DCV 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 DCV
•
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.
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 „ " position,
•
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
Push the button „10" long to cancel the auto
•
power off function. If the inscription „APO"
appears on the display, the device does not
switch off automatically.
M
aintenanCe
Note that this device is not water-, dust- and
•
shock-resistant.
Do not use and do not store the device at high
•
temperatures, in places with high humidity or
flammability or in strong magnetic fields.
Do not use rough textile or alcohol.
•
If the device is not being used for a longer
•
time period, the battery must be taken out.
Battery replacement (1 x 9V)
If the LCD display shows „ " , the battery
needs to be replaced the following way:
Take the device out of the plastic holder and
•
take off the battery holder cover.
Take out the battery and replace it to a new
•
one. Use alkaline batteries if possible.
Put the battery holder cover back.
•
Fuse replacement
Only used the prescribed types of fuses for
•
replacing.
If the device does not operate properly,
check the following:
