Front panel description
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
MT-1505 is fully auto-ranging and has an oversized,
easy-to-read digital display. It offers the Auto-Select feature
that guides the meter to display AC volts, DC volts or
resistance based on what you are measuring. This meter is
fully rated to CAT III levels. The meter MT-1505 includes
measurement extras such as non-contact voltage detector of
1
AC voltages, capacitance, frequency, diode and continuity plus
safety extras such as transient protection to 4 kV and overload
protection to either 600 V.
Safety Information
The MT-1505
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 (600V). 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 over-voltages may occur,
and not for primary supply lines, overhead lines and cable
systems.
Do not exceed the maximum overload limits per function
(see specifications), the limits marked on the instrument
itself. Never apply more than 600 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.
Remove test leads from circuit before opening the case.
Always measure current in series with the load – NEVER
ACROSS a voltage source.
Automatic Pocket Meter is certified for

Turning the Meter On and Off
Press the Power button for approximately 3 seconds to turn
the meter on.
To turn the meter off, press the Power button until the
display goes blank.
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
Auto-Select Mode
The Auto-Select feature 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 40Mis
present, the meter displays the resistance value, this
function is auto-ranging
When a signal above the threshold of 0.6 V dc or 1.6V ac
up to the rated 600 V is present, the meter displays the
appropriate voltage value in dc or ac, whichever larger in
peak magnitude, this function is auto-ranging
The Auto-Select test With High input impedance: 10M
which ensure the Best accuracy.
Overload-Alert Feature
When above rated 600 V is present, the meter displays OL
with a warning beep tone. Disconnect the test leads from the
signal immediately to avoid hazards.
3
Continuity & diode
With Auto on the LCD, switch to Continuity function. The meter
will show a symbol of diode display, then press the power
button momentarily 1 times to enter into continuity function with
a symbol of speaker. A continuous beep tone indicates a
closed circuit.
Continuity is used for checking wiring connections and
operation of switches.
Frequency
With Auto on the LCD, switch to frequency function, the meter
displays Hz when it is ready. This function is auto-ranging.
Capacitance
With Auto on the LCD, switch to capacitance function, the
meter displays nF when it is ready. This function is
auto-ranging.
Electric Field EF-Detection, Non-Contact Voltage
When Auto displayed on the LCD, switch to select the NCV
function. The meter displays EF. Signal strength is indicated as
a series of bar graph segments on the display and variable
beep tones. See the specifications later in this manual for a
complete description of the bar graph indicators.
An antenna is located at the top right 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.

-Contact EF-Detection
Probe
F
or 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.
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
Troubleshooting
If the instrument fails to operate, check battery, leads, and
replace battery as necessary. Double-check operating
procedure as described earlier in this manual.
