The three instruments in the testo770 clamp meter family
are ideally suited for current measurement in switching
cabinets. One of the two pincer arms can be fully retracted
into the instrument. This unique grab mechanism means
that cables in tight switching cabinets can be easily
grabbed. The automatic measurement parameter detection
also ensures reliable work: in the current and voltage area,
all three instruments detect direct and alternating current
and select other parameters such as resistance, continuity,
diode and capacitance automatically.
