To avoid possible electric shock or personal injury, follow
these guidelines:
•
Protect yourself against electric shock.
•
Avoid any misuse or improper usage to protect the
device from any damage.
•
Before measuring current, check the Meter's accessori-
es (fuses, probes), ensure the good working condition,
to avoid any damage. Do not use the device with da-
maged test leads.
•
Do not use the Meter around devices with high electri-
city and frequency which can generate interference,
due to avoid misuse, false measurement, damage or
immeasurable values on the screen.
•
Use the device only according to the guidlines and for
appropriate measurements. If you misuse the Meter, it
cannot work properly in the future.
•
Do not operate the Meter around explosive gas, vapor,
or dust.
•
Check the device before every usage, verify the Meter's
operation in the selected position and ensure the con-
nection of the test leads.
•
If you do not know the range what you want to mea-
sure, set up the switch to the highest measuring value
and go backwards until it achieves the appropriate
range.
•
To avoid any damage, do not use the device for measu-
ring more than the rated input voltage.
•
Use caution when working with voltages above 60V dc,
or 30V ac. These voltages pose a shock hazard.
•
When using the probes, keep the fingers behind the
finger guards.
•
Before rotating the range switch to select functions,
disconnect test leads from the circuit under test.
•
To avoid possible damage to the Meter or to the equip-
ment under test, disconnect circuit power and dischar-
ge all high-voltage capacitors before testing diodes,
continuity or resistance.
•
Before measuring current turn OFF power to the circuit
before connecting the Meter to the circuit.
•
Replace the batteries as soon as the battery indicator
appears on the screen.
•
Disconnect test leads before opening the case or the
battery door.
•
Do not use the Meter if it operates abnormally.
•
If the product is not in use, remove the battery and
store the Meter in a cool, dry place, and do not store in
highly humid environment.
•
To avoid fire, or any damage, replace fuses only with
the specified ratings: F 200mA/250V, F 10A/250V.
•
Do not use the device if the back battery cover is open
or does not fit closed and fixed properly.

Power button
Press the power button once to turn the device on or off.
button
Backlight turn on/off. Pressing this button, the backlight can
be turned on and will remain on until another press. Basi-
cally, the backlight function is automatic, the device detects
the lights around its environment and gradually selects the
brightness. By pressing the button, the backlight can be tur-
ned on to the maximum brightness.
Warning: Because of energy-saving, the automatic backlight
function cannot work with low powered battery.

Voltage Measurements
Turn the rotary switch to V
ge) mode.
Connect the black test lead to the „COM" terminal, and the
red test lead to the "V" terminal.
Connect the probes to the desired test points of the circuit
and measure the voltage.
Read the measured voltage on the display. The polarity of
the red test lead will be displayed on the screen (only the
negative).
Warning: If you do not know the range what you want to
measure, set up the switch to the highest measuring value.
To avoid electric shock or any damage, never operate the
Meter more than 500V DC or 500V AC RMS voltage.
