Portable, programmable micro-ohmmeter

Compact bench-top unit can be used for a number of tasks including cable resistance measurement, contact resistance measurement of connectors, switches, relays and similar components

Precision instrument specialist H Tinsley has introduced a new programmable micro-ohmmeter, the 5891 The compact bench-top unit can be used for a number of tasks including cable resistance measurement, contact resistance measurement of connectors, switches, relays and similar components in accordance with standards, inductive resistance measurement in transformer and electric motor windings, and the measurement of thermistors and other heat-sensitive components

In addition it can perform ground continuity and metallic coating measurements.

Operating from mains supply or optional rechargeable batteries the unit provides four-wire resistance measurement from 0.1 microOhms to 200 kOhms with an accuracy of 0.03 percent and resolution to 0.1microOhms.

Measurement current is 10 microA to 10A with a choice of three current values for each range, and there is a temperature compensation option for display of the measured resistance value relative to 20C for copper or aluminium.

Up to 1000 measurements can be stored together with their average, minimum and maximum values.

Other standard features include programmable analogue output, programmable limits and an RS232 interface, with IEEE 488 interface optional.
