Quartzelec has equipped its engineers with DO7 units to enable them to undertake on-site resistance measurement and status checking of electric motors and generators.
Cropico's DO7 digital uohm meters have been specified for a company that makes rotating electrical machines and specialises in the repair, maintenance and service of large electric motors and generators for global customers.
Quartzelec, a electrical engineering company whose engineering operation is based at Rugby, provides a range of specialised service and support solutions for rotating plant installed in power stations, steelworks and paper mills in Europe, North Africa, the Middle East and Far East.
Now, in a move to improve after sales service and support, the company has equipped its team of electrical and mechanical service engineers with DO7 units to enable them to undertake on-site resistance measurement and status checking of electric motors and generators.
These are replacing Quartzelec's own ageing in-house testing units.
The flexibility of the in-built manual default is enabling engineers to undertake on-site multitesting of machinery very quickly.
Other benefits include high portability and a rugged design, enabling the DO7 to be carried easily from site to site and providing high impact resistance.
Ian Martin, Quartzelec's Engineering Manager, said: "We have been extremely pleased with the Cropico DO7 units since they were introduced a few months ago".
"It's a very easy to use instrument, even in the harshest of environments, producing very good testing data".
"Because of this we have now gone ahead and ordered further units for our North African operations".
Cropico DO7 digital uohm meters 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 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.
Remote start and operation is possible up to 15m, enabling hands-free use.
Built within a sealed ABS plastic case having a lid and carrying handle, the instrument offers pushbutton selectable ranges of 600mW to 60W with resolutions between 0.1 and 10mW.
Full portability is provided by mains/rechargeable battery power giving over one hour of continuous working on the lowest ranges and 20 hours of 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 counts displayed on a super-bright 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 four-wire measurement eliminating lead resistance errors.
