Calibration procedure
1. Connect your external device to the DME7/MTX’s [GPI] connector.
2.
Select the check box of the channel numbers for which you want to perform calibration.
If you want to select all channels, select the [All Ports] check box.
3. To specify the detection range, increase the input from the external device to the maximum and click the
[Max] button; then decrease the input to the minimum and click the [Min] button.
This lets you specify the optimal detection range as appropriate for voltage drop caused by wiring or due
to the specifications of your devices.

• The threshold for on/off switching will be the center value between the maximum and
minimum input voltage values (the sum of the maximum value and minimum value, divided by
2). To prevent malfunctions, you should allow plenty of range for detection.
• If the voltage has dropped because of cable length or noise, adjust the maximum and
minimum input voltage values. Since voltage may become unstable, configure and set up
your external circuit to ensure that there is ample distance between the maximum and
minimum values.
