It also causes faster wear of the caliper measurement surfa-
ces..
3. Do not apply voltage (e.g. of electric tester) to any part of the
caliper, it may damage electronic assembly of the caliper.
4. Remove battery from the caliper, when it is not to be used
for a long time.

CALIPER OPERATION
Ensure all caliper surfaces are free from grease, dust, dirt and
filings before starting to use the caliper. Use a cloth to wipe all
measurement surfaces of the caliper before starting to work.
Use of any organic fluid is forbidden. Ensure that all buttons and
LCD display operate correctly.
To make a measurement:
– loosen slider lock screw (fig. 1/G),
– press ON/OFF button (fig. 1/L)
– select desired measurement unit by pressing the unit
toggle button (fig. 1/I) – every time the button is pressed,
measurement units change,
– use the slider shift roller (fig. 1/H) to move the jaws closer;
displayed value (fig. 1/F) should be zero; when it is not so,
press the zero adjustment button (fig. 1/J),
– display can be zeroed at any point within the measurement
range.
Measuring external dimensions (fig. 2)
– Position measured object as close to the guide reference
surface as possible,
– Move measurement jaws to contact outer surfaces of
measured object.
Measuring internal dimensions (fig. 3)
– Slide internal measurement jaws as deep as possible,
– Move measurement jaws to contact inner surfaces of
measured hole.
