Resistance Tester is used to measure the ohmic value of an insulator under a direct voltage of great stability.To measure a high value resistance, techniques for measuring a low value current are used. A constant voltage source is applied to the resistance to be measured and the resulting current is read on a highly sensitive ammeter circuit that can display the resistance value.
Two types of ammeter circuits are used on our range of resistance tester, each circuit being chosen depending on the resistance values to be measured. These are compact, rugged, reliable, and easy to use. With their multiple test voltages, they are ideal for many troubleshooting, commissioning, and preventative maintenance applications.
