4.3.3 Printer
Thermal polyester or thermal paper. Thermal polyester cannot be altered and it is resistant to light, temperature,
humidity and water.
The print menu is accessed by pressing the relative key and, besides enabling read-out printing, the menu also
allows you to modify print settings and to feed the paper manually for paper roll replacement.
4.3.4 B-Type USB connector
Connector to connect the device to a personal computer or to the battery charger.
The device comes with a feeder with output 5V=, 2A to charge the internal batteries. In (section 4.3) you can
see the socket to connect the battery charger to the device. Once it has started charging, the display turns on
and the charging state is displayed.
4.3.5 Serial connector (Mini Din 8-pole)
In (section 4.3) we find the socket of the serial cable for connecting the instrument to an external probe, for
example, to the draft gauge (optional), or to the ionisation current probe (optional).
4.3.6 Pneumatic connector inputs / TC-K
Pneumatic connector " A ": input for the connection of the branch of the gas sampling probe with the
condensation separating and anti-dust filter assembly.
Pneumatic connector " P- ": negative input (P-) to be used in case of differential pressure measurements
together with P+ input.
Pneumatic connector " P+ ": positive input (P+) to be used to measure the pressure in general and for
tightness tests. It must be connected to the second branch of the gas sampling
probe in order to measure the draft and analyse combustion at the same time.
WARNING: the inputs "P+" and "P-" are respectively the positive and the negative inputs of the internal
differential pressure sensor, therefore they are used simultaneously to measure the differential pressure.
Female connector TC-K " T1 ": input for the connection of the male TC-K connector of the gas sampling probe.
Female connector TC-K " T2 ": input for the connection of the male TC-K connector of the combustion air
temperature probe.
