The steps above could be repeated for any of the 2 points if
additional fine adjustment is needed.
NOTICE: The order in which the points are set is irrelevant.
To exit the calibration menu press to scroll until either
point 00 or 01 is highlighted and then
to exit the
calibration and return to the previous menu.
Calibration examples
1 Use of validation rule for Level Calibration
In the examples below the Input span is 100 – 0 = 100cm, as
such Output span must be between 95 and 105 cm (‘Out’ values
range must be within 5% of the ‘In’ values range).
Examples of acceptable calibration:
Top Mount Case 1 Case 2 Case 3 Case 4
Point In Out Out Out Out
Examples of rejected calibration:
Bottom Mount Case 4 Case 5
Point In LVL LVL
2 Calibration moving float to both 0 and 100% points (Wet
Calibration)
Requirements
• Mounting: Bottom or Top
Procedure
• Capture sensor value (SVL) to assign it to <In> of
• End
3 Calibration moving float only to 0% point only (Partially Wet
calibration)
Conditions
• Mounting: Bottom or Top
Procedure
• Capture sensor value (SVL) assign it to <In> of point
mounted transmitters.
• End
4 Calibration stretching the zero beyond trim points
Conditions
• Mounting: Top
Procedure • Determine the lower point to measure.
• Place the float in that position and inspect the
signal in the waveform screen to make sure that
there is enough signal amplitude, that is not
merging with the end of the probe.
• Back off from that position until the signal is not
merging with the end of the probe and the
amplitude is the same as in the begining of the
probe
• Measure the distance from the desired zero mark.
• Set the measured distance for parameter <Out> of
• End
5 Calibration when float cannot be moved to 0% or 100%
points (Dry Calibration)
Conditions
• Mounting: Bottom or Top
Procedure
• Use the resulting sum for parameter <In> of point
• End
6 Changing mount orientation
Conditions
• Mounting: Bottom or Top
• Previously calibrated for specific mount
