Measuring an object from the inside:
j Place the internal measuring jaws 2 against the object
you want to measure.
j Turn the handwheel 7 outwards anti-clockwise. Move the
internal measuring jaws 2 apart until they touch the object
on both its inner sides. Please ensure that you do not
damage the object you want to measure by subjecting it to
too much pressure.
Measuring the depth of an object:
j Move the depth-measuring blade 6 out of the calliper.
j Put the depth-measuring blade 6 in position until it touches
the surface (e.g. inside a hole).
j Slide the body of the calliper downward until you feel
resistance.
j Ensure that you do not damage the depth-measuring blade
6 or the object you want to measure by exerting too much
pressure on them.
j The LCD display 5 now displays the dimensions.
j after carrying out the measurement, move the external
measuring jaws
11 / internal measuring jaws 2 together
again by turning the handwheel 7 inwards clockwise.
j Switch the LCD display 5 off again by pressing the
ON / OFF key 10 .

Examples of use
Tip: When measuring, always proceed as described in the
chapter on using the calliper.
Comparison of plug and socket (see fig. C):
j First measure the dimensions of the plug.
j You may wish to make a note of the measurement.
j Then measure the socket.
Deviation from a reference value (see fig. D):
j Measure a reference object (in this case a).
j Leave the measuring jaws 2 / 11 in this position and press
the key to obtain the zero setting (ZERO) 9 .
j Then measure the second object. The LCD display 5 now
shows the deviation of the measurement of the second object
to that of the reference object (a).
Measuring the thickness of the floor of an object
(see fig. E):
j First measure the depth of the object.
j Leave the depth blade 6 in this position and press the key
