There are several operating adjustments that can be made to The Probe.
• Press the "4" and "20" keys simultaneously until the desired adjustment is obtained. A viewing
sequence of the stored value is automatically initiated.

The 4 and 20 mA calibration values can be selected where reference levels, either from the material
in the vessel or from a target, cannot be provided. This method can also be used to trim the output
levels obtained by the Reference Method (see page 4).
• To change the stored calibration value, obtain the `c 4' or `c 20' display.
• Press the "20" key to increase or the "4" key to decrease the calibration value.
• After scrolling to the desired value, stop pressing the key. The display automatically reverts to the
Run mode (6 sec).
