A Look at Equipment Calibration Software

With time and continuous use, the accuracy once provided by instruments and equipment will reduce and there will be a need to confirm the integrity of the equipment’s measurements. Like most other things, time takes its toll on machines as well and there are several processes that are followed to maintain the accuracy of machines and instruments and correct any deviations.

Once these deviations are noticed, it doesn’t mean that the equipment no longer works and should be discarded. All that needs to be done is for it to be calibrated and accurate measurements will be restored. 

What is Calibration?

Calibration is the process of determining the accuracy of an equipment. It typically involves comparing a reading from the instrument with that of a standard instrument and measuring any variations. Calibration also includes adjusting an instrument’s accuracy and precision so that its readings are in line with the industry standard. 

Equipment calibration or adjustment is a practice that should be carried out regularly because equipment often deviates from standard owing to mechanical shocks, exposure to extreme pressure or temperature, and overall, hard operating conditions. How often this process is carried out depends on two main factors, which are:

  • The tolerance level of the equipment, and;
  • The level of importance placed on its readings and measurements. 

For an instrument to maintain accuracy, it is essential that every important component conforms to the specified standard. Visit https://www.sciencedirect.com/topics/engineering/mechanical-shock to learn more about mechanical shock. 

Types of Calibration

Calibration can be done on several types of equipment across various sectors. However, we’ll be looking at the most common types carried out across board. They include:

  • Pipette
  • Pressure
  • Flow
  • Temperature
  • Mechanical, and;
  • Electrical calibration. 

Pipette

This is important for laboratories since they frequently make use of pipette for measurement. There are several types of pipettes used in laboratories today like electronic pipettes, multi-channel pipettes, and single-channel pipettes. This type of calibration follows several protocols and processes and factors like operator training application among others are to be carefully considered. 

Pressure

Pressure calibration is one of the most commonly performed types of instrument adjustment. Under this type of services, hydraulic and gas pressure are usually measured using different types of gages, calibrators and pressure balances. 

Frequently calibrated pressure instruments include:

  • Barometers
  • Digital indicators
  • Analogue pressure gauges
  • Digital pressure gauges
  • Transmitters
  • Test gauges

Flow

Flow meters that check energy/fuel quantity, product quality and quantity, or that function in critical process need to be routinely calibrated. There are four main types of flow meters that are frequently calibrated, and they are:

  • Turbine meters
  • Rotameters
  • Thermal mass flow meters
  • Laminar flow meters

Temperature

Calibrating temperature equipment is crucial in processes where their readings play a vital role. This type of calibration is usually carried out in a controlled environment and advanced mechanical and electrical thermometers are used in the process. The following are equipment used in measuring temperature that are calibrated on a regular basis:

  • Dial thermometers
  • Thermal cameras
  • Furnaces and chambers
  • Infrared meters
  • Weather stations
  • Data acquisition systems
  • Thermocouples and thermometers
  • Thermistors and Platinum resistance thermometers (PRTs)

Mechanical

This type of adjustment can be carried out on a wide range of mechanical equipment. In a temperature-controlled environment, elements such as force, dimension, mass, volume, torque, angle, vibration, and flatness are all calibrated during the process. Some of the mechanical instruments frequently calibrated are:

  • Scales and balances
  • Weight sets
  • Mass sets
  • Micrometers
  • Accelerometers
  • Force gauges and load cells
  • Verniers
  • Torgue wrenches
  • Height gauges

Electrical

In electrical calibration, elements like voltage, resistance, and frequency are checked. It should be done according to the UKAS accredited standards for maximum credibility.  The following are electrical instruments that are frequently calibrated:

  • Data loggers
  • Loop timers
  • Clamp meters
  • Insulation testers
  • RCD
  • Counter timers
  • Multi-meters
  • Electric meters
  • Oscilloscopes

Equipment Calibration Process

The process of calibrating an equipment varies depending on a number of factors like the type of instrument, the standards to follow, and how crucial the role of the equipment is in an operation. 

That said, the following processes can be followed to calibrate an equipment:

  • Instrument Design Consideration: The first order of action is carefully considering the design of the equipment to be adjusted. 
  • Follow Instructions: Technicians should follow the specified instructions for calibrating a particular instrument. Deviation or use of an inappropriate calibrator may result in inaccurate results.
  • Confirm Tolerance Value: This should also be taken into consideration during the process. Each calibrator has a unique tolerance level due to normal variation in quality control processes and instrumentation. It was worth mentioning that a number of factors including the country where the process is carried out and the industry may affect the tolerance level. 
  • Accuracy Ratio: The accuracy ratio is also important in the process. It reveals the accuracy of the standard when compared to that of the equipment to be calibrated. Ideally, the accuracy should be at least 4:1. 
  • Stick to Standards: All processes should follow all national and internationally recognized standards. 
  • Carry out Uncertainty Analysis: This is essential in evaluating factors that may have affected the final results.  

What is Calibration Software?

Calibration software is a computer program designed to automate calibration processes. Because industry standards are built into them, processes are much more accurate. With this software, organizations can make improvements to their equipment with minimal human intervention. 

With this equipment calibration software, adjustment of instruments is scheduled as necessary and done to recognized standards. 

Benefits

There are many benefits that companies stand to enjoy from utilizing this software. For one, records and history of previous calibrations can be easily accessed to quickly fix current issues. Increased efficiency is another benefit of this type of software since it helps to automate labor-intensive work, thereby reducing production downtime. 

As earlier mentioned, instruments can be calibrated following regular schedules when this software is integrated into the workflow. This means that no calibration is ever missed since many companies can’t afford to have calibration errors. 

Conclusion

In industries today, accuracy is extremely important when it comes to delivering excellent services and manufacturing quality products. These can only be achieved when the equipment utilized in these processes are in prime shape, making calibration a necessity.
