When the installed reagent module has less than 10% remaining, the
HOME MENU display will flash the % remaining. Prepare to install
a new reagent module when the % remaining reaches zero.
When all components are installed, confirm that the access door
is closed. WARMING UP appears at the bottom of the HOME
MENU display. When the sensor module reaches 37.0°C and the
valve module reaches 39.0°C (approximately 30 minutes from a cold
start) the WARMING UP message disappears. Calibration can now
be performed. Refer to Calibrate in Operating the Analyzer for further
instructions.
New electrodes require a short stabilization period to prevent drift
errors. This stabilization is minimized by the analyzer, which performs
calibrations every hour for 8 hours. After this stabilization period,
the analyzer will calibrate at the calibration frequency selected under
CAL FREQUENCY in the CONFIGURATION section of the
SETUP MENU.
