MESSAGE
DESCRIPTION
POSSIBLE CORRECTION
Max is 200
Entry failed, maximum user value allowed is 200. Reduce value to
≤
200
Min is 20
Entry failed, minimum value allowed is 20.
Increase value to
≥
20
Cal Unstable
Calibration problem, data too unstable to
calibrate. Icons will not stop flashing if data is too
unstable. User can bypass by pressing ENTER.
Clean sensor, get fresh cal solutions, allow
temperature and conductivity readings to fully
stabilize, do not handle sensor or cable during
calibration.
Out of Range
Input value is outside selected range of the
specific list item being configured.
Check manual for limits of the function to be
configured.
Locked!
Analyzer security setting is locked.
Enter security code to allow modifications to
settings.
Unlocked!
Analyzer security has just been unlocked.
Displayed just after security code has been
entered.
Offset High
The sensor zero offset point is out of the
acceptable range of -25 to +25 nA.
Check wiring connections to sensor. Allow
sensor to operate powered a minimum of 12
hours prior to first zero cal.
Sensor High
The raw signal from the sensor is too high and
out of instrument range.
Check wiring connections to sensor.
Sensor Low
The raw signal from the sensor is too low.
Check wiring connections to sensor.
Chlor High
The chlorine reading is greater than the
maximum of the User-selected range.
The chlorine reading is over operating limits.
Set measuring range to the next highest level.
Temp High
The temperature reading is > 55ºC.
The temperature reading is over operating
limits. Check wiring and expected temp level.
Perform RTD test as described in sensor
manual. Recalibrate sensor temperature
element if necessary.
