PULSAR THERMION 2 LRF XP50 PRO Manual

Thermion 2 LRF XL thermal imaging riflescopes are designed for use both at night-time and during the day. They provide exceptional image quality even in adverse weather conditions such as fog, smog and rain without being hindered by obstacles like branches, tall grass, dense foliage, or other debris.

Unlike riflescopes based on electrical-to-optical converters, thermal imaging riflescopes do not require an external light source and are resistant to high levels of illumination.

The riflescopes are equipped with a high precision built-in laser rangefinder which allows distance measurement up to 800 meters.

These riflescopes are designed for hunting, target shooting and recreational shooting, observation and orientation.

• To select a rangefinding reticle, please go to submenu Rangefinder in the main menu.
• To select units of measurement (meters or yards) go to submenu General Settings in the main menu.

Additional Information:

• Accuracy of measurement and maximum range depend on the reflection ratio of the target surface, the angle at which the emitting beam falls on the target surface and environmental conditions. Reflectivity is also affected by surface texture, color, size and shape of the target. A shiny or brightly colored surface is normally more reflective than a dark surface.
• Accuracy of measurement can also be affected by light conditions, fog, haze, rain, snow etc. Ranging performance can degrade in bright conditions or when ranging towards the sun.
• Measuring range to a small sized target is more difficult than to a large sized target.

USB Disconnection

• When disconnecting from the computer, the device will continue to operate from the battery pack (if it is present and holding enough charge).
• If the riflescope is in Memory Card mode and is disconnected from USB, the device will remain on.

Maintenance should be carried out at least twice a year and should include the following steps:

• Wipe the exterior surfaces of metal and plastic parts with a cotton cloth. Do not use chemically active substances, solvents, etc. as these will damage the paint.
• Clean the electric contacts of the battery pack and battery slots on the riflescope using a non-greasy organic solvent.
• Recharge the battery if necessary (50%-80% is recommended for normal use).
• Check the lenses of the eyepiece, objective and rangefinder. If necessary, remove dust and sand from the optics (it is preferable to use a non-contact method). Cleaning of the exterior surfaces of the optics should be done with cleaners designed especially for this purpose.

It is recommended to inspect your riflescope before each use. Check the following:

• The device should be free of any cracks or deformations.
• The lenses should be free of cracks, grease, dirt or debris.
• The battery level of the device should be full. Electrical sockets should be free of salts, oxidation, or other debris.
• All controls should be responsive.

Possible cause

The object is behind glass, which obstructs thermal vision.

Solution

Remove the glass.

Possible cause

These problems may occur during observation in adverse weather conditions (snow, rain, fog etc.).

Solution

The presence of dots is caused by peculiarities of microbolometer or display production technology and is not a defect.

Possible cause

In warm climates, objects in the background of a thermal image heat up differently because of thermal conductivity, generating a high temperature contrast and a sharper thermal image.

In cold climates, objects in the background of a thermal image will cool down to roughly the same temperature, which leads to a greatly reduced temperature contrast and a degraded image quality. This is normal for all thermal imaging devices.

Possible cause

There is an object in front of the receiver or emitter lens preventing signal transmission.

Solution

Make sure that: the lenses are not blocked by your hand or fingers; the lenses are clean.

Possible cause

The device is not being held steadily when measuring.

Solution

Keep the device steady when measuring.

Possible cause

Distance to the object exceeds 800 m.
