Ace the 2026 Calibration Technician Challenge – Measure Your Success!

Low calibration limits are determined by subtracting tolerance from the test point. In the context of calibration, the test point represents the desired measurement or standard against which the equipment is being calibrated. Tolerance is the allowable deviation from this test point, which accounts for variations in measurement or performance that may occur due to factors such as environmental conditions or the inherent capabilities of the measuring device.

By subtracting the tolerance from the test point, you establish the lowest acceptable value that still falls within the permissible range of accuracy for the equipment. This ensures that the calibration process maintains the required precision and reliability expected for the instrument being tested. It reflects the minimum threshold for performance; any readings below this limit suggest that the device may not be functioning correctly or may require adjustment.
