Required Equipment
T able 1-1 lists the equipment required to perform the A djustments and the Correction Constants
procedures described in this chapter . Use only calibrated test equipment when adjusting the
analyzer . If the recommended test equipment is not available , equipment whose specications
are equal to , or surpasses those of the recommended test equipment may be used.
W arm-up for A djustments and Correction Constants
W arm-up the analyzer for at least 30 minute before performing any of the following
A djustments and Correction Constants procedures to ensure proper results and correct
instrument operation.
Instrument Cover Removal
T o gain access to the adjustment components , you need to remove the top cover and the side
covers .
