section. It is recommended to use alkaline batteries. To install a battery, open the instrument cas-
ing 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 casing. Connect the battery,
according to its terminal marking, close the casing or battery compartment cover. If a battery
symbol appears on the screen, the battery must be changed. It is recommended to replace the
battery as soon as possible, after the battery symbol appears, to ensure measurement accuracy.
Fuse replacement
The device uses a fast-acting safety fuse. In case of damage, replace the fuse with a new one
with identical electrical parameters. To do so, open the meter's casing, following the same proce-
dure as for battery replacement and the safety rules, and change the fuse to a new one.
Switching 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 measured quantity and its range.
The meter will turn off automatically, if not in use. After about 15 minutes of inactivity, the meter will
automatically turn off . This will reduce battery consumption. The user will be notifi ed by an audible
signal, approximately one minute before the power supply is turned off .
The SEL/HOLD button
The button is used to manually select the measured value for set points defi ned by more than
one measuring symbol. If pressed and held for approximately 2 seconds, the button will keep the
value currently displayed on the screen. In this case, a HOLD symbol appears on the screen.
The RANGE/* button
The button is used to manually change the measuring range for a given quantity. When pressed,
the AUTO symbol will disappear. Pressing the button again will switch the range in the order
shown in the table.
To exit the manual range selection, move the selector to a diff erent fi eld, and then return to the
previous one. Keeping the button pressed for approx. 2 seconds will activate backlight for the
display. Press the button again and hold it for approx. 2 seconds to turn off the display's backlight.
Connecting measuring cables
If the measuring cable plugs are capped, remove the caps before plugging the measuring ca-
bles to the sockets. Connect the measuring cables, in accordance with the instructions provided
in the manual. Next, remove the caps (if any) on the measuring section and proceed with the
measurements.
Built-in buzzer
The meter has a built-in buzzer that beeps briefl y each time the selector is moved or a button
is pressed to confi rm the action has taken place. The buzzer will emit several beeps per minute
before the meter is automatically switched off and one long beep immediately before it is auto-
matically switched off . The meter switches off automatically 15 minutes after the last pressing of
the button or a change in the selector's position.
MEASUREMENT PROCEDURE
Depending on the current position of the range switch, the display will show three digits. If the
battery needs to be replaced, the multimeter indicates this by showing the battery symbol on
the display. If the sign "–" appears on the display before the measured value, it means that it
has a reversed polarity relative to the meter's connection. If an overload symbol appears on the
display, it means that the measuring range has been exceeded and the measuring range must
be changed to a higher one.
In the case of measurements of unknown values the meter should be set to the AUTO mode, in
which case it determines the best measuring range by itself. If the selector is set to measure AC
current or voltage, the meter will start measuring in the True RMS mode. This means that the
real eff ective value of the alternating wave will be measured. If a non-sine wave is measured, the
