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
Field Safety System™
continuously records the readings from the sensor and stores the minimum and maximum (MAX/MIN,
peak hold) values in non-volatile memory. The max/min values may be viewed at any time by removing the enclosure cover (page 5) and pushing
the left
2
button. The display will scroll the MAX/MIN values and then return to the Process Display mode.
To reset the values, enter the Programming Mode (see page 10). 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 10), the values will be reset to the
current reading and begin recording again.
