to take precise measurements and easy readings from 0 to 25 mm
Preparation for operation:

Clean the measuring surfaces and the guide. Use a cotton cloth for this purpose. Do not use solvents or acids
check the zero position for this purpose, bring the measuring surfaces into contact by turning only with the friction clutch knob. Then press and hold for about 2 seconds the button described ON/OFF---SET", until the indication is zeroed
check that all buttons, switches and display are working properly
Basic measurement methods:

Absolute measurement
loosen the locking clamp
switch on the device by pressing the "ON "button
select the measurement unit by pressing and holding the "ABS/INC---UNIT "button for about 2 seconds
.
each time the measurement result will alternately be displayed in inches or millimeters
the result in inches is described by the "in" symbol shown on the display screen
press the "ABS/INC---UNIT" button until the "ABS" symbol appears on the display
.spread the measuring surfaces to a distance slightly larger than the object to be measured
then turn the stylus knob to roughly adjust, then continue tightening by turning the friction clutch knob
stop tightening when the clutch engages
read the measurement result from the display
Relative measurement
the measurement principle corresponds to that described above, but the relative measurement is used to compare two dimensions
.when the "ABS/INC---UNIT" button is pressed, the indication will be reset to zero, and the display will show the symbol "INC"
after measuring again, the difference in dimensions can be read
