The Difference Between Automatic and Manual Calibration

Hi, this is James from ABM Services Group. Here is the link to the form we are going to mention at the end of this video – https://goo.gl/forms/4X0IxlhpK6eOySbJ3

In this video we are going to discuss the difference between manual and automatic calibration.

It’s important to keep in mind that calibration methods for modern devices (as opposed to more ancient devices) can be both manual and automatic depending on what kind of device is being calibrated.

For instance, in this first photo of a US servicemen calibrating a temperature gauge this photo, he’s performing a manual calibration. The procedure is quite complex but overall it involves the following steps:

One depressurising the system and turning the screw to ensure that the needle reads 0.

Two, fully pressurising the system and insuring that the needle reads maximum with an acceptable tolerances.

And finally three replacing the gauge if the error in the calibration process is beyond tolerance as this may indicate signs of failure.

In the second photo we see the use of a 3666c automatic pressure calibrator. This is an example of automatic calibration. This device consists of a control unit housing the electronics that drive the system, a pressure intensifier used to compress gas such as nitrogen, a pressure transducer used to detect target levels in a hydraulic accumulator, and also accessories such as liquid traps and gauge fittings.

It’s a very short form (you can fill it out in under a minute) and then will get back to you with a plan to give you a better idea on how you can gain from calibrating your equipment now.

Thanks for watching and until next time have a great day.
