PM7a | Pocket Size Digital Multimeter with Built-In Case

SanwaSKU: PM7a

Price:
Sale price$46.75


Continuity Buzzer

The buzzer sounds when the measuring object is electrically conducting.

Range Hold

The range is fixed in the measurement of varying voltage and current which is difficult to read in the auto range.

Low Power Ohm

Resistance is measured by applying voltage of approximately 0.4V or less on a measuring object.

Description

The Sanwa PM7a is a pocket-size digital multimeter with a unique foldable design.

This digital multimeter has a 4000-count display and has an accuracy of 0.7%. The device has a unique design that features an integrated protective casing that allows it to fold just like a flip phone. The device is designed to be portable and to be used for measuring weak current circuits. A similar unit is also available with integrated solar power backup (Sanwa PS8a).

The PM7a can pretty much do all the basic functions such as measuring voltage both AC (500Volts max) & DC (500 Volts max), resistance (40 mega-ohms max), continuity test with buzzer as well as diode test. It cannot however measure current.

The PM7a has a power-saving design with an auto power off feature that turns on after 15 minutes of inactivity. It consumes approximately 5mW of power and requires 2 LR44 (1.5V) coin style battery to operate.

Includes meter, instruction manual and test leads (attached).
