7.4 Setting Detector model
The default detector model set before shipment from the factory is ZR22G. If you plan
to use the "ZO21D
*
" then before starting warmup you need to change the default
setting. If you do not change the setting before starting warmup then detector tempera-
ture control will not work properly and serious damage to the detector may result.
There are two ways of changing this setting before warmup, as follows:
