Operation
• To operate the caliper, simply slide Main Body (5) up or down the Stainless Steel Guide

the movement of the Main Body (5).
• The Digital Display (4) turns on automatically when the main body slides along the
Stainless Steel Guide (8). It can also be turned on or off by depressing the On/Off
Switch (11).
• To measure variation between several components, measure one and depress the
Zero Button (10). Measuring others will then highlight any variations by displaying any
figure other than zero.
• Before you take a measurement, clean the faces of the jaws with a soft cloth and press
the Zero Button (10) to zero the unit.
• To switch between metric and imperial, depress the Unit Change Button (2).
• To lock the calipers at a specific measurement, rotate the Scale Lock (3) clockwise. To
unlock, rotate the Scale Lock (3) anti-clockwise.
NOTE: It is the user’s responsibility to obtain calibration certification if required.
Maintenance
• Ensure that the Jaws (1 & 12) are clean from debris; otherwise it may affect the
accuracy of the measurement.
• Keep the stainless steel guide clean from dirt and grease, dirt could damage the main
body and may invalidate the warranty.
