There is no adjustment or "calibration" for this.
The 3 types are: Manual, Digital and Aneroid.

To calibrate a pressure gauge, first ensure it is clean and free from any damage. Connect the gauge to a calibrated pressure source, such as a pressure calibrator or a known reference gauge. Gradually increase the pressure and compare the readings on the gauge to the reference value at multiple points across its range. Adjust the gauge as necessary, following the manufacturer's instructions, to ensure accurate readings.
To calibrate a machinist's square, you can use a surface plate and gauge blocks. Place the square on the surface plate and use gauge blocks to check if the blade is perpendicular to the surface. Adjust the square if necessary to ensure accuracy.
To calibrate a feeler gauge using a caliper, measure the thickness of the feeler gauge blades at multiple points along the length using the caliper. Check these measurements against the stated thickness of the blades to ensure accuracy. Make any necessary adjustments to the feeler gauge if the measurements deviate significantly.
To calibrate a force gauge, you typically need a calibration kit with known weights. Apply the known weights to the force gauge and adjust it to match the reading on the weights. Repeat this process for different weight loads to ensure accuracy across the gauge's range. It is recommended to follow the manufacturer's instructions for calibration to maintain the tool's accuracy.
Vehicles do not come with a digital car gauge. You have the option to install a gauge in your car at the time purchase.
Calibrating a slip gauge involves checking its dimensions against a standard reference gauge or measuring instrument. First, ensure the slip gauge is clean and free of contaminants. Then, use a calibrated micrometer or digital caliper to measure the gauge, comparing the reading to its nominal value. Adjustments are made based on discrepancies, if necessary, to ensure accurate measurements. Regular calibration against certified standards is essential for maintaining precision.
To calibrate compound gauges, you will need a calibration pump and a pressure calibrator. Connect the compound gauge to the calibration pump and apply pressure using the pressure calibrator. Compare the readings on the compound gauge with the readings on the pressure calibrator and make necessary adjustments to bring them into alignment.

Analog gauges do not use digital numbers or digital displays. Analog gauges use dials or a pointer. Think hands moving around a dial as in an analog speedometer. If it has digital numbers then it is not an analog gauge it is a digital gauge.
