• 'Reflected Temp.'
The setting of this parameter can improve the measured result particularly in the case of materials
with low emissivity (= high reflection). In some situations (especially inside closed spaces) the reflected
temperature corresponds to the ambient temperature. If objects with strongly differing temperatures
in the vicinity of strongly reflective objects can influence measurement, you should adapt this value
accordingly.
7.5.2 'Display'
• 'Centerspot'
The spot is shown centered in the thermal image and shows you the measured temperature value at this
position.
• 'Hotspot': 'ON' ⁄ 'OFF'
The hottest spot (= measuring pixel) of the thermal image is marked by red crosshairs in the thermal
image. This makes it easier to search for critical places (e.g. loose contact terminal in the switchgear
cabinet). To obtain as accurate a measurement as possible, focus the object to be measured in the
center of the display (85 × 64 px). In this way the corresponding temperature value of this object to be
measured will also be shown.
• 'Coldspot': 'ON' ⁄ 'OFF'
The coldest spot (= measuring pixel) of the thermal image is marked by blue crosshairs in the thermal
image. This makes it easier to search for critical places (e.g. leak at the window). To obtain as accurate a
measurement as possible, focus the object to be measured in the center of the display (85 × 64 px).
• 'Color Scale': 'ON' ⁄ 'OFF'
This menu item lets you activate or deactivate the color scale.
'Average Temp.': 'ON' ⁄ 'OFF'
•
The average temperature is shown at the top left of the thermal image (average temperature across
all measured values in the thermal image). This can make it easier for you to determine the reflected
temperature
7.5.3 'Tool'
• 'Language'
Use this menu item to select the language used in the visualization.
• 'Unit'
This menu item lets you change the unit for the temperature reading between '°C' and '°F' (not applicable
for Japan).
'Time & Date'
•
To change time and date, navigate to the 'Time & Date' submenu. In this submenu, in addition to setting
time and date you can also change the corresponding display formats. To exit the 'Time' and 'Date'
submenu, press either the right function button to save the settings or the left function button to discard
the changes.
• 'Shutdown Time'
Use this menu item to select the time interval after which the measuring tool will automatically shut down
if no button is pressed. You can also deactivate automatic shutdown by selecting the 'Never' setting.
• 'High audio quality'
Use this menu item to adapt the quality of the recorded audio file via voice memo. Bear in mind that high
audio quality requires more space in memory.
• 'Tool Information'
Use this menu item to call up information about the measuring tool. You can view the serial number of
the measuring tool and see which software version is installed.
'Factory settings'
•
Use this menu item to reset the measuring tool to the default settings and irrevocably delete all data.
Under certain circumstances, this can take several minutes. Press the right button for 'More' to access
the submenu. Then either press the right function button to delete all files or press the left function button
to cancel the operation.
To exit any menu and return to the default display screen, you can also press the "Start/pause measurement"
button.
