GB
forward direction we will read the voltage drop for this diode expressed in mV. In case the diode is connected in the reverse direction
the display will read „O.L". Correctly functioning diodes show a low resistance in the forward direction and a high resistance in the
reverse direction. It is strictly prohibited to test live diodes.
Conduction test
Connect the measurement cables to the sockets marked as „INPUT" and „COM". Use the „FUNC." button to select conduction test.
The buzzer symbol will be displayed. In case the meter is used for conduction measurements, the internal buzzer will emit sound each
time the measured resistance drops below 30 Ω. It is also possible the buzzer will sound within the range between 30 Ω and 100 Ω. It
is strictly prohibited to test the conduction of live circuits.
Transistor test
Switch the range selector to the position marked with the symbol h (measurement gain coefficient of the transistor). Depending on
FE
the type of transistor it must be connected to the socket of the base marked as PNP or NPN making sure the terminals of the transistor
are placed in accordance with the letter indications: E - emitter, B - base, C - collector. If the transistor is functioning properly and
the connection is correct read the displayed result of the measurement of the gain coefficient. It is strictly prohibited to test live
transistors.
Measurement of temperature
Connect the thermoelement leads to the sockets marked as „INPUT" and „COM". Switch the selector of the meter to „Temp". Use the
„FUNC." button to select the adequate measurement unit, namely O F or O C. Put the thermoelement to the measured object. The ther-
moelement supplied with the device permits to realise measurements only up to 250 C. In order to measure higher temperatures it is
O
necessary to purchase a thermoelement that permits to measure higher temperatures. It is required to use thermoelements type K.

MAINTENANCE AND STORAGE

Clean the meter with a soft cloth. Remove heavy soiling with a damp cloth. Do not submerge the meter in water or any other liquid.
Do not use solvents, caustic or abrasive substances to clean the meter. Make sure the contacts of the meter and the measurement
cables are clean. Clean the terminals of the measurement cables with a cloth slightly soaked with isopropyl alcohol. In order to clean
the contacts of the meter, turn the meter off and remove the battery. Turn the meter round and shake it slightly to remove major impuri-
ties from the contacts of the meter. Soak slightly a cotton swab in isopropyl alcohol and clean each contact. Wait until the alcohol has
evaporated and replace the battery. Store the meter in a dry place in the provided case.
