This
is a brand new DT-9939  certified
industrial true RMS digital multimeter from Ruby Electronics.
DT-9939 provides safe measurements with double molded plastic housing
design and IP67 waterproof function. DT-9939 performs datalogger &
True RMS AC voltage and current measurements, 40,000 counts resolution
and a 0.06% basic DC accuracy. The large LCD display with analog
bargraph and backlit ensure that readings are easy to read under all
circumstances. All inputs are protected to EN 610101-1 CATIV 600V/CATIII
1000V.
This
device with the included software allows the data to be stored and
recalled wirelessly to/from a Windows PC. Proper use and care of
this meter will provide many years of reliable services.
Safety
Conformance: EN61010-1 CAT IV 600V, CAT III 1000V 1000V input protection
on all ranges 10A/1000V & 0.5A/1000V fuses
