OPERATION OF THE MULTIMETER
ATTENTION! In order to protect from electric shock before the housing of the device is opened, disconnect the meas-
urement cables and turn the meter 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 two screws at the bottom of the meter. Connect the battery in
accordance with the marking of the terminals, close the housing and replace the screws.
Replacement of the fuse
The device is equipped with a 0,5A/250V quick-break equipment fuse. If the fuse is damaged, it must be replaced with
a new one of the same electrical parameters.
To do so, open the housing of the meter and proceed as in the case of replacement of the battery, observing the safety
principles, to replace the fuse.
MEASUREMENTS
Depending on the actual position of the range switch in the display three significant digits will be displayed as well as
the measurement range below the coma. In case of measurements in the highest voltage ranges a lightning symbol
will be displayed. If it is necessary to replace the battery the multimeter indicates this displaying the battery symbol. If
before the measured value the “-” symbol is displayed then the measured value has an opposite polarization in rela-
tion to the connection of the meter. If only “1” is displayed, then the measurement range is exceeded, and it is neces-
sary to increase the measurement range. In case of measurements of quantities of unknown values, set the highest
measurement range and only after the initial measurement change the measurement range to the adequate one.
ATTENTION! The measurement range of the meter must not be lower than the measured value. It might dam-
age the meter and cause an electric shock.
The correct connection of the leads:
The red lead must be connected to the socket marked as „VΩ”, „mA” or „A”
The black lead must be connected to the socket marked as „COM”
Measurements of voltage
Connect the measurement cables. Switch the range selector to the position of the measurement of the direct voltage
or alternating voltage. Select the maximum measurement range, connect the measurement cables in parallel to the
electric circuit and read the result of the measurements of the voltage. In order to ensure more precise results of the
measurement you may change the measurement range. Do not ever measure a voltage exceeding 1000V, since it
might damage the meter and cause an electric shock.
Measurement of intensity of the current
Depending on the expected value of the measured intensity of the current connect the measurement cables to the
socket marked as „mA” and „COM” or „A” and „COM”. Maximum intensity of the current measured through the „A”
socket may be 20A and it is not protected with any fuse. Maximum intensity of the current measured through the
socket is 10A. The duration of measurement of a current exceeding 10A must not be longer than 15 seconds. The
maximum power-carrying capacity of the „mA” socket is 200mA. The maximum current and voltage values of the
sockets must not be exceeded.
Connect the measurement cables in series to the tested electric circuit, select the range and kind of the current and
read the result of the measurement. The first stage of the measurements is to select the maximum measurement
range. In order to ensure more precise results of the measurement you may change the measurement range.
Measurements of resistance
Connect the measurement cables to the sockets marked as „VΩ” and „COM”; switch the range selector to the position
of the measurement of resistance. Place the measurements leads at the terminals of the measured element and read
the result. In order to ensure more precise results of the measurement the measurement range may be changed if
required. It is strictly prohibited to measure the resistance of live elements. The measurement range 200MΩ has
a constant amounting to 1MΩ, which must be deducted from the result of the measurement. The constant may be
