Zero Calibration plate
To check whether the tester is accurate, just Insert the indenter into the hole of the calibrated test Block. Apply enough force to make firm contact between the top surface of the test block and the presser foot. The reading
should agree with the value stamped on the test block. If not, just carry out Zero calibration and High end calibration.
Hold the durometer vertically with the point of the indenter hanging in the air, the reading on the display should be '0'. If not, depress the 'ZERO' key to make the tester display '0' .
High end calibration
Just place the indenter onto a flat glass, apply enough force to make firm contact between the glass and the presser foot. The readings on the display should lie between 99.5 and 101. If not, press CAL key to carry out high end calibration.
When the battery symbol appears on the display, it is time to replace the batteries.
Slide the Battery Cover away from the tester and remove the batteries.
Install batteries paying careful attention to polarity.
Readings below 10HD for Shore D type may be inexact and should not be reported for some materials. Measurements should be made on a Shore A type.
Readings above 90HA for Shore A should be made on a Shore D type durometer
