PROPERTIES OF THE DEVICE
The all-purpose meter is a digital measurement device designed to measure various electrical quantities.
Before using the meter, read the whole manual and keep it.
The meter has a plastic housing, a liquid crystal display and a measurement range selector. The housing is equipped with measure-
ment sockets and a transistor test socket. The meter is equipped with measurement cables with plugs. The meter is sold without a
battery.
ATTENTION! The meter is not a measurement device as it is construed within the „Measurement Law"

OPERATION OF THE MULTIMETER
ATTENTION! In order to protect from electric shock before the housing of the device is opened, disconnect the measurement cables
and turn the meter off.
Safety instructions
Do not operate the meter in the presence of an excessive humidity, toxic or inflammable vapours and in explosive atmosphere. Before
each use check the conditions of the meter and the measurement cables. If any damage is detected, it is prohibited to operate the
device. Damaged cables must be replaced. In case of any doubts, consult the manufacturer. During measurements keep the measure-
ment cables and leads by the insulated parts. Do not touch the places of measurement or the sockets of the meter which are not being
used. Before the measured quantity is modified, disconnect the measurement cables. Do not realize any maintenance tasks without
making sure the measurement cables have been disconnected from the meter, and the meter itself has been turned off.
Replacement of the battery
The multimeter is powered with a 9V 6F22 battery. It is recommended to use alkaline batteries. In order to install a battery, open the
housing of the device removing the screws at the bottom of the meter. Connect the battery in accordance with the marking of the termi-
nals, close the housing and replace the screws. If the battery symbol is displayed, the battery must be replaced. For the sake of preci-
