Deviation from a reference value (see fig. D):
j
Measure a reference object (in this case A).
j
Leave the measuring jaws
2
/

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

in this position and press the key
to obtain the zero position (ZERO)
9
.
j
Now measure the entire object. The LCD display
5
now
shows the thickness of the floor of the object.
Measuring the distance between two identical
holes (see fig. F):
j
First measure one of the two, equally sized holes.
j
Leave the measuring jaws

Troubleshooting
The device contains sensitive electronic components. That is why
it experiences interference when in close proximity to radio
transmission devices. If any indication errors appear in the
display, remove such devices out of the proximity of the calliper.
