higher current the built-in fuse will melt.
measuring resistance
Set the function switch to the "Ω
•
position.
Connect the measuring wire and the
•
measuring pin to the measured resistor, the
measured value is displayed on the screen.
Note:
If the resistance is greater than 1mΩ it may take a few
•
seconds for the display to stabilize. This is normal.
If there's a tear between the measuring pins or the
•
circuit is open, the screen will display an overflow.
Before measuring resistance, make sure that the
•
measured circuit is not under power and all capacitors
are discharged.
measuring diode
Set the function switch to the "Ω
•
position. Press the "SELECT" button until you
see a " " sign on the screen.
Connect the measuring wire and the
•
measuring pin to the measured diode (the
pin should go on the anode, the wire on the
cathode of the diode).
The opening voltage of the diode is displayed
•
on the screen.
measuring/displaying continuity
Set the function switch to the "Ω
•
position. Press the "SELECT" button until you
see the " " sign on the screen.
Connect the measuring wires and the
•
measuring pin to the measured circuit. If the
resistance is lower than 30Ω, the device will
beep.
Automatic power off
If you do not use the device for at least 15
•
minutes it will turn off automatically and
go into standby mode. To turn it on again,
press the "HOLD" button or switch to another
function.
Battery replacement
To replace the battery remove the screw from
•
the battery container lid, replace the battery
to one of the same type and screw the lid back
on.
Note:
Before replacing the battery disconnect the measuring
•
wire and the pin from the measured circuit.
Switch the device off before replacing the battery.
•
Pay attention to the correct polarity when inserting the
•
battery. The device may be damaged if the battery is put
in backwards.
/ "
Only use the prescribed battery type (Cr2032)
•
Fuse replacement
Fuse replacement is seldom necessary, and even
if it is, it is mostly due to user error. Use only the
following type of fuse for replacement:
F250mA/250V (Ř5x20mm).
/ "
To replace the fuse:
Turn off the device.
•
Remove the "A" screw and the "B" cover.
•
Remove the "D" screws. Remove the "C"
•
battery container lid and take off the back
cover of the device.
Carefully remove the fuse ("E")
•
Insert the new fuse.
•
Put the device back together.
