Milliohmmeters provide precision measurement
Digital ohmmeter range is practical for a wide range of low resistance measurement applications across the electrical, electronics, QA, instrumentation and utilities sectors
The DO4A uses true four-wire measurement to eliminate lead resistance errors across a push button selectable range from 40mW to 4kW with respective resolutions between 10mW and 1W. Contained in an aluminium case with a tilted carrying handle, the robust unit can be used in the workshop, by field or maintenance engineers or as part of more comprehensive electrical test facilities.
Input protection is provided up to 415V RMS.
For ease of operation the control functions have been kept to a minimum and a four-digit LCD gives direct readings of the resistance measured, with over-range and low-battery indicators also provided.
Other special features include an auto zero facility where thermal EMF may cause a large measuring error and warning LEDs to indicate an open circuit lead condition.
Rechargeable batteries provide full portability with over 14h of continuous working on the lowest ranges and 28h operation on others.
The Cropico DO4A is supplied ready for immediate use and comes complete with battery, mains cord and measuring leads.
In addition, a wide range of optional accessories including duplex handspikes, other specialist clips, long length leads and wire clamps further extend the instrument's versatility. Request a free brochure from Cropico....
