4.2.4.2. Initiating a GPT Pre-Set

Make sure that
the T700 is in
STANDBY
mode
Toggle these buttons

concentration.
MUST be at least 10%
Higher than the Target
O Concentration

Toggle these buttons to
set the target TOTAL
FLOW.
(Default = 2.000 LPM)

To activate the GPTPS feature you will need to know:

The TOTAL GAS FLOW for the mixture output;

The Target O concentration (equal to the target NO
3
simulated), and;

The NO source gas concentration.
Then, press:
