Non-Volatile Memory Error
There is a problem with either the display electronics or the main
board memory.
1. Power the analyzer down, wait for 10 seconds and power
back up.
2. If the error persists, contact your local ABB representative.
Calibration Factor Too High / Low
A secondary calibration failure has occurred because the calibration
factor is less than or greater than the acceptable limit programmed.
1. On the 'Calibration' page, check that the secondary
calibration value has been entered correctly.
2. Remake the secondary standard. Use a higher value solution
if possible, as this is easier to make with less chance of
errors.
3. Replace the reagents with a fresh batch, especially if this
message appears after the first calibration following the
reagent replacement (applicable to low calibration factor
only).
Reaction Block Temp Stabilizing
This message is displayed at startup and remains until the reaction
block temperature has stabilized to within 2 ºC (3.6 ºF) of the
programmed control temperature. If the message is still displayed
after 15 minutes:
1. Check that the sample and ambient temperatures are within
the quoted limits.
2. Check the 'Heater' value displayed on the 'Measurement
Status' page within 'Diagnostic Information' – see
Section 12.3, page 60.
If the temperature is low, check the heater LED on the main board is
lit. If it is not, contact your local ABB representative.
Reaction Block Temp. High / Low
>2 °C (3.6 °F) but <20 °C (36 °F) above or below
The measured temperature is more than 2 °C (3.6 °F) but less
than 20 °C (36 °F) above or below the programmed control
temperature.
1. Check that both the sample and ambient temperature are
within the quoted limits.
2. If the error persists, contact your local ABB representative.
