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.

Making Measurements
All measurements described in this manual use the Red test lead for
positive (+) polarity and Black test lead for Ground reference (-) unless
otherwise specified
AutoTectmode is the default function when the meter is first turned on.

AutoTectTMode
The AutoTectfeature automatically selects measurement function of
V dc, V ac, or resistance based on the input via the test leads.
●With no input, the meter displays Auto when it is ready.
●With no voltage signal but a resistance below 6 MΩis present, the
meter displays the resistance value.
●When a signal above the threshold of 1.2 V dc or 1.5 V ac up to the
rated 450 V is present, the meter displays the appropriate voltage value
in dc or ac, whichever larger in peak magnitude.
●The AutoTecttest mode input impedance is lower than most digital
multimeters and LoZ is displayed on the LCD. This may cause reading
errors if the circuit being measured is sensitive to the meter input
impedance. Input impedance is approximately 160 Ω, helping determine
if voltage is from leakage (so-called “ghost” voltages) or a hard
connection. “Ghost” voltages will be zeroed out by the low input
impedance.
●Overload-Alert Feature
When above rated 450 V is present, the meter displays OL with a
warning beep tone. Disconnect the test leads from the signal
immediately to avoid hazards.
•Range-Lock Feature
When a measurement reading is displayed in the AutoTectmode,
press the SELECT button momentarily to lock the function-range. The
LCD annunciator Auto turns off. Range-lock can speed up repetitive
measurements. Press the SELECT button momentarily again to return to
AutoTectmode.
When making resistance measurements in AutoTectmode, an unexpected
display of voltage readings alerts you that the circuit under test is still
energized.
Continuity, Audible With Symbolic Display
With Auto on the LCD, press the SELECT button once to select Continuity
function. The meter will show a symbolic open-switch display . A
continuous beep tone and a symbolic closed-switch indicates a closed
circuit. Continuity is used for checking wiring connections and operation of
switches.
Electric Field EF-Detection, VolTect
With Auto displayed on the LCD, press the SELECT button momentarily 2
times to select the EF-Detection feature. The meter displays EF. Signal
6
strength is indicated as a series of bargraph segments on the display and
variable beep tones. See the VolTectspecifications later in this manual for
a complete description of the bar graph indicators.
•Voltect
An antenna is located at the top left corner of the meter, which detects
electric field surrounding current-carrying conductors. It is ideal for
tracing live wiring connections, locating wiring breakage and to
distinguish between live or earth connections.
•Probe-Contact EF-Detection
For more precise indication of live wires, such as distinguishing
between live and ground sockets, use the V ac manual function selection
for direct contact voltage measurements.

Note
For Maximum sensitivity, hold the meter away from the VolTect
corner.

Voltage
With Auto on the LCD, press the SELECT button 3 times to select V ac
function. The meter displays LoZBVwhen it is ready.This function is
auto-ranging.
With Auto on the LCD, press the SELECT button 4 times to select V dc. The
meter displays LoZ V when it is ready. This function is auto-ranging.
Resistance
With Auto on the LCD, press the SELECT button 5 times to select resistance
function, The meter displays MΩwhen it is ready. This function is
auto-ranging.
Frequency
With Auto on the LCD, press the SELECT button 6 times to select frequency
function, The meter displays Hz when it is ready. This function is
auto-ranging.
Capacitance
With Auto on the LCD, press the SELECT button 7 times to select
capacitance function, The meter displays nF when it is ready. This function
is auto-ranging.
Return to Auto
Press the SELECT button 8 times to return to AutoTecttest mode.
Product Maintenance
Maintenance
Do not attempt to repair this meter. It contains no user serviceable parts.
Repair or servicing should only be performed by qualified personnel.
Cleaning
Periodically wipe the case with a damp cloth and mild detergent; do not use
abrasives or solvents. If the meter is not to be used for periods of longer
than 60 days, remove the battery and store it separately
