Introduction
This unique meter has a full complement of features in a compact package
only 3/8 inch deep and weighing less than 3 oz. The essential shirt-pocket
size meter for portability, Model PM53 is fully autoranging and has an
oversized, easy-to-read digital display. It offers the AutoTect™ feature that
guides the meter to display AC volts, DC volts or resistance based on what
you are measuring. Also offered is VolTect™, a built-in non-contact voltage
detector of AC voltages. Although very small, this meter is fully UL safety
rated to CAT III levels. The Meterman PM53 includes measurement extras
such as capacitance, frequency and continuity plus safety extras such as
transient protection to 4 kV and overload protection to either 450 V.
Safety Information
•The PM53 Digital Multimeter is certified for cULus and
EN61010-1:2001; CAT II 450 V, CAT III 300 V, class 2 and
pollution deg. 2.
•This instrument is EN61010-1 certified for Installation Category II
(450 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 450 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 > 450 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.
