according to its terminal marking, close the casing or battery compartment cover. If a battery symbol
appears on the screen, the battery must be replaced. For the sake of measurement accuracy, it is
recommended to replace the battery as soon as possible after the battery symbol appears.
HOLD button
The button is used to retain the measured value on the display. When pressed, the button will ensure
that the currently displayed value remains on the display, even after the measurement is over. Press
the button again to go back to the measurement mode. The operation of the function is indicated on
the meter display with the HOLD sign.
Connecting test leads
If the test lead plugs are capped, the caps must be removed before plugging the leads into the jacks.
Connect the leads in accordance with the instructions in the manual. Now remove the covers (if any)
of the measuring parts and proceed with the measurements.
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 polar-
ity 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.
If the scale of the measured value is not known, set the highest measuring range and reduce it after
reading the measured value. The measurement of small quantities with a high measuring range
involves the greatest measurement error. If you select the highest voltage measuring range, the dis-
play will show “HV” or a lightning symbol. Special care should be taken when measuring quantities
within the highest voltage range to avoid electric shock.
CAUTION! Never allow the measuring range of the meter to be smaller than the measured
value. This can damage the meter and cause electric shock.
The correct connection of the leads is:
The red lead goes in the jack marked “VΩ”.
The black lead goes in the jack marked “COM”.
In order to achieve the highest possible measurement accuracy, optimal measurement conditions
should be ensured. The ambient working temperature should be in the range from 18 to 28
o
C and
relative air humidity <75%.
