16.2 External I/O
290
Signals can be output that indicate the instrument's judgment state.
1.
Connect the GO/EXT.OUT1, NG/EXT.OUT2, and GND terminals to the device(s)
to be controlled by single wires.
See: "16.1 Connecting External Control Terminals" (

p.288)
2.
Press the SYSTEM key to open the [Environment] sheet, and move the cursor
to [GO/EXT OUT1] or [NG/EXT OUT2] .
3.
Select the conditions under which the instrument outputs a signal.
(when the
[GO/EXT OUT1] item is selected)
Select
(when the [NG/EXT OUT2] item is selected)
Select
4.
The signal for the specified state is output.
16.2.2 External Output (GO/EXT.OUT1) (NG/EXT.OUT2)
Signal Output Procedure
Measure A LOW signal is output when the judgment result is GO (pass).
Error Output a LOW level signal when an error occurs.
Busy A LOW signal is output when external start operation is disabled, such as during
startup, saving, and printing.
Trigger Output a LOW level signal while instrument is waiting for a trigger.
Measure A LOW signal is output when the judgment result is NG (fail).
Error Output a LOW level signal when an error occurs.
Busy A LOW signal is output during measurement, saving, and printing, and when it’s
finished, a HIGH signal is output.
Trigger Output a LOW level signal while instrument is waiting for a trigger.
Calibration 1 kHz output for calibrating Model 9665 10:1 Probe and the 9666 100:1 Probe.
