3.1 Turning On
Always
: -
Before turning on please ensure
that the
In-Line Pump Protection Filter
(shown across) is connected to the Gas
Sample Port (see 2.2 or 2.4).
**THIS MUST REMAIN ON THE UNIT
AT ALL TIMES.**
Failure to do so may result in pump failure
and will invalidate the warranty.
Press the
Power Key
for approximately 2 seconds and the TPI 712 will start
up and display ALL Segments on the display for approx. 1 second. The 712 will
then enter its 30-second purge period countdown with the following screen being
displayed.
The instrument should ALWAYS be turned on
in a clean air environment as the 30 second
purge will attempt to set the Carbon Monoxide
level to 0 ppm and the Oxygen to 20.9%.
If there is insufficient clean air in the sensor
chamber after the 30 second purge period an
error indicating this may be displayed, please
see troubleshooting guide (appendix D) for
appropriate remedy. If the error is still present
after attempting the suggested remedy please
call the
TPI HELPLINE
