selected gas span level (if ozonator and permeation oven are both off),
permeation oven and ozonator levels, time, and alarm status. There are 5
values that may be displayed on the run screen that include the following:
TFLOW (total flow in sccm, as measured by the zero and gas flow
controllers)
GAS X
(dilution concentration of gas from selected tank in ppm, name is
user definable)
O3
(concentration of ozone measured by photometer in ppm)
PERM
(concentration from permeation tube in ppm)
GPT
(drive level of ozonator in GPT mode in percent)
If a particular option is not installed or not being used, it is removed from
the display. The example below shows the Model 146
