Parameter Function
Analyzer rate
The analyzer rate is the saving cycle for mean
values. It is programmed in units of seconds,
minutes, whereby the smallest possible analyzer
rate depends on the number and type of
connected probes.

6.2. Measuring
6.2.1. Preparing for measurement
The combustion air temperature is continuously measured
by the temperature sensor installed in the analyzer box.
The fresh air required for the zeroing phase is drawn in
through the exhaust if no fresh air valve (option) is installed
and through the valve inlet if a fresh air valve is installed.
The flue gas probe can thus already be inside the flue gas
channel before or during the zeroing phase.
The testo 350 can be operated as follows:
• lying down
• hanging horizontally down by its handle
• plugged vertically to the wall bracket by the handle
To prevent measuring errors the position of the testo 350
must not be changed during a measurement.
Under ambient temperatures of 50° F the CO
2
-(IR) sensor
requires a shorter heat-up time to reach full measuring
accuracy. At 23 °F this typically is 15 min.
