4.2 Working sequence in a mode of measuring the differential pressure of air in the premis-
es with a special regime of air exchange (boost pressure measurements).
4.2.1 Place the device in the initial point and connect a hose to the upper end of the primary
converter sensor so that the side holes remained open.
4.2.2 Put the other hose end in a controlled area, the pressure differential in which (relative
to the initial point) should be measured.
4.2.3 Switch-on the device (move a toggle switch "on" in the upper position) and set the
measuring mode of the dynamic pressure (a jumper is attached on both connecting branches).
4.2.4 Push "I" button (once or withholding) to measure the pressure differential between the
initial point and the controlled area.
Attention! The differential pressure value measured in that way is indicated
with an opposite sign on a display, i.e. the excessive pressure (boost pres-
sure) with a minus sign, and a discharge one with a plus sign.
4.3 Working sequence in a temperature measurement mode.
4.3.1 Switch-on the device, put PCT in a place where temperature should be measured,
wait for the steady-state values on a display and read the temperature values.
4.4 When pushing "P" button once (click) the values indicated on a display are copied into
the device memory.
4.5 When pushing "0" and "P" buttons simultaneously in the mode of pressure differential
measurement the percentage of free memory is indicated on a display, when holding these buttons
the erasing of the information being kept is performed.
4.6 To read the results of the measurement from the memory it is necessary: to switch-off
the device, to disconnect the primary converter from the control unit, to connect a special adapter
(RS-232 interface) to the control unit, to connect the adapter to the computer, to switch-on the de-
vice and to read the device memory content.
