Theoretical Cal.,  no linearisation - page 1

Set your calibration method to THEORETICAL - see previous pages

As an example, let us assume we want to calibrate the display for a pressure sensor input.

Let us also assume that we know from the calibration sheet which came with the pressure
sensor, that it has an output of 0-20mV and a rated capacity of 0 to 50 kg
.

We need to enter these figures into the display...

Start with the full scale SPAN setting...

Press the Set2 button for around 3 seconds.

The display will briefly show 

theor

,  to confirm that we

are in the theoretical setup mode.

Choose with the up or down arrows and press OK.

Set to highest input signal level which was
20mA, according to the sensor calibration
sheet in our example.

You can change the value of the  brightest
digit  with the UP or DOWN buttons.
Brighten other digits with the DIGIT button.

Press OK when done...

In HI will appear briefly, followed by a numeric
value, which you can set...

The numeric value will need to be the High
input signal level ...

Lockout notes:

 

Cal Lock switch = OFF when changing.  Switch Cal Lock to ON after changing
