button.
Touch the connectors of the device to the
•
resistor and read the measured value from the
screen.
note:
the device may need a few seconds when measuring above
1mΩ to show a stable value. this is normal in such a high
range.
if the inward signal is missing or the circuit is open, „Ol" is
shown on the screen as for overloads.
Capacity measuring
Warning: to avoid damage to the device and
electric shock disconnect the measured circuit's
power source and discharge all high capacity
capacitors!
Set the device to
•
button.
Touch the device to the measured capacitor
•
and read the measured value from the screen.
note:
the device may require a few seconds in a higher range (30
seconds in the 200µF range). this is normal for this range.
When measuring below 4nF the device's capacity value
must be subtracted from the measured result (or you can
switch the device to relative measuring mode with the rel
button and then perform the measuring).
diode measuring
Warning: to avoid damage to the device and
electric shock disconnect the measured circuit's
power source and discharge all high capacity
capacitors!
Set the device to
•
button.
Touch the + pin to the diode's anode and the -
•
one to the cathode.
The display shows the opening voltage of the
•
diode. If the polarity is reversed, the display
shows „OL".

aintenance
Warning: to avoid electric shock, do not let
water get inside the device!
Clean the device regularly with a wet cloth. You
may use water with mild detergent. Do not use
strong detergents, solvents or abrasives!
