Calibration
The calibration of this tester includes low end calibration, high end calibration, and display value
calibration. The device comes factory calibrated. If the reading is out of the indicated range of
the test blocks when checking the accuracy or if you replaced the pressure pin you need to
calibrate the device.
NOTE: It is necessary to loosen the main spindle adjusting screw before performing a
zero calibration or a full scale calibration.
6.1
Low end calibration
Press and hold the Power / Menu key for about 9 seconds until
‘’
’ is shown on the display.
Release the key and a digit appears on the display. Press the Maximum / Plus key or the
Average / Minus key to adjust the digit until it equals the indicated value on the pin length
calibration block. Press the Power / Menu key to exit.
Use a small screw driver to loosen the main spindle adjusting screw in counter-clockwise
direction until the end. Put the pin tube into the hole of the pin length calibration block and push
the tester so that the pin draws back completely into the pin tube. The reading value should
equal the thickness value indicated on the pin length calibration block. If it is exceeded, press
the low end calibration button. The standard value will be displayed. Release the low end
calibration button. The low end calibration is now completed.
6.2
High end calibration
Use a small screw driver to loosen the main spindle adjusting screw in counter-clockwise
direction until the end. Place the tester on a solid flat surface, such as a glass plate. Push the
tester so that the pin draws back completely into the pin tube:
‘100.0’ should be shown on the
display. If it is exceeded, press the high end calibration button and
‘100.0’ will be displayed.
Release the high end calibration button. The high end calibration is now completed.
6.3
Display value calibration
Use a small screw driver to adjust the main spindle adjusting screw. The display value
decreases when turning it clockwise and increases when turning it counter-clockwise. Adjust the
screw until the measured value is in the indicated range of the 2 standard blocks.
