again if necessary, the relative zero point is not changed until
‘ON-ZERO’ is pressed to set a new relative zero point.
- ‘ON ZERO’ is to turn on/off display and set the reading on
display to be zero. Press it to set zero reading. Keep pressing
it for three seconds to turn off display. Display is
automatically turned off in about 5 minutes if gauge is not
used. Press ‘ON-ZERO’ or move vernier to turn display on.
3. Gage should be checked to make sure that it is properly calibrated
before each use. The reading should be zero when measuring tip
and face are in contact, otherwise press ‘ON-ZERO’ to set zero
reading. Separate and return them to be in contact again to verify if
reading returns to zero.
4. Take care that gage is perpendicular to the rotor to prevent
measurement error. To assure this, keep the flat measuring face in
full contact.
5. To measure a rotor in a position where the display cannot be viewed,
press ‘ON-ZERO’ button and remove gage. Move the measuring tip
and face to be in contact and the reading is the actual rotor
thickness with a ‘-‘ in front.
6. One battery will last for one year of continuous use. If there is
nothing on the display or the digits flash, battery voltage is too,
please replace battery (the positive side of the battery should face
out). If digits do not change when buttons are pressed or vernier is
moved, take out battery and put it back after 1 minute. Remove the
battery if the caliper is not going to be used for a long period of time.
7. Always apply constant force on thumb wheel during calibration and
measurement.
8. Tighten locking screw to hold reading.
9. Working temperature is 32-72ºF. Do not put gage near strong
magnetic field. Keep gage dry, liquid getting into the caliper will
damage electronics. Do not apply voltage on gage like engraving
with electric pen.
10. Measuring tip and face should be carefully protected from being
scratched or damaged. Do not operate abruptly, drop or strike gage.
