Operation
Switching
on By pressing the button you switch the analyser on. The sensors are
calibrated automatically. Make sure that the probe is not inserted into the flue gas
pipe and hold your analyser in fresh air.
On switch on, the analyser beeps 4 times and displays date, time and model
number. The countdown runs from 90 to 0 untill sensors are ready to use.
Through integral dynamic calibration the countdown might be finished within 20 -
30 seconds. Calibration will last longer as the analyser gets older or in case it
was overstressed with high CO concentration. If the repeated calibration was not
succesfull, sensors must be tested and, if necessary, replaced.
Note During calibration both temperature probes should be connected to the
device!
If the ambient air probe (T
2
) is connected to the analyser during the countdown,
this temperature probe is used for further measurements. In case any probe (for
example, flue gas probe) is connected to the analyser during countdown, the
temperature, measured by the flue gas probe will be used for further
measurements and calculations as T
2
. If no probe is connected, the analyser’s
internal ambient temperature sensor will be used untill the analyser is switched on
the next time.
Selecting
fuel type
Turn the rotary switch to the position MENU, press the buton twice, select
the required fuel type using the buttons , press confirm button and
turn the rotary switch to the required measuring program position.
Switching
off
By pressing the button you can switch your analyser off. The displays
counts down from 30 with the pump on to clean the sensors with fresh air. Make
sure that probe connected to the analyser is in fresh air.
Press the button to stop the countdown and return to the measuring mode.
Attention: BRIGON 500 NT will switched off only when the CO reading is below 20
ppm. If the CO reading is higher, the analyser displays CO HIGH and flush the
sensor further.
Navigation
Use the buttons to change the settings, to navigate in MENU, to
switch between the measuring windows, to zero the pressure sensor and to
choose the display order.
Take care that the buttons must be pressed shortly or longer to perform certain
functions in different measuring programs.
