Number Name Function
4 Output connector 1
(OUTPUT1) The output voltage and current are
±
10 V and
±
5 mA,
respectively. This connector can be connected to a
recorder (e.g. thermal-dot recorder or data acquisition
devices) or A/D converter, which accept voltage signals
5
Output connector 2
(OUTPUT2)
The output voltage and current are
±
10 V and
±
10 mA,
respectively. The output level can be controlled from 10 V
to 1 V with OUTPUT2 level adjustment volume (18) on the
front panel.
Note: If output of current from 4 to 20 mA is required,
modification from the voltage output to the current output is
available with extra costs. For details, contact with our
sales representative.
6
Interface connector
(I/F) This connector is used to connect an amplifier unit and
case electrically. The pin layout is shown as follows. Other
than DC power voltage supply, it is possible to perform
keylock, auto-balancing, calibration value application, and
synchronous signal output. A connection cable is available
separately.

Protective grounding terminal If 3-pin power cord cannot be used for grounding, use this
terminal for grounding.
8
Power supply connector This is the connector to be connected to the AC power
cable. The AC power supply block of the amplifier unit
have a withstand voltage of 1.5 kVAC/minute against input,
output, and case.
Note: When using a power supply of 100VAC, use AC
power supply cord 47326. When using 110VAC or higher,
use optional AC power cord 200V (0311-5112). When
using 180 to 264 VAC, also use optional AC power cord
200V (0311-5112).
