10 Maintenance 10 Maintenance 10.1 Service Testo recommends an annual check of the testo 300 which can be performed by a service center authorized by Testo. Please contact Fr d 10.2 Calibration The measuring instrument is supplied with a calibration protocol as standard.
10 Maintenance 10.4 Clean the measuring instrument > If the housing of the measuring instrument is dirty, clean it with a damp cloth. Use distilled water, or alternatively mild solvents, such as isopropanol, to clean the flue gas analyzer. CAUTION Improper use of isopropanol! Irritation of the eyes and sensitive mucous membranes! Fumes have a slight narcotic effect!
Page 62
10 Maintenance CAUTION Weak mix of acids in the condensate! Minor injuries! - Avoid skin contact. - Make sure that the condensate does not run over the housing. CAUTION Condensate entering the gas path! Damage to sensors and flue gas pump! - Do not empty condensate trap while the flue gas pump is in operation.
10 Maintenance 10.6 Open the measuring instrument Only open the measuring instrument when this is required for maintenance purposes (replacing gas sensors). The measuring instrument must not be connected to a mains socket via the mains unit. The measuring instrument must be turned off. When opening/assembling the instrument, take care not to lose any screws that have been removed.
10 Maintenance Place the instrument on its front again. Remove the remaining four screws on the back of the instrument. Lift off the back of the instrument. Assembly Perform in reverse order to assemble. Please note: - Lay hoses and lines in the guides intended for this purpose. - Make sure that hoses and lines do not get jammed.
10 Maintenance 10.7.1 Replace O2 sensor Measuring instrument is open, see Section Open measuring instrument. Unlock retaining bracket and open out. Remove faulty sensor from the slot. Insert new sensor in the slot. Make sure that the socket on the sensor circuit board is correctly connected to the contact plug.
10 Maintenance 10.7.2 Change CO, CO H2 and NO sensor Measuring instrument is open, see Section Open measuring instrument. Remove faulty sensor and hose connections from the slot. Remove hose connections from the faulty sensor/bridge. For NO sensor: Remove auxiliary circuit board. Do not remove the auxiliary circuit board of the NO sensor until immediately before installation.
10 Maintenance 10.8 Clean modular flue gas probe Disconnect flue gas probe from the measuring instrument. Release probe catch by pressing the key on the probe handle and remove probe module. Blow compressed air through flue gas ducts of the probe module and probe handle (see illustration).
Page 68
10 Maintenance Replace particle filter The filter chamber may contain condensate. This is not a malfunction and will not cause incorrect readings. Open filter chamber: turn slightly counter-clockwise. Remove filter chamber. Remove filter plate and replace it with a new one (0554 3385). Attach the filter chamber and lock it: turn slightly clockwise.
10 Maintenance 10.11 Replace thermocouple Release probe catch by pressing the key on the probe handle and remove probe module. Remove thermocouple plug-in head from the socket using a screwdriver and pull thermocouple out of the probe shaft. Insert new thermocouple into the probe shaft until the plug-in head clicks into place.
