What is calibration?

 Calibration is a crucial process in measurement technology and metrology. Let me break it down for you:

  1. Definition of Calibration:

    • Calibration involves comparing the measurement values obtained from a device under test (DUT) with those of a calibration standard that has a known accuracy.
    • The purpose of calibration is to eliminate any variation in the DUT by adjusting it based on the comparison with the standard.

  2.      

    • Why is calibration necessary?
      1. To obtain meaningful results: Calibration ensures that mea
        suring instruments provide accurate and reliable measurements.
      2. When the sensing system and measuring system are different: Calibration integrates the entire system, accounting for error-producing properties of each component.
      3. Adjusting readout devices: Calibration adjusts readout devices to produce zero output for zero-measured input and display an output equivalent to the known measured input near the full-scale input value.
      4. Environmental conditions: Calibration should be performed under conditions similar to those in which actual measurements occur.

  3. Traceability:

    • Traceability is the property of measurement results, not just the instrument or calibration report. It means that the result of a measurement can be related to a reference through a series of calibration reports.

In summary, calibration ensures that measuring instruments are accurate and reliable by comparing them to known standards. It’s a fundamental step in obtaining meaningful measurement results!

Calibration procedure of Tachometer

Image
  A tachometer ensures accurate readings of rotational speed. Let’s walk through the procedure for calibrating a  non-contact  digital tachometer using a  Fluke 754 Process Calibrator  as a reference standard: Preparation : Familiarize yourself with the tachometer’s user manual to understand specific requirements for calibration 1 . Clean the tachometer and ensure it’s not damaged 2 . Identify Reference RPM: Some tachometers have a built-in reference RPM, while others require an external source. For this procedure, we’ll use the Fluke 754 Process Calibrator as our reference standard. Generate a simulated signal (frequency) using the Fluke 754, along with an LED as the source of our reference value 3 . Adjust the Tachometer: There are no adjustable parts in most handheld digital tachometers, so we’ll verify accuracy only. Point the tachometer’s laser at a rotating shaft with refl...

Pressure gauge calibration procedure.

Image
  C alibrating pressure gauges is essential to ensure their accuracy and reliability. Let’s walk through the procedure step by step:   Inspect the Gauge: Begin by examining the pressure gauge for any physical damage that might affect its performance. Connect to Calibration Device: Connect the pressure gauge to a calibration device (such as a pressure comparator or hand pump calibrator). The calibration device will apply known pressures to the gauge during the calibration process. Record Readings: As pressure is applied, record the readings from the pressure gauge. Compare these readings to the known values provided by the calibration device. Remember that the specific calibration procedure may vary based on the type of pressure gauge and the equipment available. If you have access to a pressure comparator and a master gauge, here’s a more detailed procedure: Identify Parameters: ...

Calibration procedure for Weighing Balance.

Image
  A   weighing balance is essential to ensure accurate measurements. Here’s a step-by-step procedure for calibration:   1.Repeatability Repeatability measures the variation in multiple measurements taken under the same environmental conditions. Perform this test for both full load and half load of the balance. Follow these steps: Press the Zero button on the balance. Place the weight (either half load or full load) on the weighing pan. Note down the reading. Remove the weight without zeroing the balance. Repeat the process at least 10 times. Calculate the standard deviation. 2.Linearity: Linearity assesses the deviation from the nominal value of weight. Ideally, the graph between standard weight and indicated reading should be a straight line. Take readings for different weights (including no load and full load): Press the Zero button on the balance. Place the minimum w...
