Diode and interruption testing
Diode testing: Connect the red probe cable to the
socket, and the black
one to the “COM” socket (the red probe is for “+” polarity). Set the dial to the
position. Use the “FUNC” pushbutton to set the diode testing ( ) function. Con-
nect the red probe cable to diode’s anode, and the black one to its cathode. The
display will show the diode’s approximate forward voltage. If the connection is
reversed, “OL” will appear in the display.
Interruption testing: Connect the red probe cable to the
socket, and the
black one to the “COM” socket. Set the dial to the
position. Use the “FUNC”
pushbutton to set the interruption testing ( ) function. Connect the measurement
probe to the circuit to be tested. If the circuit is connected to a power source, switch
of the power source and discharge the capacitors before starting measurement.
Short-circuits (less than 50 Ω) will be indicated by the built-in buzzer.

Capacity measurement ( )
Connect the red probe cable to the
socket, and the black one to the
“COM” socket. Set the dial to the position. Connect the measurement probe
to the circuit to be measured. If the capacitor to be measured is connected to a
circuit, switch of the power source and discharge the capacitors before starting
measurement.
Note: Capacity measurement only works with automatic measurement range se-
lection. When performing measurements please note that the larger the capacity
(µF) being measured, the more time it takes for the multimeter to take an accurate
measurement.

Resistance measurement (Ω)
Connect the red probe cable to the
socket, and the black one to the “COM”
socket. (The red probe cable is “+” polarity). Set the dial to the
position. Use
the “FUNC” pushbutton to set the resistance measurement (Ω) function. If the
resistor to be measured is connected to a circuit, switch of the power source and
discharge the capacitors before starting measurement.

Battery and fuse replacement
If the “ ” icon appears on the display, the batteries require replacing. The
fuse only needs to be replaced rarely due to errors associated with use. Prior top
replacing the battery/fuse, turn off the instrument and unplug the probe cables.
When replacing batteries, remove the screw from the back panel/when replac-
ing the fuse first remove the battery compartment lid then also remove the screw
located below the instrument support arm on the back panel. Lift off the cover.
Replace the battery/fuse. Observe the correct polarity. Secure the cover(s) using
the screw(s). Replace the battery/fuse. Observe the correct polarity. Replace the
cover and tighten the screws.
Warning:
Before opening the instrument, make sure that the probe cable has been removed
from the measuring circuit.
Replace and tighten the screws so that the device operates in a stable manner
during use and accident hazards are avoided.

Waste equipment must not be collected separately or disposed of
with household waste because it may contain components hazard-
ous to the environment or health.
Used or waste equipment may be dropped off free of charge at the point of sale, or
at any distributor which sells equipment of identical nature and function. Dispose
of product at a facility specializing in the collection of electronic waste. By doing so,
you will protect the environment as well as the health of others and yourself. If you
have any questions, contact the local waste management organization. We shall
undertake the tasks pertinent to the manufacturer as prescribed in the relevant
regulations and shall bear any associated costs arising.
Batteries, whether alkaline or rechargeable, must not be handled together with
regular household waste. It is the legal obligation of the product’s user to dispose
of batteries at a nearby collection center or at a retail shop. This ensures that the
batteries are ultimately neutralized in an environment-friendly way.
