Valhalla Scientific 4165 200 mohm - 20 Kohm, Contact Resistance-Ohmmeter
Feature:
Type: Ohm Meter
Analog/Digital: Digital
Min Test Range: 200mohm
The Model 4165 and 4165-1344 have been specifically engineered to tackle the difficult application of contact resistance measurement. A detailed application note on the topic of contact resistance measurement is located at the Low Resistance Measurement Handbook Webpage.
Manufacturers and users of switches, connectors and relays are all concerned with the mating quality of the contact surfaces. The most critical test method for verifying this mating quality is the "dry" contact resistance measurement. The Valhalla 4165 and model 4165-1344 preserve the inherent "Dry" circuit status by means of an active electronic clamp across the output terminals of the built in constant current source. Each unit also offers a 2V minimum compliance mode to facilitate resistance measurement of the "non-dry" condition. The 4165-1344 also features a polarity reversal switch to allow the user to check for the presence of thermal E.M.F.s in the measurement circuit.
