3. Turning On &Off
3.1 Turning On
Always: - Before turning on please ensure that the Temperature Sampling Probe complete with InLine Filter is not connected to the Gas Sample Port (see 2.2 or 2.4)
Press the Power Key and the TPI 715 will start its 30 second countdown purge ‘PURGING’ will be
displayed: - The instrument should be turned on in a clean air environment as the 30 second purge
will set the Carbon Monoxide level to Zero and the Oxygen to 20.9%.
Ensure that the filters are clean and dry as dirty or wet filters will result in a loss of flow rate and ‘Lo
Flo’ will be displayed to inform you that filters should be changed
During the last 20 seconds of the 30 second purge time the user can scroll through the following
Fuels: - Natural Gas, LPG, Light Oil, Heavy Oil, Bituminous Coal, Anthracite Coal, Coke, Butane,
Wood (Dry), and Bagasse by pressing the Up Arrow Key to select the Fuel they are working with.
When desired fuel is displayed release the key, displayed fuel is now selected.

Wood (Dry) Fuel , OPT 5 Wood (Dry)
Bagasse Fuel , OPT 6 Bagasse
NOTE: When selecting oil
as fuel be sure to use the
optional oil filter to prolong
the life of the sensors.
After the 30 second countdown the instrument is ready to take Flue, Temperature readings and will
Display Screen 1 from Function 1 as described in The 3 Functions Section (see 4.1.1)
3.2 Turning Off
Always: - Before turning off return the instrument to a clean air environment and allow the Carbon
Monoxide level to return to below 15ppm and the Oxygen level to return to 20.9% (± 0.3%)
Press the Power Key to turn the instrument off:- NOTE Should you attempt to turn the instrument
Off and the CO reading is above 0.003% then the instrument will remain On and a short Beep will
be heard. The Instrument can only be switched off if the CO is below 0.003%
The instrument has an auto shut off after 10mins should no keys have been pressed for
this period and as mentioned above that the CO is below 0.003%. Should the CO be above
0.003%then the 10 minute auto shut off countdown will not begin till the CO has gone below
0.003%

Trouble Shooting Guide
Problem Solution
Unit will not turn on Battery voltage is low, change batteries.
Unit will not turn off The CO level is above 0.030% and the failsafe will not
allow the unit to shut off, wait for CO levels to drop and
then shut off.
Can not print saved readings -Make sure the infrared eyes are aligned on the printer
and the 715
-Make sure the lights on the printer are not flashing if
so batteries need to be replaced
Wrong readings are on the printout -Make sure you are selecting the correct location to
print, if saved in “location 1” print “location 1”
-Make sure you are not selecting REAL time print mode
