Operating

• ON/OFF

A short press of the “ON/OFF” button will turn on or off the caliper.

• mm/in

The unit of measurement can be selected by pressing “mm/in” button. The

displayed value will be converted to the corresponding unit and either “in”

will be displayed in the lower left corner for inch of the display or “mm” in

the lower right for metric.

• ORIGIN

Press “Origin” button to reset origin zero. Manufacture pre-set Origin at zero

position where the two outside measuring surfaces gently touched. If Origin

needs to be reset, press Origin key for 5 seconds and display will show

“0.00mm” and a new origin zero has been set.

• ABS/INC

The caliper is normally used in absolute (ABS) mode providing readings from

the origin established with the jaws closed. An incremental mode is available

to provide measurements from a temporary zero. For example if the work

piece nominal value of 0.704 is desired open the jaws with the slider to this

position and lock the slider with the slider locking screw. Press the ABS/INC

button and the display will change to zero and the “INC” will be displayed in

the upper right corner. The work pieces can then be measured with the

drawing tolerance
