Setting up a
humidity isotherm
Follow this procedure to set up an isotherm color that is displayed when the camera
detects an area where there may be a risk of humidity in a building structure:
Push the Measure button.1
On the menu, select Detect humidity.2
Push the joystick twice.3
Use the joystick to set the following parameters:
■
Rel. humidity limit: The critical limit of relative humidity that you want to
detect in a building structure. For example, mold will grow in areas where
the relative humidity is less than 100%, and you may want to find such
areas.
■
Rel. hum. limit: The current relative humidity at the inspection site.
■
Atm. temp.: The current atmospheric temperature at the inspection site.
4
Push the joystick to confirm each choice.5
Push the Measure button to leave the main menu. The screen will now
display an isotherm color when the relative humidity exceeds the set level.
6
Setting up an
insulation
isotherm
Follow this procedure to set up an isotherm color that is displayed when the camera
detects what may be an insulation deficiency in a wall:
1 Push the Measure button.
On the menu, select Detect insulation.2
Push the joystick twice.3
Use the joystick to set the following parameters:
■
Inside temp.: The temperature inside the building you are inspecting.
■
Outside temp.: The temperature outside the building you are inspecting.
■
Thermal index: The accepted energy loss through the wall. Different
building codes recommend different values, but typical values are 60–80
for new buildings. Refer to your national building code for recommenda-
tions.
4
Push the joystick to confirm each choice.5
Push the Measure button to leave the main menu. The screen will now
display an isotherm color when the the camera detects an area with an
energy loss higher than the set value.
