A daily regimen of gage verification, combined with empirical and statistical information gained during scheduled tool calibrations, can help track the optimum time intervals for calibration, keeping the measurement tools on the shop floor and operating at peak efficiency.
Many experts feel that true calibration must be done in an environmentally controlled laboratory, but a daily ritual can help operators track their tools. Daily verification can be as simple as a visual inspection of a caliper to see if the jaws come together and no light shows between them. Or, an inspector can carry a couple gage blocks to audit key or heavily used gages.
