1.2 Fyrite® INSIGHT Features & Benets
AUTO/MANUAL ZERO - In automatic mode, the instrument automati-
cally zeroes all sensing channels on ambient air when it is powered on. If
a particular sensor is in error during warm-up, the instrument automati-
cally displays the error and continues to operate with the sensor in er-
ror. However, all information dependent on the sensor in error will not
be presented. When the CO channel is set to manual zero, the analyzer
does not zero the CO sensor to ambient conditions during start up. In this
mode, the “fresh air zero” established during manual mode setup is stored
in memory and used during the measurement of CO.
TEMPERATURE AND PRESSURE UNITS - Temperatures can be
displayed in Centigrade or Fahrenheit. Pressures can be displayed in mil-
liBar (mB), Pascal (Pa), hectoPascal (hPa), Millimeters of Water Column
(mmwc), or Inches of Water Column (inwc).
LANGUAGE - The display options are English, French or Spanish.
MEMORY - The Fyrite®INSIGHT has the ability to store, recall to dis-
play, and print a minimum of 100 sets of time and date coded combustion,
differential pressure, or differential temperature test records.
DOWNLOAD - Test records can be downloaded to a personal computer via
the USB port. Saved records are transferred using PC based software and
will be automatically loaded into an Excel spreadsheet. PC based software
will also have the capability to update the instrument time and date and
upload custom fuels, username, customer logo, and future code updates.
The INSIGHT can also be set up from PC software.

Instruction 0024-9460

Fyrite®INSIGHT
USER INFORMATION - The instrument will accept up to three lines of
20 characters of user information. This information will appear with the
test records when they are printed or downloaded.
CALIBRATION AND REMINDERS - Calibration can be performed by
applying gas and entering calibration gas concentrations through software
menu selections. Calibration reminders can be set for Never, 6, 8, 10, 12,
or 15 months.
SMART SENSORS - B-Smart sensor technology is employed for the CO
channel. CO sensors are calibrated prior to shipment and provide data that
can be entered through the software menu selections for easy calibration
without applying gas.
DISPLAY FORMAT AND ZOOM- The Run/Hold display format can be
presentedindefaultorcustomorderedforspecicneeds.Upto8lines
can be customized in the Run/Hold screen. Combustion test data in the
Run/Hold screens can be shown with enlarged characters to make viewing
easier. The complete list of Run/Hold data can be scrolled through for all
zoom levels. Available zoom levels and information display are as follows:
•Standard-4linesofinformation
•2X-3linesofenlargedcharacters
•3X-2linesofenlargedcharacters
STATUS - A status menu displays the instrument software version, boot
version, model number, and serial number.
DIAGNOSTICS - The diagnostics menu displays the O2 sensor life, CO
sensor information, and hours of operation (for the instrument and pump).
K EYPA D SOUND - Keypad sounds can be enabled or disabled with soft-
ware menu selections.
LOW BATTERY - A tone will sound every 10 seconds when a low battery
condition exists. A low battery message will also be displayed.
AUTOMATIC POWER DOWN - The instrument can be set to automati-
cally power off after a period of inactivity unless the user presses any but-
ton; the CO is greater than 50 ppm, or the O2 is less than 16.0%. Auto-
matic power down can be set for None, 30, or 60 minutes.
PURGE - The sensors will be purged when the instrument is shutdown
until sensor outputs indicate that they have been exposed to fresh air.
Pressing the On/Off key a seconds time can defeat the purge routine. The
minimum purge time can be set to None, 5 seconds, 1 , 5, or 10 minutes.

1.3 Operational Overview
Pressing the PWR button turns the analyzer ON. Note that there is a
warm-up period of 60 seconds that must elapse before the analyzer can be
used.
To perform a combustion test, choose a fuel code that corresponds to the
fuel being burned by the appliance being tested (Section 4.3), and then
press the RUN/HOLD button to place the analyzer into its Run Mode.
Begin testing by inserting the analyzer’s probe tube into the flue-gas
stream of the appliance under test. The analyzer will monitor the flue gas
and display measured and calculated values that are relative to the com-
bustion process. These values are displayed on the analyzer’s LCD, and
are chosen for display by pressing the Increment (▲)and Decrement (▼)
buttons. The recommended time required to achieve a stable measurement
is a minimum of 3 minutes.
Pressing the RUN/HOLD button during a test will freeze all measured and
calculated values at their current levels. Pressing the RUN/HOLD button
again resumes testing.
A backlight enables an operator to read the display in dimly-lit areas.
Pressing the PWR button turns the backlight ON and OFF.
An optional power saver function will shut the analyzer OFF after a set
time period of inactivity. This feature is disabled if the CO value is greater
than 50 ppm or the O2value is less than 16.0%.
Press the PWR button for at least two seconds to power the analyzer
OFF. Note that there is a 5 second delay before the analyzer actually
turns OFF, during which time the unit can be kept ON by pressing the
RUN/HOLD button. There is a CO purge feature that keeps the analyzer’s
pump running until the measured CO level drops below 50 ppm.
