The 803250 (M-400) 100 Ampere Digital Micro-Ohmmeter is designed to measure the resistance of contacts on bussbars and breakers. The measurement is made at a high current, typically 100 amperes, using a ratiometric circuit.
This line-powered instrument employs a current regulating circuit to stabilize the test current against line voltage fluctuations and changes in the resistance of the test loop.
The use of line voltage as a power source eliminates the need to charge and maintain a heavy battery pack.
Model M-400 is compact because of its short time rating on the high-current output ranges. The meter reads directly in micro-ohms or milliohms. A three-position switch is provided so the operator can select the optimum resolution and measuring range.
