Introduction

The PM51A meter is a shirt-pocket size meter only 19 mm (.75 in) wide and weighing less than 85 g

(3 oz). With full functionality offering AC and DC voltage to 600 V, resistance to 40 MΩ, capacitance

to 300 µF, frequency to 1 MHz, continuity with beeper, and diode test. Fully autoranging, the PM51A

offers seven different measurement functions with 27 full ranges of measurement. The digital display

is oversized with large digits and icons in the display. In spite of its small size, the PM51A is full

safety rated to CAT III 300 V, CAT II 600 V, and is UL listed. No other meter offers this size with such

performance and high safety ratings.

Safety Information

• The PM51A Digital Multimeter is certified for cULus and EN61010-1:2001; CAT II 600 V, CAT III

300 V, class 2 and pollution deg. 2.

• This instrument is EN61010-1 certified for Installation Category II

(600 V). It may only be used to make measurements on energy limited circuits within equipment

and not directly connected to mains.

• This instrument is EN61010-1 certified for Installation Category III

(300 V). It is recommended for use with local level power distribution, appliances, portable

equipment, etc., where only smaller transient overvoltages may occur, and not for primary supply

lines, overhead lines and cable systems.

• Do not exceed the maximum overload limits per function (see specifications) nor the limits

marked on the instrument itself. Never apply more than 600 V between the test lead and earth

ground.

• Inspect the DMM, test leads and accessories before every use. Do not use any damaged part.

• Never ground yourself when taking measurements. Do not touch exposed circuit elements or test

probe tips.

• Do not operate the instrument in an explosive atmosphere.

• Exercise extreme caution when: measuring voltage >20 V // current >10 mA // AC power line with

inductive loads // AC power line during electrical storms // current, when the fuse blows in a

circuit with open circuit voltage > 600 V // servicing CRT equipment.

• Remove test leads from circuit before opening the case.
