G. Measuring This chapter describes the measuring tasks that can be carried out with the product. Familiarity with the contents of the chapter Operation (see p. 15) is assumed. Preparing measurements G.1.1 Zeroing phases Measuring the combustion air temperature (AT) If no combustion air temperature probe is connected, the temperature measured by the thermocouple of the flue gas probe or the connected external thermocouple at the probe socket during the zeroing phase is used as the combustion air temperature.
G.1.2 Using the modular ue gas probe Checking the thermocouple The thermocouple of the flue gas probe must not lie against the probe cage. Check before use. Bend the thermocou- ple back if necessary. Aligning the ue gas probe The flue gas must be able to flow freely past the thermo couple.
G.2 Measurements Before starting the measurement, remove and set aside the fitted sealing cap on the probe tip of the flue gas sampling probe. The sealing cap is required for the gas path check (see section E6).

H. Transferring data Protocol printer If data are to be transferred to a testo protocol printer via the infrared or Bluetooth inter- face, the printer that is to be used must be activated, see Printer, p. 28. Print Data are printed out via the function key .
Care and maintenance This chapter describes the steps and action required in order to keep the product functio- ning properly. See also Regular care, p. 18. Cleaning the measuring instrument If the housing of the instrument is dirty, clean it with a damp cloth. Use distilled water, or alternatively mild solvents such as isopropanol to clean the ue gas analyzer.
1 Place the measuring instrument on its front. 2 Loosen screws with a screwdriver, release clip in the direction of the arrow, and remove service cover. 3 Pull tube connections from the faulty sensor/bridge. 4 Remove the faulty sensor/bridge from the slot. Do not remove auxiliary circuit boards of the new sensors until immediately before ins- tallation.
I.4 Recalibrating sensors See Sensor settings, p. 31. Cleaning the modular ue gas probe Detach the flue gas probe from the measuring inst- rument before cleaning. 1 Release the probe catch by pressing the key on the probe handle and remove the probe module. Probe shafts with preliminary lter: Unscrew the preliminary lter.
