A Portable Solution For Low Resistance Measurement

The Cropico 4000 digital ohmmeter range from Seaward provides a highly practical solution for a range of low resistance measurement applications in the automotive manufacturing and engineering sector

by Ian Watson | Thursday 7 April 2011

The portable and rugged instrument includes a number of advanced features to ensure measurement accuracy including forward and reverse current measurement with auto averaging, true current zero, long scale length and a selectable measurement range from 40m ohms to 4k ohms.

Within the range, model 4001 also includes temperature compensation, with preset coefficients for copper and aluminium plus user settable coefficients for other materials. Temperature measurement over the range –50 to +800ºC is also available.

Protection up to 415V rms is provided at the measurement terminals and push button operation is achieved easily by clearly marked function controls. Direct reading measured values are displayed on a four-digit LCD display.

Over range and low battery indication is also provided and warning LEDs illuminate when an open circuit lead condition is detected.

The Cropico 4000 series comes complete with a standard 1 metre length lead set and a rechargeable battery option includes a battery pack, docking station and charger.

The 4000 Series of milliohmmeters forms part of a comprehensive range of precision measurement and electrical safety testing instrumentation from the Seaward Group.
