6.1.1.2 Terminal names
Terminal No. Signal name Function I/O direction
Frame ground (connected to the casing)
• Used for connecting the shielded wire of I/O signal cables
Output of measurement condition (status)
• Turned out “H” level in the event of “Err-0”
• GO/NG judgment result output (GO)
• With the basic setup, this can be changed to strobe signal (STB) or
• measurement in-progress signal (ACK) output.
GO/NG judgment result output (+NG)
GO/NG judgment result output (-NG)
Frame ground (connected to the casing)
• Used for connecting the shielded wire of I/O signal cables
Analog voltage output
Offset input
• Can be changed to hold (HOLD) by the basic setup.
Input of trigger command of single-run measurement
• Can be changed to a trigger for continuous-run measurement or
continuous-run measurement with term specification by the basic setup.
• Input of CLEAR command, same as the key

6.1.1.3 Input/output equivalent circuit
(1) Input circuit
2.7KΩ
Input signal
(OFFS, RUN, RES)
Connected to the inside (+24V)
• Input low-level signals between 0 and 1 V. Generally drive this circuit with an open
collector-type transistor.
• Maximum current drawn from the input signal terminal is 12 mA.
