SECTION 6 - CALIBRATE MODE
INTRODUCTION
The Calibrate Mode of Operation provides the
ability to calibrate the sensor input,
temperature input, and analyzer outputs.
These functions (i.e., Calibrate States of
Operation) include process variable,
temperature, edit, reset, and output
calibration.
CALIBRATE STATES OF OPERATION
The Calibrate Mode consists of six states of
operation. Table 6-1 describes the function
of each state of operation.
Table 6-1. Calibrate States
State Function
PH.CAL Used to calibrate the input from
ORP.CAL the process sensor using a one-
ION.CAL point offset or two-point
offset/efficiency calibration.
TMP.CAL Used to calibrate the input from
the temperature sensor using a
one-point smart calibration that
adjusts the offset, slope, or both
based on sensor calibration
history.
EDT.CAL Used to manually adjust the
process sensor offset and
efficiency and temperature sensor
offset and slope values.
RST.CAL Used to restore calibration values
for the process variable and
temperature back to factory
settings.
AO1.CAL Used to calibrate Analog Output
One. Requires an external
validation device.
AO2.CAL Used to calibrate Analog Output
Two. Requires an external
validation device.
When in the Calibrate Mode, the NEXT Smart Key
provides access to all Calibrate States.
Pressing the NEXT Smart Key sequentially moves
the user through each Calibrate State. This
cycle repeats until a Calibrate State is
selected using the SELECT Smart Key, or the
