[5.2 — Menu objects] N.B. – The screens on the following pages do not necessarily show possible com- binations of menu objects that can be displayed at the same time. They are only meant to show the operator the different types of menu objects. Figure 5.2 Menu objects –...
[5.3 — Menu area] Menu area The menu area is reached by pressing the ↵ button which activates the menu sys- tem. Moving the joystick left/right brings out the different pull-down menus. Select- ing an item in a pull-down menu is made by moving the joystick up/down. The selected item is highlighted.
[5.3.4 — Result table] The selected item is marked white/dark grey. Pressing the ↵ button normally con- firms the action (removing the dialog and confirm box) and puts the camera back in normal mode, i.e. focus/zoom. Pressing the C button removes the confirm box without any other action.
[5.3.9 — Critical information] 5.3.9 Critical information Critical camera information is displayed in the centre of the screen. Typical messages: Battery low The battery voltage is under a specified limit and the batteries will be empty within minutes. Battery empty The battery voltage has dropped below a minimum.
[5.4.4 — Naming files and directories in a PC] 5.4.4 Naming files and directories in a PC When creating directories in a PC there is no restriction on naming the directories. The camera can also read all directories on the root level independently of chosen directory name.
[5.5.1.3 — Periodic save…] 5.5.1.3 Periodic save… This function will save a number of images, at a certain selectable periodicity, onto the PC-card. Together with the images all the current conditions will be saved. When activating the function, a periodic save dialog will be displayed on the screen.
[5.5.1.6 — Delete image...] comments is stored on the PC-card (*.tcf). These text comments can be created and edited in AGEMA™ Report PC software. See the software Operator’s Manual for further information on creating and editing text comments. To add a text comment to an image, choose Text comments in the File menu. A dialog box with multiple choices of text comments appears on the screen.
[5.5.2 — Analysis menu] 5.5.2 Analysis menu In the analysis menu the desired measurement function can be activated. Isotherm can always be active along with one or more of the other functions, i.e. Area, Spot or Profile. If the multiple spots option is selected, the Analysis menu shows three different spot meters, Spot 1, Spot 2 and Spot 3.
[5.5.2.4 — Area] button to resume the normal function of the joystick, i.e. focus/zoom. To move the crosshair next time, it is necessary to confirm Spot (or Spot 1, 2 or 3) in the Anal- ysis menu. In Maximum (or Minimum) mode four corners of a box are displayed on the screen when the spotmeter function is activated.
[5.5.3.1.2 — Span] The whole temperature range is digitized and used for storage. However, normally only a small portion of the whole range is used for viewing. Select what tempera- ture to look at by adjusting level. The level function can be regarded as the brightness. 5.5.3.1.2 Span This function sets the span of the temperatures displayed in the image.
[5.5.4.1.3 — Area function] 5.5.4.1.3 Area function There are three different area measurement functions for the selected area type. They are Max, Min and Average. See “Area” on page 32. 5.5.4.1.4 Profile The profile measurement can either be displayed in a Vertical or Horizontal mode. See “Area”...
[5.5.4.2.4 — Saturation col.] 5.5.4.2.4 Saturation col. Saturation colour is an on/off function. If On is selected the areas that contain temperatures outside the present level/span settings are coloured with the satura- tion colours. The saturation colours contain an »overflow« colour and an »under- flow«...
[5.5.4.4.2 — Prompt comment?] Prompt comment ? 5.5.4.4.2 If this parameter is selected as Voice the Voice comment dialog box (see “Voice comment...” on page 26) will show up on the screen every time an image storage operation is made. This function gives the user a chance to add a voice comment to the image before storing the image on disk.
[6 — Battery system] Battery system The battery system consists of a removable battery and a fast charger. Figure 6.1 Battery & battery compartment. [1] Locking mechanism [2] Battery [3] Release button for battery [4] Hatch Battery The removable battery gives an operation time of about 2 hours per battery. When Battery low is shown in the camera it is time to change batteries by opening the hatch of the battery compartment on the back of the camera (see figure above).
[7 — Technical specifications] Technical specifications General specifications Object temperature measurement -40—+500 ºC (-40—+930 ºF), two ranges. Up to range (PM595): +2000 ºC (+2700 ºF) with high temperature option. Object temperature measurement -20—+500 ºC (-4—+930 ºF), two ranges.

[8.2.1 — Finding the emissivity of an object] 8.2.1 Finding the emissivity of an object 8.2.1.1 Using a thermocouple Select a reference point and measure its temperature using a thermocouple. Alter the emissivity until the temperature measured by the ThermaCAM™ PM575/595 agrees with the thermocouple reading.
[9.3 — Blackbody radiation] The relationships between the different wavelength measurements is 10 000 Å = 1 000 nm = 1µ = 1 µm Blackbody radiation A blackbody is defined as an object which absorbs all radiation that impinges on it at any wavelength.
[9.3.2 — Wien’s displacement law] 9.3.2 Wien’s displacement law By differentiating Planck’s formula with respect to λ , and finding the maximum, we have: 2898 λ ----------- - µm This is Wien’s formula, which expresses mathematically the common observation that colours vary from red to orange or yellow as the temperature of a thermal radi- ator increases.

[9.3.4 — Non-blackbody emitters] • The spectral transmittance τ = the ratio of the spectral radiant power transmit- λ ted through an object to that incident upon it. The sum of these three factors must always add up to the whole at any wave- length, so we have the relation: α...

[9.4 — Infrared semi-transparent materials] escapes; part of it is reflected back again. Although the progressive reflections become weaker and weaker they must all be added up when the total emittance of the plate is sought. When the resulting geometrical series is summed, the effec- tive emissivity of a semi-transparent plate is obtained as I ρ...
