Question about US Night Vision Ultra PVS-7B Goggles

1 Answer

Powering down Unit powers off after a short use. Sometimes operates up to two minutes but usually less. Also seems to shut down faaster with the Ir "ON". Initially I thought that it must be the batteries. I replaced with new AA energizers. No luck. Again I replaced with Duracell. No Luck. I tested the voltage of each battery and found no less than 1.5 volts per battery. I tried Ni-Cad batteries with an initial output of 1.63 volts each. Again no luck. I am utilizing my PVS 7B in complete darkness as to avoid the bright light shut down possibility. I'm fresh out of ideas. Any suggestions? Thanks -Jay

Re: Powering down

How long have you had the system? Did you purchase from USNV or private party? If from USNV why not call them up and send it in for repair. If from private party,,,,,that's the chance you take. Sounds like you have either a failing power supply or an electrical short somewhere. In any event the system should be looked at by somebody who knows about night vision. If purchased within the past 2 years it will still be under warranty.

I think I answer you question--when?? Take the good CCTV camera and hook it up to monitor. Then hook up the CCTV camera and turn it on. Point the working CCTV camera at the bad camera that is turn on. Now, look at the monitor which is working with your operational camera. Look at the bad camera while it on, and see how many IR LED's you can see on the bad CCTV, while it turn on. You should be able to the IR LED glowing red. If not, then there is a problem with bad CCTV IR LED's. Short wire, no power to the IR LED's. stewbison

Hello, Thank you for your help. My product turns on but I am unable to view anything out of it. The IR also turns on but I have the same problem, I can not see anything out of it. Thanks again,...

Hello, This is a typical problem with these Russian manufactured NV monocular. Without disassembling the unit and doing some basic trouble shooting on the circuits. NV monocular I have work on. The problem seems to be 1st generation image tube goes south in one fast stroke.

If you can find someone to work on this NV monocular. Only thing need is know that the cathode of the image intensifier tube operates at 15KV switch dc which are 90 degrees out of phase. In other words, it just AC voltage. The tube will have operating current at 12ma to 10ma.

Also, I can't use this forum for drumming up bussiness. I am retired and my experience go back to 1965 work on PVS2 and others. stewbison

Hello, on your Night Owl Optic NV100, it same as the Kalinka Zenith NV. First, you IR switch is a montary switch. As long as your finger push the button it stay on. Release the button it goes off.

The montary green glow after shuting off you monocular NV devise is do to capacitors discharging and keep the image intensifier tube on for a few seconds. The switch on/off is a Russian computer plastic switch it could stick sometimes. See if the rubber cover over the switch can be removed with taken it apart. If the rubber cover can be removed. Then a good switch cleaner to the clean the switches (both at the same time) See if this works. stewbison

Hello. It seems that you have a few problems here. I am just taking a guest at what wrong with Meade NV. Broken wires, bad on/off switch, faulty electronic components, none operational image intensifier tube. Now, these monoculars are manufactured in Russian and the quailty is fair. There are a few companies in Russian that manufacture NV image tube that are very good. Not with Meade, NO, NV, Zeith, and a few others. Sorry, stewbison

Whenever I press the power button, the led indicator lights up but when I release the button, it turns off also. I replaced the battery with a new one and the same problem is encountered. What do you think...

when you said it turns completely off? i have a simular device and it only illuminates faintly, but i have a IR button that lites it up. otherwise unit is in a stand by, IR does the illuminateing of view. its like compareing a quartar-moon to a full-moon. but you could have a switch that is broke. the switch is on a timer to shut off to save battery

NVN3: No difference with power on or off

Most night vision when switched off will stay 'on' for a period of time. After a short time you should not see anything just black. You can't look through a night vision monocular that has been off for a while. The image you see is actually an image on a screen inside unlike a regular monocular or binoculars. Turning it on powers the screen. When turned off the screen is still warmed up and takes time to turn off. Like some old TV's. If you haven't used it for some time and pull it out for night viewing and can see a picture when you haven't pushed the on button. The unit is malfunctioning as it is staying on.

2 buttons on my night owl optics nigt vision power and IR Led how do i use it ?

Power = power
IR works only if the unit is on. It will give you light in total darkness for up to some 50-80 yds. With any ambient light at all the IR is useless.
