Calibration
The calibration of the mA output may be done such
that its span will be either proportional or inversely
proportional to the material level.
Calibration: Reference Method
4 mA calibration
20 mA calibration
Operation Status
The graphic portion of the display gives the user a visual
indication of The Probe's operating status. Viewing the
graphic can assist the user in properly locating and
installing The Probe to achieve optimum performance.

• 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.

Calibration bypasses the measurement response rate.
Note:
The logo will change from full to partial to indicate operation status. After the `Waiting' period, the `?'
icon will appear for an `LOE / FAULT' indication. When a valid echo is again received, a `Good'
indication will resume. Refer to Troubleshooting on page 9 .
