With this method, we can correct the zero and span shift of the instrument when it occurs. These two adjustments correspond exactly to the \(b\) and \(m\) terms of the linear function, respectively.

Pressure Gauge With External Adjustments.

Stainless steel pressure gauge suitable for liquids or gases that are not aggressive to stainless steel. Adjust the linearizing adjustment so that the pointer reads at 50% of the maximum scale reading. One adjustment is called the zero while the other is called the span.

Be Careful Not To Push The Fill Plug All The Way In.

External screw with locking mechanism: Safety pattern solid front pressure gauges. The zero adjustment on these gauges should be checked frequently.

You May Need To Adjust The Gauge Many Times Before The Gauge Is.

Take your flat head screw driver and place it carefully near the fill plug on the top of your gauge. A “span” adjustment is always achieved by multiplying or dividing some quantity, just like the slope m forms a product with our input variable x. Slowly pressurize the gauge to its full scale and slowly release the pressure back down to zero 3.

Some Devices Such As Analogue Output Sensor, May Have A Small Zero Offset Because It Does Not Have Sufficient Fine Adjustment To Set The Zero Reading Exactly.
