infiRay Mini Series ML19 Thermal Imaging Monocular User Manual

Overview

The Mini series is a multifunction thermal imager with built-in VOx uncooled infrared focal plane array detector. Mini series has small size, light weight, high performance, various purpose and many other strengths. Moreover, a variety of sensors are equipped and it not only can be used as Monocular hand- held thermal imager or portable infrared thermal image sight but also can be used as wearable device when installed on the helmet. Mini series can be widely used in investigation, security, search and rescue, outdoor sports and other application fields.

Operation Functions

The related function such as switch, peripheral, menu and other functions can be implemented through operating the rotary encoder. And all the operations can exit through pressing the encoder for 3 seconds.

Switching on/off

The product will be switched on and display start up logo after pressing encoder for 3 seconds.

The status indicator icon is displayed in the upper left corner of the image and the battery power icon is displayed in the upper right corner. As shown in figure 5-1 of normal display.

Switching off the encoder by putting the lens straight down and pressing the encoder for 3 seconds.

Electronic Magnification

When there is no menu, rotating the encoder can zoom image. The image will be zoomed in with clockwise rotation and zoomed out with anticlockwise rotation between 1.0 and 4.0;
Slowly rotating the encoder, the magnification is adjusted with a step of 0.1 and rapid rotation is amplified by x1.0, x2.0, x3.0 and x4.0;
The current magnification is displayed on the upper left icon;
The center of image is enlarged when there is no reticle and the center image of reticle is enlarged when the reticle is displayed.

Figure 5-1. Normal display interface

When there is no menu, short press the encoder to call up the context menu, as shown in figure 5-2. The four functions clockwise are image correction, image mode, brightness and laser. Rotating encoder can achieve switch function and short press encode can start up the executive function. If there is no operation within 5 seconds, it will exit the context menu automatically. Or it will exit after pressing the encoder for 3 seconds.

Image correction：Short press the encoder to perform the background correction while the lens is facing down and other orientations to perform shutter correction.
Image mode：W(white hot)、B(black hot)、R(red hot)、C(pseudo color).
Brightness：Screen brightness adjustment. There are 1~5 levels can be adjusted.
Laser：Turn on/off the laser designation.

Figure 5-2. Context menu

When there is no menu, long press the rotary encoder for 3 seconds to call up the advanced menu (when long press the encoder, don’t let lens vertically down, otherwise the Mini series will be shutdown). The advanced menu includes five functions which are Device, Function, Reticle, Calibration and Setting. Each function contains several options and corresponding options item po out when select a certain function, as shown in figure 5-3.

Figure 5-3. Advanced menu

Operation：

After entering the advanced menu, short press the rotary encoder to switch among functions.
After a certain function item is selected, rotating the encoder to switch among the option items and a short press locks the certain option or adjusts the parameters.
After locking an option item, rotating the encoder to adjust the parameters and short press performs the option and unlocks the option item.
If there is no operation within 15 seconds, the advanced menu will exit automatically. Or long press rotary encoder for 3 seconds can also exit the advanced menu. The functional details of the advanced menu are shown in table 5-1 and the relevant operation status is shown in figure 5-4, 5-5, 5-6 and 5-7.

Remote Control

The Mini series is built-in bluetooth module. Through bluetooth, the Mini series can be connected with the special bluetooth remote controller or smartphone APP. The bluetooth connection method is as follows:

Turn on the bluetooth function on the Mini series, and the bluetooth icon will be flashing;
Then turn on the bluetooth of the remote controller (or smartphone) within 1 minute, to complete the automatic connection between remote controller (or APP) and Mini series. The bluetooth icon on Mini series interface will stay on after successful connection. The Mini series will automatically turn off bluetooth if there is no remote equipment is connected within 1 minute, and the bluetooth icon will turn grey.
When the remote controller (or APP) is powered off, or out of the prescribed connection distance, Mini series will automatically turn off the bluetooth within 30 seconds.
