– Press ⇑ or ⇓. The display switches to the current measured sensor value in counts.
– Press ⇑ or ⇓ to enter Edit Mode; the sensor value is frozen and ready for editing.
– Set the sensor value to 105% of the value obtained in step 2d (1.05 x counts). Press ⇑
– After editing the least significant digit (or leaving it unchanged), press ⇓ to terminate
– Press M to exit.
3. Determine the switch point:
– Bring the process material to the desired switching level in the process.
– Record the count value displayed on the device.
– Calculate the trip point as a percent of process range:
4. Adjust the On to Off switch point (Mode 25):
– Use the M button to navigate to Mode 25.
– Set the value to 5% above the trip point percentage calculated in step 3c as a starting
5. Adjust the On to Off switch point (Mode 26):
– Use the M button to navigate to Mode 26.
– Set the value to 5% below the trip point percentage calculated in step 3c as a starting
6. Adjust the other parameters of the device as desired.

point.
Note
• A hysteresis (difference between the Off to On switch point and the On to Off
switch point) of 10% is used as an example of a typical setup. In some situations it
may be desirable to increase the hysteresis between the two switch points to
prevent false tripping (e.g. turbulence in the process).
• All parameters should be set up to account for a possible deviation of ±1% of the
actual measurement under reference conditions.
