Cropico has developed a new test instrument compliant with new medical electrical installation requirements designed to ensure the safe condition of patient treatment suites and medical diagnostic rooms.
The updated MEIGaN guidance requires the measurement of resistance between each protective earth terminal, socket outlet or every accessible metal part and the earth reference bar in patient medical environments.
In the revised guidance a minimum test current of 1A is now permitted and the maximum acceptable resistance is 0.1W.
The new ohmmeter has been specifically developed for this type of electromedical installation testing. A special lightweight design and single push button test operation with a large direct reading display of measured values allows maximum ease of use and total portability.
It is also battery powered which means that readings can be taken without the risk of earth leakage currents from the main power supply interfering with resistance measurements.
Extended lead lengths of up to 20 m means that room sockets are all accessible from a single point and individual plug tests can be undertaken fast and effectively. The DO4002 incorporates a number of 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 4mW to 400W with respective resolutions between 1µW and 100mW.
