Rapidlab 1200 Operator's Guide: Troubleshooting
•
Check the solution level in the affected sensor and remove bubbles.
The K
should be completely full without any bubbles.
•
Check the sensor contacts and measurement block for salt buildup.
•
Check behind the sensors for fluid leaks that can come from the reference
sensor.
•
Check that the sensors are installed in the correct order and are aligned, the
O-rings are in place, and the spring-loaded latch is closed.
•
If the pH or Na
•
Check for cracks or leaks in the sample tubing, and replace the tubing if
necessary.
•
Replace the affected sensor, if necessary.
Using the Calibration Report to Identify Problems
The full calibration report shows the measurement and drift values. Rapidlab 1200
systems use a 2-point calibration curve. The two points on the curve are the Cal
Point and Slope Point.
•
The values in the Meas column represent the actual measured value of the
current calibration.
•
The values in the Drift column represent the difference between the measured
value from the current calibration and the value assigned to the analyte during
the manufacture of the cartridge.
•
If the system cannot report a value during a calibration, the result is blank on
the report and the D code and explanation prints at the bottom of the report
The following symbols can display with the results on the printed report.
