BASIC ANALYZER FUNCTIONS
Analyzer Batteries
Your carbon monoxide analyzer is fitted with three AA size 1.5V alkaline bat-
teries. It is important to keep battery power to the sensors in your analyzer
even when it is not in use.
Your analyzer has a battery status indicator in the lower right corner of the
display. Battery status is determined as follows:
Indicates batteries are at full capacity.
Indicates batteries are at 2/3 capacity.
Indicates batteries are at 1/3 capacity. Replacement of batteries
should be considered soon.
Indicates batteries are very low and in need of replacement
immediately. See Appendix H for battery replacement instructions.
Turning The Analyzer On
Always:
-
Before turning on please ensure that the Mini Pump Protection
Filter assembly the Tubing & In-Line Filter are not connected to the Gas
Sample Port (see page 7)
The instrument MUST be turned on in a clean air environment as the initial
purge will set the Carbon Monoxide level to Zero. Press and hold down the
Power Key and the TPI 707 will start its 30 second countdown 'PURGE' will
be displayed.
After start up, several tests can be performed to ensure proper function of
the analyzer and flue probe. Please refer to Appendix A.
After the 30 second countdown the instrument is ready to take carbon
monoxide readings.
The 707 will auto power off if no keys have been pressed for 10 minutes and
the CO level is below 15ppm. Auto off can be disabled (see Appendix D). The
auto power off feature is always enabled upon power up.
Turning The Analyzer Off
Always: - Before turning off return the instrument to a clean air environment
and allow the Carbon Monoxide level to return to below 15ppm. Press the
Power Key to turn the instrument off:- NOTE Should you attempt to turn the
instrument Off and the CO reading is above 15ppm 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 15ppm
The instrument has an auto shut off after 10 minutes should no keys have
been pressed for this period and as mentioned above that the CO is below
15ppm. Should the CO be above 15ppm then the 10 minute auto shut off
countdown will not begin till the CO has gone below 15ppm. The auto power
off feature can be disabled. Please see Appendix D. The auto power off fea-
ture is always enabled upon power up.
Activating the Backlight
The display backlight can be activated at any time by pressing and holding
down the Func Key for approximately 2 seconds. The backlight will automati-
cally shut off after approximately 20 seconds to preserve battery life.
