Digital Multimeter PM7 Model:W3588

PM-7
INTRODUCTION
This is a pocket type DMM with test leads accommodated all-in-one case and intended to design a thin, compact, small-sized and lightweight tester.
Adoption of low power consumption type one chip LSI and all-in-one case enables the tester to be accommodated in a chest pocket without difficulties, and to be carried in any place.
An in-circuit continuity buzzer with a measuring terminal voltage of 0.4V is provided, and a resistance switch range covers a lower power ohm.
In addition, power saving design is prepared for coping with forgetting aboutturning off a power switch.

FEATURES
The DMMs are so small that they can be put into even dress shirt pocket.
Automatic range shifting function. No replacement of battery is required.
Optimum measuring range is automatically selected to set.
Test leads can be stored in the hard case.
Since overload protection circuit is built in, the continuity, ohm and diode test
ranges are protected even if the voltage up to 250V AC/DC is impressed.
