Are Your Measurements correct?

All Measurements are connected with a certain amont of Mesurement Error. There are a lot of factors wich effect the magnitude of error, i.e.

– the Instrument´s own Error and Precision
– the Method, Connection or selection of Instrument Type
– Influence of electrical fields, dirt, temperature or vibrations
– selection of Measurement Range, reading error or simply wrong connections or wrong use
– the Error may be small or large, but You can be sure of one thing:

You are always measuring with an Error. It may be small or large. Sometime it may be negliable, but it is always good to know the size of Error.

If You want to achive right Quality for Your measurements, one link in the Quality Chain is to calibrate Your Test Equipment regulary and in that way take control over their influence of Measurements.

Many Errors can be eliminated by selection of Methods and Instruments, but if the Measurement Error of the Instruments is unknown, it´s possible that the results may cause low Quality of Your Products or Services delivered to Your Customers.

Imagine, If You are to fill up the Petroltank in Your car and pay for 60 litres, but You only have filled up 58 litres! Or if You buy a 2.5 kg Steak and have to pay for 3 kg! You would not accept that and therefore Petrolpumps and Scales have to be calibrated or verified  regulary.

Also in the Industry calibration is important. A Base Station for Mobile Phones wich not detect the Phones around generates no money if it is not able to connect  the calls. Therefore all major telecom industries calibrate their Test Equipment to be certain that their products work properly in the field.

If the Errors are detected early in the production chain, then it is more cost efficient to correct them.
