elem Méretek (mm): 175 x 80 x 48,5 Leírás Angol Description The UNI-T UT139A is
a new professional multimeter with True RMS classification and CAT III 600V
protection designed for the needs of electricians to measure LV distribution
networks in buildings. Innovative and industrial design with protective sleeve
ensures impact resistance of the multimeter. The instrument includes a number of
extra features such as low impedance voltage measurement (LoZ) (for variants
UT139E + UT139S), variable frequency voltage measurement (VFC) (for variants
UT139E + UT139S), contactless voltage measurement (NCV). Large and well-arranged
LCD TN backlit display ensures better display of measured values. The display
range is ą 1999. Refresh rate 2 to 3 times per second. The fuses are protected
by tube fuses (range 10A fuse FF 10A H / 600V (6 x 25mm); range mA / ľA fuse FF
200mA H / 600V (6 x 32mm)). The multimeter is powered by two AA 1.5V alkaline
batteries. The measuring range can be selected automatically or manually.
Included are test leads with spikes and batteries. UT139A is an ideal choice if
you want a professionally equipped multimeter with a number of extra features
that is also accurate, safe, easy to read and use. Product parameters
