FAQ | Pulsar

1. What is the advantage of Merger LRF XQ35 compared to the Merger LRF XP50 and Merger LRF XL50?

The Merger LRF XQ35 is the lightest and most compact device (181x133x68) in the Merger line, weighing only 830 g (including batteries).
Its operating time is 11 hrs, when operating time of the Merger LRF XP50 is 9 hrs. and Merger LRF XL50 – 8 hrs.

2. My image is blurry or out of focus.

Please make sure you have made the following adjustments:

First, adjust the dioptre adjustment by rotating the eyepiece dioptre rings to clearly see the icons on the display and in the status bar.
Second, adjust the lens focus to see the object of observation clearly. Please note that re-focusing may be required as the distance to the object changes.
Do the image calibration – either in manual mode (with lens cover closed) or in automatic mode.
Select the most suitable amplification level (“Normal”, “High”, “Ultra”) depending on the specific observation conditions.
Go through the different colour pallets.
Manually adjust display contrast and brightness. We recommend keeping those two values at similar levels. A huge difference between them badly affects the image quality.
Check smoothing filter. If needed turn it on or off.

3. My image freezes from time to time. Is this a defect?

During the calibration process the image freezes on the screen – this is normal and not a defect.

Default calibration mode is “Automatic” (the software decides when calibration is necessary) but you can change it to “Manual” mode in the "Main menu" => "Calibration mode" to calibrate the riflescope when you need to base on actual image quality. Please close the lens cover prior to manual calibration. We recommend using automatic mode all the time. Please read more about calibration in the user manual for your thermal device. https://www.pulsar-nv.com/glo/support/manuals/2966/merger-lrf-calibration-mode/s2475/

4. I can see a ghost image / residual artefact of the previous image. What is wrong?

You are using the manual calibration mode without closing the lens cover. Please make sure the lens cover is closed during calibration or switch to the automatic calibration mode if you do not want to close the cover.

5. I can hear a clicking sound during calibration. Can I turn it off?

No, a clicking sound is normal in the automatic and semiautomatic calibration modes.

You may switch to the manual calibration mode to avoid the sound. Remember to close the lens cover to make sure no ghost images appear on the display.

6. Why do I need to calibrate the image?

Calibration levels the background temperature of the microbolometer and eliminates image flaws (such as vertical stripes, ghost images of previous objects etc.). Intervals between calibrations depend on operating time: the longer a thermal imager operates nonstop, the less frequently calibration is required.

7. There are defective pixels (or pixel clusters) on the screen of my thermal imaging device.

You may try repairing the pixels using the respective menu item of your thermal imager. For details, please refer to the user manual. https://www.pulsar-nv.com/glo/support/manuals/2966/merger-lrf-defective-pixel-repair/s2483/

8. My Merger LRF is not measuring distance correctly.

Please take note of the following:

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, colour, size and the shape of the target. A shiny or brightly coloured surface is normally more reflective than a dark surface.

Measuring range to a small sized target is more difficult than to a large target. Accuracy of the 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.

When measuring range to a small-sized target located more that 400 meters away, it is recommended that you put your elbow against a solid surface. This is due to possible hand tremors and difficulty hitting the target with the beam at a longer distance.

9. Does the rangefinder use a safe laser?

All of our products, including Merger LRF, feature 1 Class Safety (standard IEC60825-1:2014) laser which means it's harmless to the eyes. Nevertheless, please avoid looking directly at the emitting lens of the rangefinder.

10. What is the housing made of?

The housing of Merger LRF is made of high-quality reinforced magnesium alloy.

11. What battery is used in the Merger LRF?

12. The external battery falls out of the Merger LRF binoculars.

Please make sure the battery is installed correctly as recommended:

Install the battery into the battery compartment that a pictogram in the form of a “dot” on the battery on the left. You will hear a click when the battery is placed correctly.

13. Why does the display turn off when I move the device away from my face?

The proximity sensor is working.

The proximity sensor can be turned off in the device settings https://www.pulsar-nv.com/glo/support/manuals/2966/merger-lrf-general-settings/s2478/

When the proximity sensor is off, the display can be turned on/off by pressing the ON/OFF button.

14. The Merger LRF doesn’t turn on.

If Merger LRF will not turn on, press and hold down the ON button for 15 sec, the scope should turn on. If this does not help, probably the battery is empty.
