Field measuring instruments
Friendly DMM
The 3245 SOLAR HiTESTER digital
multimeter has been developed
with an emphasis on ecological
considerations and safe design.
The photovoltaic cell charges
the lithium-ion main battery,
which exhibits superb charging
and discharging characteristics.
Should the main battery charge
become depleted, the hybrid power
system automatically switches operation to
the backup battery. So ecological considerations
are satisfied without any of the typical inconveniences
usually associated with solar-powered systems.
Also, despite its vest-pocket size, the design
conforms to CAT III (600V) and CAT IV(300V)
safety standards for use on power lines. This newstyle DMM has significant safety features and
remarkably improved operability over previous
Ecological and Safety Considerations
Despite the compact size and low price, it satisfies
CATIII (600V) and CATIV (300V) safety standards
Hybrid power system incorporates both a
solar-charged main battery and a backup
The backup battery is used only when the main battery (charged by
the solar cell) is discharged, until it is recharged by the solar cell and
switched back into operation by the hybrid power system, resulting in
both environmental friendliness and convenience.
Vest-pocket sized CATIII (600V) and CATIV
(300V) conformance
Measuring only 60 (2.4") × 145 (5.7") × 23
(0.9") mm and weighing only 140 grams
(4.9 oz), it fits easily in a pocket. Yet even at
this size, the design satisfies CAT III (600V)
and CAT IV (300V) safety standards for
industrial power line measurements.
Automatic power saving (after 30 minutes), auto and manual
range selection and a display-hold function are included.

An illumination level display of 1000 corresponds to about
50,000 lux, allowing approximate charging and usage time
Neat test probe storage on the back of
the unit
As an improvement over former models,
the test probe was separated for easier
storage and removal from the rear door that
opens 180˚, minimized projections around
the storage area.
