To help position the flue gas probe in the centre of the flow (area of the
highest flue gas temperature), the flue gas temperature measured is
shown graphically.
Do not measure for longer than 5 minutes, as the readings may fall
outside of the tolerances due to a possible drift of the pressure sensor.

mpp.. function: The differential temperature set (0554 1208)
must be connected. The ambient air sensor must be unplugged (located
bottom left of unit) before connecting the T1 sensor. Be aware that the
connector is a firm fit, when disconnecting.
The differential temperature is calculated from T1 - T2.
D
Diiffff--pprreessss function: The gas pressure set (0554 1203) must be connected.
The pressure sensors are zeroed when the D

(length of time: 5 s). The measuring instrument must not be pressurised
during zeroing!
Do not measure for longer than 5 min, as a drift of the pressure sensor
may result in readings outside the tolerance limits.
