BASIC ANALYZER FUNCTIONS
Charging The Analyzer
Plug the charger into the charger socket on the instrument (see page 8). If
the instrument is turned on then a charging symbol will be displayed. When
the analyzer is off the charging symbol will not be displayed BUT the instru-
ment will still be charging.
The instrument should be charged overnight for a period of 10 to 12 hours
and will give over 6 hours Operating Time. If a beeping noise is heard during
charging disconnect the charger. This is an indication the battery pack needs
to be replaced. Please see Appendix J for battery replacement instructions.
The 712 can be used while plugged into the charger even without a battery
installed.
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. The analyzer should be con-
nected to the charger soon.
Indicates batteries are very low and in need of recharge immediate-
ly. Connect the charger to the analyzer.
Indicates the analyzer is connected to the charger. This symbol is
only seen if the analyzer is on and running while connected to the
charger.
If the analyzer will no longer charge to full capacity or if a beeping noise is
heard during charging this can be an indication the battery pack needs to be
replaced. Please refer to Appendix J for battery pack replacement instruc-
tions.

Turning The Analyzer On & Fuel Type Selection
Always:
-
Before turning on please ensure that the Mini Pump Protection
Filter assembly and the Temperature Sampling Probe complete with In-
Line Filter or the Tubing & In-Line Filter for Leak Detection are not con-
nected 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 and the Oxygen to 20.9%.
Press and hold down the Power Key and the TPI 712 will start its 30 second
countdown 'PURGE' will be displayed.
During the last 20 seconds of the 30 second purge time the type of fuel can
be selected. Use the Up Arrow key to scroll through the following Fuels: -
Natural Gas, LPG, Light Oil*, Heavy Oil*, OPT1 : Bituminous Coal, OPT 2 :
Anthracite Coal, OPT 3: Coke, OPT 4: Butane, OPT 5: Wood (Dry), OPT 6:
Bagasse. When the desired fuel is displayed release the key and the displayed
fuel is now selected.
Unless a fuel is selected the analyzer will start up using the last fuel selected.
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 Flue,
Temperature, Pressure or Leak Detection readings and the default combus-
tion display will be displayed.
The 712 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.
The Scroll/Enter Key allows you to scroll through the combustion displays as
outlined on pages 17&18. The Func Key is used to select the 712 function
mode and allows you to set it to be a combustion analyzer, manometer, ther-
mometer, or combustible leak detector. In addition, the Func Key is used to
access the date and time display. See pages 20 through 24 for more informa-
tion on the Func Key.
*NOTE: When selecting oil as fuel be sure to use the optional
oil filter (A773) or readings could become erratic. See
Appendix E for installation instructions.
