• Press the right
g
button to view and change deadband. Press the left
2
button to increment the blinking digit. Press the right
g
button to
enter and move to the next digit.
• Press the right
g
button to enter a new Deadband. SW1 will show on the display.
NOTE:
The Set Point and Deadband settings are subject to the accuracy of the instrument. Actual switch points may vary up to +0.5% of the
sensor’s maximum range at room temperature. Example: The P15 sensor has a range of 0 to 300 psi. When setting a Set Point of 150, the
actual switch point may occur between 148.5 and 151.5 due to the accuracy error of +1.5 (300 x 0.5%).

Resetting the Maximum & Minimum Values
The One Series continuously captures the readings from the sensor and stores one minimum and maximum value since the last time they were
reset. The values can be viewed at any time by removing the enclosure cover and pushing the left
2
button. The display will scroll the values and
then return to the Process Display mode.
To reset the values, enter the Programming Mode (see page 9). Repeatedly press the left
2
button to get to the CLR MAX/MIN command and then
press the right
g
button two times. After exiting the Programming Mode and saving the changes (see page 9), the values will be reset to the cur-
rent reading and begin recording again.
