2 bits fixed)
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
MOMENTARY
A test is conducted only when the START switch is pressed.
FAIL MODE
Disables cancellation of FAIL judgment using a stop signal via remote control.
DOUBLE ACTION
Starts a test only when the STOP switch is pressed and the START switch is pressed
within approximately a half-second.
PASS HOLD
Allows the time of holding PASS judgment to be set to 0.2 s or HOLD.
KEYLOCK
Places the tester in a state in which no keystroke other than the START/STOP switch
is accepted.
