The Digital Meter is designed for input signals of ±10 V, ±200 V and ±20 mA processes. It can work in a temperature of Pt 100, Pt 1000, TC J, K, T and N. It has also potentimeter ranging from 100Ohm to 100KOhm. This tool is built with a resistance of 999.9Ohm, 9999Ohm, and 50.00KOhm. This device also contains a JR-P and JR 20-P models which admit many signal input types to control industrial operations. It is also designed to easily scale into required engineering units straight by frontal keys or real input signal value. This tool has a configurable decimal point for JR-P and JR 20-P 12 V to 230 V Universal AC/DC voltage supply. It also has a complete configurable which access the signal input type selection.
