the serial menu is accessed, the instrument is no longer making measurements; it is waiting for the next 
command to be entered. The following is the list of menu items accessible from this point:

REL2  can  operate  as  an  ON/OFF  limit  switch,  as  described  in  the 

Configuration

  section,  above. 

Alternatively,  REL2 can  be set  to operate when certain diagnostic tests have failed (cell temperature, 
cell pressure, flow rate, photodiode voltage). The following are related commands that can be set from 
the serial menu:  

o

  Change relay 2 operation for temperature, pressure, flow, and photodiode voltage 

q

  Change relay 2 operation for ozone 

1

  Enable temperature inclusion for relay 2 

!

 

Disable temperature inclusion for relay 2 

2

  Enable pressure inclusion for relay 2 

@

  Disable pressure inclusion for relay 2 

3

  Enable flow inclusion for relay 2 

#

  Disable flow inclusion for relay 2 

4

  Enable pdv inclusion for relay 2 

$

  Disable pdv inclusion for relay 2 

Indicates the enable/disable status of the diagnostic tests

   

The limits for each of the diagnostic tests are listed below: 

Temperature   

LOW: 5 

HIGH: 50 

Pressure 

 

LOW: 500 

HIGH: 1100 

Flow   

 

LOW: 400 

HIGH: 2000 

Photodiode Voltage  LOW: 0.6 

HIGH: 2.45
