Digital Gauge FAQ
The comparator output for the DG-4340 has 3 channels which are comparator 1 (COMP1), comparator 2 (COMP2) and comparator 3 (COMP3). Each channel has 3 modes to select, such as [Lower] mode, [Upper] mode and [OK/NG] mode.
One determination value can be selected with the [Lower] mode or [Upper] mode. Each of [Lower] and [Upper] determination values can be selected with the [OK/NG] mode.
When the measurement value is equal to the setting value or less in the [Lower] mode, or equal to the setting value or greater in the [Upper] mode, the relay of comparator turns ON. Moreover, when the setting value [Lower] < the measurement value < the setting value [Upper] in the [OK/NG] mode, it turns ON.
