5.2 PRELIMINARY CALIBRATION CHECKS/PROCEDURES
A Objectives
When you have completed this topic, you will be able to:
B Do the preliminary calibration checks and procedures.
B References
In the Online Help System or the Instructions for Use manual, refer to Heading 10.2
PRE-CALIBRATION CHECKS
.
C Special Instructions
1. The instrument must be powered up.
2. If possible, do this topic when calibration is needed.
D Topic Notes and Tasks
1. The preliminary calibration checks and procedures are designed to ensure the
instrument is clean and operating optimally.
2. As a matter of precaution it is a good idea to thoroughly review the data stored in current
control files, the XB/XM files, if applicable, and the IQAP data.
a. Make sure that none of the data points to an instrument problem as opposed to a
calibration problem.
b. Note any possible biases that might require a change in a calibration factor.
3. Before beginning the calibration procedure you should:
a. Verify the ambient room temperature is typical for the laboratory and within the
instrument’s operating range (16 to 34°C; 61 to 93°F).
The temperature specifications are listed under
Heading 3.1, INSTRUMENT
SPECIFICATIONS,
in the Online Help System or the Instructions for Use manual.
b. Ensure all reagent levels are adequate for calibration.
c. Ensure the waste container has sufficient space for waste collected during
calibration.
d. If the instrument is not routinely shut down with Rinse reagent for at least
30 minutes every 24 hours the instrument is in use, do the Extended Cleaning
procedure to ensure the Analyzer, particularly the apertures and baths, are clean.
e. Do a Startup procedure.
f. Run a commercial cell control.
4. Have the trainee locate
Heading 10.2, PRE-CALIBRATION CHECKS, in the Online Help System
or the Instructions for Use manual, and have them do the checks if calibration is
scheduled.
