3.2 Setting Measurement Presets
The E1L allows you to set multiple temperature spots for fast and accurate measurements:
- Center Spot: Displays the temperature at the center of the screen.
- Auto-Hot Spot: Automatically identifies and displays the hottest temperature in the view.
- Auto-Cold Spot: Automatically identifies and displays the coldest temperature in the view.
To access these settings, press the power button to display the menu bar. Navigate to the 'Rule' page and select your desired spot measurements. Press the power button again to switch on/off, or the return button to exit.

The HIKMICRO E1L can pinpoint temperature anomalies with Center, Hot, and Cold spot tracking.
3.3 Enabling Laser Pointer
The built-in laser pointer helps to accurately determine the location of problems by indicating the center point on the actual object.
- Press the power button to show the menu bar.
- Select and enable the laser pointer option.
- In the live view interface, hold the trigger to turn on the laser pointer. Release the trigger to turn it off.

The laser pointer assists in precisely locating the center point of the thermal measurement on the target object.
3.4 Changing Color Palettes
The E1L offers multiple color palettes to visualize thermal data, allowing you to choose the ideal scale for your specific job:
- White Hot
- Black Hot
- Rainbow
- Ironbow
To change the palette:
- Press the power button to show the menu bar.
- Select the 'Palettes' function.
- Navigate through the 4 color palettes.
- Press the return button to exit.

Choose from various color palettes like Rainbow, Ironbow, Black Hot, and White Hot to best visualize temperature differences.
