Setting calibration parameters

Should configuration with the Easy Setup menu not be enough to meet your needs, you will have to

calibrate your instrument and enter specific values to perform this calibration. The following pages

explain how to do this.

Level calibration parameters are set under the Calibrate menu. Figure 39 illustrates these parameters

Figure 38 The Calibrate menu

This value (probably set initially from the Easy Setup menu) represents the lowest level measurement

value in your vessel.

To set that value:

1 Select Calibrate > Level Calibration > Empty/Zero.

2 Press Edit.

3 Set the value as necessary and press OK.

By default, the empty/zero value is linked to the 4 mA value.

NOTICE

Make sure that the empty value is less than or equal to the full value.
