Introduction
This unique meter has a full complement of features in a package only 3/8
inch thick, weighing less than 3 oz. for the utmost in shirt-pocket
portability. The PM55 is fully autoranging and has an oversized, easy-toread digital display. With an AutoTect™ feature that enables the meter to
detect and display measurements of AC Volts, DC Volts and Resistance. The
PM55 offers VolTect™, a built-in non-contact voltage detection of AC
voltage. Although very small, this meter is fully UL safety rated to CAT III
levels and is UL listed. The Meterman PM55 precision meter includes
measurement extras such as capacitance, frequency, DC microamps and
safety extras such as transient protection to 4 kV and overload protection to
600 V.
Safety Information
• The PM55 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.
• Always measure current in series with the load – NEVER ACROSS a
voltage source.
