Safety instructions
Do not operate the meter in an atmosphere with excessive humidity or in the presence of toxic or fl ammable vapours,
or in an explosive atmosphere. Before each use, check the condition of the meter and the measurement cables. In
case of noticing any faults, do not start operation. Replace damaged cables with new ones, free from defects. If in
doubt, contact the manufacturer. During measurement, hold the measurement cables (tips) only by the insulated
sections. Do not touch the measurement points or unused jacks of the meter. Disconnect the measurement cables
before changing the measured quantity. Never carry out maintenance work without ensuring that the measurement
cables have been disconnected from the meter and that the meter itself has been turned off .
Replacing the battery
The multimeter requires batteries, the number, and type of which are defi ned in the technical data section. It is recom-
mended to use alkaline batteries. To install a battery, open the instrument housing or the battery compartment cover
on the underside of the meter. Before accessing the battery compartment, it may be necessary to remove the cover
on the meter housing. Connect the battery according to its terminal marking, close the housing or battery compart-
ment cover. If a battery symbol appears on the screen, the battery must be replaced. It is recommended to replace the
battery as soon as possible, after the battery symbol appears, to ensure measurement accuracy.
Fuse replacement
The instrument uses a fast-acting safety fuse. In case of damage, replace the fuse with a new one with identical
electrical parameters. To do this, remove the fl exible housing cover, remove all screws fi xing the two parts of the
housing and open the meter housing, replace the fuse with a new one. The parameters of the fuse are indicated
on the fuse housing. When replacing both fuses, it is recommended to replace the fuses one by one, so as not to
change them with places.
Turning the meter on and off
Set the measurement switch to the OFF position to turn the meter off . The remaining switch positions activate the
meter and make it possible to select the measurement quantity and its range. The meter has a function of automatic
turning off in case of inactivity of the user; after about 15 minutes from the last user's reaction, the meter will turn off
automatically. This will reduce battery consumption. If the meter turns off automatically, pressing the SEL or V.F.C
button restores the meter to operation.
SEL button
Press the button to select measurement quantity in the case of the settings of the main switch described using few
quantities. Change the measurement quantity by pressing this button.
V.F.C button
It is a button to measure the voltage for the changing frequency of the measured signal. Start the measurement by
pressing the button.
Flashlight symbol button
It is a button to turn on and off a small fl ashlight located in the front panel of the housing. The fl ashlight is designed
to illuminate the workplace.
HOLD button
The button is used to retain the measured value on the display. When pressed, the button will keep the currently
displayed value on the display, even after the measurement is over. Press the button again to go back to the meas-
urement mode. The operation of the function is indicated on the meter display with the HOLD sign.
Connecting the measurement cables
If the measurement cable plugs are capped, remove the caps before plugging the measurement cables into the jacks.
Connect the measurement cables in accordance with the instructions provided in the manual. Next, remove the caps
