Laser pointer active icon 14. Bluetooth® active icon NOTE Not all icons are represented in Figure 4–2. Other available icons are explained in their re- spective sections of this user manual.
When the Select button is pressed, six menu icons appear along the bot- tom of the MR277 display. Use the left/right navigation buttons to move to a menu icon, and use the Select button to open a selected menu. Once a menu is opened, the navigation and Select buttons are used to select modes of op- erations and settings.
Use the navigation buttons to move to the desired setting and then press Select to confirm. In Automatic mode, the MR277 automatically selects the temperature range for each thermal image, based on the highest and lowest temperatures de- tected. In Lock mode, you can ‘lock in’ a particular thermal image’s tempera- ture range and use this locked range for subsequent thermal image comparisons.

Thermal and Visible Camera Operation Figure 8.1 Color Palette options On the right side of the thermal images, a vertical bar graph provides a tem- perature scale for convenience. The top of the scale shows the hotter pixels in the frame, and the lower part of the scale shows the colder pixels. Digital readouts appear on the top and bottom of the bar graph to show the high and low range limits for the camera image.
Thermal and Visible Camera Operation Cross-hairs are visible when ‘Center Spot’ is selected from the ‘Measurement’ menu (Measurement mode). Cross-hairs are also visible in the ‘Custom IGM™ mode’ when ‘Radiometry’ is selected in the ‘Custom IGM™’ menu in the ‘Settings’ menu (Settings/Custom IGM™). 8.2 Automatic/Lock Temperature Scaling Note: For best results, allow a warm-up period of 3-5 minutes before using this feature.

9.1 Temperature & RH Measurements and Dew Point, Vapor Pressure, and Mixing Ratio Calculations The removable MR13 connects to the top of the MR277 and senses ambient Temperature and Relative Humidity. Calculations based on these Tempera- ture and Relative Humidity measurements are also provided. These calcula- tions are Dew Point Temperature, Vapor Pressure (in units of kilo-Pascals), and Mixing ratio (in Grains Per Pound).
9.2 Progressive Environmental Stability Indicator for RH% The Progressive Environmental Stability Indicator is useful for determining when relative humidity readings on the MR277 have stabilized (for example, when taking ambient readings in an air duct). The circle next to the RH% display line fills and turns green when the relative humidity reading stabilizes.
Connect the MR277 to a Windows™ or Apple™ computer’s USB port using the supplied USB cable. The USB jack is located on the bottom of the MR277, under the protective flap. Once connected, the MR277 can be used as you would any external storage drive.
