Calibrating the T700 calibrator‟s optional internal photometer requires a different set up
than that used during the normal operation of the calibrator. There are two ways to
make the connections between these instruments and the T700 calibrator: either with
direct connections or calibration manifolds
Figure 7-3 shows the external zero air and O
photometer connected directly to the fixtures on the back of the T700 Calibrator.
