The controller may accept the value and show the
Sensor Calibrated screen.
If the value entered is too far from what the
controller has calculated as valid, based on the input
signal, a fault message will be displayed. Then you
will be given 3 choices on how to proceed.
Press
F1
to
RE_CAL
-
ibrate
the sensor [try again,
maybe you forgot to put the sensor in the buffer?…]
.
Press
F2
to
IGNORE
the fault and keep the current
calibration even though it is not generally advisable.
The controller will perform the math to make the
display match your entry. The ability to track
changes may be marginal or not possible if the
sensor is faulty.
Press
F3,
RESET
to cancel this calibration and return
to the previously saved calibration.
9.7 Calibrating an Amperometric Sensor
1- Press
the
CAL
key
2- Scroll down to the sensor you wish to
calibrate. Press
OK
3- Get a sample and run a DPD test. Use the
timer on the screen. Press
F1

the
MORE
button to reset the input to
factory default.
6- The controller should accept the value and

7- If the value you enter is too far from what the
controller has calculated as valid based on
the input signal, a sensor fault message will
be displayed.
If there is a Sensor fault:
Press either
F1
, RE-CAL to repeat the sensor
calibration.
Or press
F2
to ignore the fault and keep the current
calibration even though it is not generally advisable.
