Portable digital microhmmeter from Cropico

With a measuring range of 600µΩ to 60Ω with 0.1 and 10mΩ resolution respectively, the lightweight DO7010 can measure with switchable current levels of 1A or 10A on all except the highest range. Externally recharged NiMh battery packs can be replaced quickly via the front panel to ensure minimum downtime anywhere.



Typical applications include measuring the bonding resistance of vehicle bodies, aircraft frames and equipment, calibration measurements and resistance measurements of electronic components and switches. In the power and utilities sectors, the DO7010 can be used for the measurement of underground cable joints and assessment of earthing and contactor resistance in substations.



An LCD panel displays full information on measurement configuration and a single start button ensures ease of use while the ability to trigger measurements by lead contact to the test device gives fast single-person operation. A remote hand terminal is also available to fully control the tester at up to 15m distance.



Other features include a robust design, true 4-terminal measurement to eliminate lead resistance errors, auto average of forward/reverse measurement and sequence testing with memory for 1000 readings.



The instrument’s data logging function also permits downloading of test sequences from a spreadsheet and uploading of test results back to the data records.



The DO7010 milliohmmeter forms part of a comprehensive range of precision measurement instruments available from Cropico Ltd, part of the Seaward Group.
