SECTION 7 TROUBLESHOOTING
7.1 ERROR MESSAGES
The instrument performs a Power On Self Test each time it is turned on. The following error
messages are provided to facilitate troubleshooting. They appear on the bottom line of the LCD
when an error is detected.
TEMP OUT OF COMPENSATION RANGE
The unit is configured to use a non-linear temperature compensation curve (either measured or
pre-stored). The current measurement temperature is outside the limits of the temperature
compensation curve. i.e. a user records a temp compensation curve from 15 to 45°C. This error
will be displayed if they then measure a sample below 15°C or above 45°C.
REF TEMP OUT OF RANGE
The unit is configured to use a non-linear temperature compensation curve (either measured or
pre-stored). The current reference temperature is outside the limits of the temperature
compensation curve. i.e. a user records a temp compensation curve from 15 to 45°C. This error
will be displayed if they then set the reference temperature below 15°C or above 45°C.
NO TEMPERATURE INPUT
The system is configured to use a form of temperature compensation but no temperature probe is
connected. To temperature compensate either a conductivity cell with integrated temperature
probe or a separate temperature probe is required.
TEMPERATURE COMP OVERRUN
The current configuration along with current measured temperature has produced a temperature
compensation of more than 5 times the reading (500%) or less than 1/10 the reading (10%). The
instrument will not read correctly with temp comp beyond this range. Example: Compensation is
set to 10.0%/°C at 0°C while the current temperature is 100°C.
OUT OF RANGE
In manual ranging mode. The currently selected conductance range is reading outside its limit.
ALARM! READINGS OUT OF LIMITS
This is NOT an error. The user has enabled the alarm and the current reading has triggered the
alarm. See 3.5 Display Configuration, Alarms.
