Real Time Data
When the DataFID is being used in conjunction with a Computer or a PDA, the current TVOC
reading can be sent to a PDA only if the Real Time Data option is ON. The Real Time Data
function is used to switch on and off the Bluetooth message transmission. To switch the
Bluetooth messaging to the PDA on and off:
1. From the Main Menu display, select the “DataFID Setup” option.
2. Select the Real Time Data option and then press the SELECT soft key. Press the DOWN
ARROW soft key to either turn the Bluetooth messaging to the Computer/PDA on or off.
3. Press SELECT soft key to return to the DataFID Setup menu display.
Compound Selection and Response Factors
The response of a flame ionization detector to a compound is dependent on its ionization
potential. In certain situations when the user is confident that only a single specific compound
exists, they can set up the DataFID using a Methane, Hexane, or Propane calibration to mimic
the DataFID response as if the DataFID was calibrated using that specific single compound.
The DataFID ’s 6 memory slots can be used to store compound information for 6 different gases.
A 7
th
memory slot exists as Memory Slot 1 but it is reserved for TVOC and its default settings
are that of Methane. The TVOC slot appears when this option is selected. The TVOC memory
slot 1 appears with the Compound name as a blank, Response Factor set to 1.0, Alarm Level
set to 1000.0, and a Formula Weight of 16.0.
The DataFID ’s other 6 memory slots can be used to store compound information for 6 different
gases. By using the Up and Down arrow soft keys, the current values for these compounds can
be viewed one at a time. When the desired compound appears on the screen, the select soft
key can be used to choose that compound and its associated parameters (Response Factor,
Alarm Level, Formula Weight) as the active compound in which all measurements are
performed. See Figure 30.

Select Calibration Gas
There are three Gas types of which any one can be used to perform a DataFID calibration. On
selecting ‘Select Cal Gas’, the three calibration type gases will appear as a list. They are
Methane, Propane, and Hexane. Using either the Up or Down arrow soft key, highlight the
desired calibration gas and use the SELECT soft key to set the gas.
Compound:
Resp Factor: 1.0
Alarm Level: 1000.0
