TEMPERATURE MEASUREMENT (TEMP)

Connect th ered temperature probe to 

 socket, and the black one to 

the “COM” socket. Set the dial to „TEMP” function. After the measurement 

stabilized, read the displayed value. Attention! The supplied K-type thermo-

meter probe can be use up to 300°C maximum for continuous measurement.

BATTERY AND FUSE REPLACEMENBT

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. Befo-

re battery/fuse replacement, turn off the device and unplug the probe cables. 

For battery replacement remove the screw from the rear panel. For fuse repla-

cement first remove the instrument from its case then remove the screws from 

the rear panel. Replace the battery/fuse. Observe the correct battery polarity. 

Replace the cover and tighten the screws.

Warning:

Before opening the instrument, make sure that the probe cables have 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.

MAINTENANCE

In order to open the outer shell of the multimeter, first unplug the probe cable, 

then unscrew the 2 screws from the back panel of device, then carefully re-

move the back cover. Before opening up the multimeter, you should be aware 

that dangerous voltage may be present in some of the capacitors even if the 

device is switched off. 

The calibration, maintenance and servicing of the multimeter should only be 

performed by a specialist who is completely familiar with the operation of the 

multimeter and the shock hazard involved. If not planning to use the multime-

ter for an extended period of time, please remove the battery and avoid storing 

the unit in excessively warm or humid environments.

 If necessary, replace the fuse with one matching the parameters listed above. 

Do not use any abrasives or solvents on the device. Only use a damp cloth or 

mild detergent for cleaning the unit.

SAFETY PRESCRIPTIONS, WARNINGS

Do not load on the equipment more than 600 V AC / DC voltage, nor greater than 

10 A AC / DC current! 

Do not connect any voltage-source in   , diode, interruption testing, thermometer, 

brightness-, noise level-, capacity-, humidity- measurement function! 

Voltage should not be greater than 600 V DC or ACEFF between the common 

input and the grounding. 

During the measurement, only change the function after the measuring cord has 

been removed!

Be careful when working with over 60 V DC or 30 V ACEFF voltage!

Keep in mind that some equipment (TV, switching power adapter ...) may cause 

harmful voltage surges!

If the unit is used near strong electromagnetic interference, please note that the 

multimeter’s operation can become unstable or it may indicate malfunction.

Never exceed the safety limits specified in the instructions for each measurement 

range. 

Never use the unit without its rear panel fully attached. 

Remove from circuit and discharge the high voltage capacitors before measuring 

resistance, interruption, diodes or capacity.

Be very careful when working with bare cables or bars.

If any irregular operation is detected on the multimeter, immediately switch it off 

and have it serviced.

If the value to be measured is unknown, check the highest possible measurement 

range on the multimeter, or whenever possible, select the automatic measurement 

range mode.

Before rotating the limit selection switch, disconnect the probe cable from the mea-

surement circuit. 

Never perform resistance or interruption measurements on circuits under power.

When performing measurements on TV sets or circuits with high AC, always re-

member that there might be high amplitude voltage on the test points, which can 

damage the multimeter.

If the battery symbol appears on the display, the battery must be replaced imme-

diately. Low battery voltage may result in measurement errors, electric shock, or 

even injury.

Keep your fingers away from the connecting sockets during measurements.

Do not use the multimeter in the presence of flammable gas, vapours or dust.

Before each use, check the unit in order to ensure proper operation (e.g., using a 

known voltage source).

Waste equipment must not be collected separately or disposed 

of with household waste because it may contain components 

hazardous to the environment or health. Used or waste equip-

ment may be dropped off free of charge at the point of sale, or at any 

distributor which sells equipment of identical nature and function. Dispo-

se 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 toget-

her 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.
