Scanning A Temperature Deviation; Example Of Application; Battery Indicator - Powerfix PTSI 9 A1 Bedienungsanleitung

Scanning a temperature deviation

♦ Press the measuring button
spot to be measured. The temperature is shown in the display
♦ While scanning, hold the measuring button
move the laser dot slowly and continuously over the surface
to be measured. The temperature deviations between the
reference and measurement values are presented as follows:
Colour
display
Red
Green
Blue

Example of application

For example, to check the penetration of cold air into an interior
through a window, fi rst scan the temperature around the frame
immediately adjacent to the closed window. Select the warmest
part of the frame as a reference temperature and then, for
example, a temperature diff erence of 3°C/5°F.
Now scan again, evenly, all around the frame directly next to the
window. A possible ingress of cold air of more than 3°K diff erence
is indicated by the blue colour display and by a slow signal tone
sequence.

Battery indicator

A battery icon appears in the display

♦ Insert a new battery as described in the section "Inserting/
Replacing the battery".
