3. Improper handling may cause damage or poor accuracy e Do not scratch instrument for example by writing ID number Do not move the Vernier slide without pressing Thumb Lock Excessive force applied to Slide may cause damage or affect accuracy Do not disassemble or modify Do not remove the vernier slide Please do not attempt to disassemble or modify as it may cause damage or poor accuracy CALIBRATION in order to maintain instrument accuracy it is recommended that accuracy is confirmed through calibration on a periodic basis Wear of measuring surfaces from repeated use may affect accuracy and periodic accuracy checks should be performed We provide calibration services Please contact agent in country of purchase to make arrangements l PREPARATION FOR USE Before using the caliper follow the steps below Do not apply excessive force to Vernier Slide Pushing against slide or attempting to move without pressing the Thumb Lock may cause damage or inaccuracy Wipe off any corrosion dirt or oil from measuring surfaces and slide contamination of surfaces may cause measurement error Allow the caliper and object to be measured time to reach the same temperature A temperature difference between the object to be measured and the caliper may cause measurement error Allow enough time for the temperatures to equilibrate Performing an accuracy check Jaw Alignment In closed position make sure the mea
