ACV measuring
• Connect the black measuring wire to the „COM"
connector, and the red one to the „V/Ω" connector.
• Set the function switch to the proper ACV setting and
connect the wires to the circuit.
Note:
• If you are unsure about the measured voltage
range, set the function switch to a high range.
• If the LCD shows „1" it means overload, and the
range should be set to a higher value.
DCA measuring
• Connect the black measuring wire to the „COM"
connector, and the red one to the „mA" connector
(max. 200mA), or connect the red wire to the „20A"
connector (max. 20A).
• Set the function switch to the proper DCA setting
and connect the wires to the circuit.
Note:
• If you are unsure about the measured voltage
range, set the function switch to a high range.
• If the LCD shows „1" it means overload, and the
range should be set to a higher value.
• Max inward current 200mA or 20A (depending
on the placement of the red wire), in case of an
exceeding current the fuse will melt.
ACA measuring
• Connect the black measuring wire to the „COM"
connector, and the red one to the „V/Ω" connector.
• Set the function switch to the proper ACA setting,
and connect the wires to the circuit.
Note:
• If you are unsure about the measured voltage
range, set the function switch to a high range.
• If the LCD shows „1" it means overload, and the
range should be set to a higher value.
• Max inward current 1000V.
Resistance measuring
• Connect the black measuring wire to the „COM"
connector and the red one to the V/Ω connector.
• Set the function switch to the proper resistance
setting and connect the wires to the measured
resistor.
Note:
• If the measured resistance value is over the
chosen max value the LCD will show „1" and
the function switch needs to be set to a higher
range. It may take a few seconds for the device to
stabilize when measuring above 1MΩ
Capacity measuring
• Connect the wire to the „V/Ω „ connector and the red
one to the „COM" connector.
• Set the function switch to a proper capacity setting
and connect the wires to the measured capacitor.
Note:
• If you are unsure about the measured capacity set
the function switch to a high range.
• If the LCD shows „1" it means overload and the
function switch needs to be set to a higher range.
• To be safe, discharge the measured capacitor
before measuring.
Diode and continuity test
• Connect the black measuring wire to the „COM"
connector, and the red one to the „V/Ω" connector
(Note: the red wire's polarity is „+")
• Set the function switch to the „
connect the wires to the measured diode.
• Connect the wires to the diode's measuring points,
if the device beeps, the resistance is lower than appr.
(70±20)Ω
Temperature measuring
• Connect the red wire to the mA, and the black
one to the "COM" connector. Touch the end of
the thermometer to the measured object and the
temperature value is displayed on the screen in
degrees Celsius.
hFE
• Set the function switch to hFE.
• Place the part into the transistor connector
depending on whether it is NPN or PNP type.
Automatic turn-off
• If the device is not used for 15 minutes it turns off
automatically. To use it again, turn the function
switch.
Background lighting
• Push the button „10" shortly to switch on or off the
background lighting.
AUTO POWER-OFF AND LCD BACKLIGHT ON
• After power on, LCD displays "APO" , mean the meter
is in automatic power off mode. With rotate the knob
in 15 minites and the figure changing. The meter is
in nonautomatic power off mode. Press "HOLD" key
to power on the meter, when "APO" isn't showing on
LCD, the meter is in nonautomatic power off mode.
Shortly press "HOLD" key to turn on/off the "HOLD"
function. Long press "HOLD" key to turn on/off the
backlight.
"HOLD" function
• Press "HOLD" key to fixed measurement value on display.
