Calibration
Calibration: Reference Method
• Adjust the material level (or target) to the desired distance from the sensor face.
• Press the “4” or “20” key (as appropriate) to view the stored distance associated with that mA
output value.
• Press the key a second time to set the new distance reference.
• After viewing or calibrating, Probe operation automatically reverts to the Run mode (6 sec). The
calibration value is referenced from the face of The Probe sensor, in the units displayed.

• With The Probe correctly installed (or
aimed at a wall 0.25 to 5 m away), apply
power.
• The Probe starts up displaying the
following:
program mode
alphanumeric
units
LOE / fault
operation status
‘4’ key
‘20’ key
• It then defaults to the Run mode, which is the measurement
reading of the distance from the transducer face to the
material level in the units indicated:
• If the default display differs from that shown, refer to
Operation Status on page 8.
The calibration of the mA output may be done such
that its span will be either proportional or inversely
proportional to the material level.
Note:
The 4 and 20 mA levels may be calibrated in
any order.
