4.2.3.5. Initiating a GPT Calibration Gas Generation
Note
It is highly recommended to perform a GPT Pre-Set before initiating any GPT gas
generation (Section 4.2.4).
To initiate GPT gas generation you will need to know:
The TOTAL GAS FLOW for the mixture output;
The Target O
3
concentration (equal to the target NO
2
concentration to be
generated), and;
The NO source gas concentration.
Then, press:
EXIT discards the new gas type &
target concentration
ENTR accepts the new gas type &
target concentration
STANDBY GPT:0.0 PPB O3
