Digital Gauges: Frequently Asked Questions

The "OK/NG" mode on the DG-4340 sets both a "Lower value" and an "Upper value" for a single channel.
The configured relay will activate when the measured value is greater than the "Lower value" and less than the "Upper value".

In "OK/NG mode," the screen turns green when the comparator is activated and the relay is activated.
