Usage
•
Check the 9V battery and press the POWER
button. If the battery is depleted, the battery
symbol appears on the screen.
•
The signs near the connectors warn about not
exceeding the inward voltage or current. This is
to prevent damage to the inside circuits.
•
Before measuring set the function switch to the
desired position.
•
If you are unsure about the magnitude of the
result, set the switch to the highest possible
range and go backwards until you reach the
correct setting.
DC and AC voltage measuring
•
Connect the black measuring wire to the „COM”,
and the red one to the „V/ W /Hz” connector.
•
Set the function switch to the correct V position
and connect the wires to the voltage source
paralelly.
Note:
•
If you are unsure about the magnitude of the result, set the
switch to the highest possible range and go backwards until you
reach the correct setting.
•
set the DC / AC switch to the desired (DC or AC) function.
•
If only an „OL” is displayed on the screen, it signals overload.
switch to a higher range.
•
Do not connect voltage exceeding DC 1000 V / AC 700 V to the
connectors. Results may be displayed at higher voltages also, but
this may lead to damage to the inside circuits.
•
Do not touch the high voltage circuits while measuring.
DC and AC current measuring
•
Connect the black wire to the „COM” and the
red one to the „mA” connector (max. 200 mA)
or the „20A” connector for measuring 200 mA
or 20A.
•
Set the function switch to the proper range.
•
Connect the the wires to the circuit serially.
•
For measuring current between 200 mA and
20A follow the instructions above, but connect
the red wire to the „20A” connector.
Note:
•
If you are unsure about the magnitude of the result,
set the switch to the highest possible range and go
backwards until you reach the correct setting.
•
If only an „OL” is displayed on the screen, it signals
overload. switch to a higher range.
•
The maximum inward current is 200 mA or 20 A
depending on the connector. (For maximum 15
seconds.)Too much currency overheats the fuse which
needs to be replaced. The 20 A measuring range is not
protected.
•
Maximum overload voltage: 200 mV.
Resistance measuring
•
Connect the black wire to the „COM”, and the red
one to the „V / W / Ω” connector.
•
Set the function switch to the desired resistance
range.
•
Touch the wires to the measured circuit paralelly.
Warning: make sure that the measured circuit is
not under power!
•
The maximum overload capability for the
connector is 250 V RMS (for maximum 10
seconds).
Note:
•
If the measured resistance value is over the maximum
threshold and the device signals overload („OL”), select a
higher range. When measuring above 1 MW it may take a
few seconds for the device to stabilize the displayed value.
This is completely normal for such resistors.
•
If you do not connect a resistor to the connector (or there is
a break) the display will show „OL”.
•
If you are measuring a resistor that is part of a circuit make
sure that the circuit is not under power and all capacitors are
discharged.
•
Do not connect inward voltage to the device as it may lead
to damage to the inside circuits.
•
The outward voltage on connectors not under power is
approximately 3 V.
Capacity measuring
•
Set the function switch to F position.
•
Connect the measured capacitor to the
CX connector. Pay attention to the correct
polarity.
Note:
•
If the measured value exceeds the maximum value of the
selected range and the device signals overload („OL”),
select a higher range.
•
Unit: 1 nF=10-3 μF vagy 1000 pF
•
Do not connect external voltage or current to the
connector! Turn off the power and discharge the capacitors
before measuring. Also discharge the electrolyte
capacitors before measuring!
•
Before measuring discharge the electrolyte capacitors
more times. (Close the capacitor to 10-20 seconds and V
measure the capacitor if it is discharged.)
Diode and continuity test
•
Connect the black measuring wire to the „COM”, the
red one to „V/Ω/Hz” connector. (Note: the polarity of
the red wire is: +)
•
Set the function to „
” position.
•
Touch the wires to the diode's connectors. The screen
shows the opening voltage of the diode.
•
Connect the wires to two points of the circuit. If the
resistance is below 90 Ω the device beeps.
