New model Cropico DO7 digital microhmmeters come with specially developed handspike test leads to add increased accuracy to the unit's rugged portable construction
New model Cropico DO7 digital microhmmeters come with specially developed handspike test leads to add increased accuracy to the unit's rugged portable construction, simplifying repeatable low resistance measurements in the workshop or field.
The new HSO series leads are robust and easy to use, with a different handgrip design than conventional handspikes allowing them to be held in any position needed for each application.
Offered with a choice of a remote start button for increased versatility and a range of lead lengths, they give accurate and long-term measurement repeatability Built within a sealed ABS plastic case having a lid and carrying handle, the instrument offers pushbutton selectable ranges of 600? ? to 60? with resolutions between 0.1? ? and 10m?.
Full portability is provided by mains/rechargeable battery power giving over 1 hour of continuous working on the lowest ranges and 20 hours' operation on all others.
The latest models also feature input protection up to 415V rms, key-protected digital calibration and a long scale length of 6000 count displayed on a daylight viewable 0.8in LED with automatic decimal point and polarity indication.
They offer 10A measuring current on the lowest ranges, plus forward and reverse measurement with an auto-averaging provision, with true 4-wire measurement eliminating lead resistance errors.
