Digital Gauge Frequently Asked Questions

The DG-4340 comparator output has three channels: Comparator 1 (COMP1), Comparator 2 (COMP2), and Comparator 3 (COMP3). For each channel, you can set the "Lower" mode, "Upper" mode, and "OK/NG" mode.

In "Lower" mode, a single judgment value is set, in "Upper" mode, a single judgment value is set, and in "OK/NG" mode, two judgment values, "Lower" and "Upper", are set.

In "Lower" mode, the relay turns ON when the measured value is below the set value (the screen lights up red), and in "Upper" mode, the relay turns ON when the measured value is above the set value (the screen lights up red). In "OK/NG" mode, the relay turns ON when the measured value is between the "Lower set value" and the "Upper" set value (the screen lights up green).
