I usually do it when the record is on on the turntable but it SHOULD NOT BE SPINNING.
Here are the instructions:
1) Imagine a record having a triangular shape(the spindle hole being the center). Hold the Zerostat approximately 12" away from the record surface and slowly squeeze the trigger at each of the three "corner points" of the record. Take about 2 seconds to squeeze and 2 seconds to release at each of these locations.
2) Pointing the Zerostat at the center of the record slowly squeeze the trigger the fourth time, point the Zerostat awaya from the record(at the floor) and release the trigger.
There's been an issue with a static during LP playback in my system lately, after I upgraded the cartridge from MM Sumiko Pearl to medium output MC Benz Ace...I think I just notice more now since the Ace is so much more revealing.
What I do now(found it mentioned in the forums here) and it's been working real good, is I use the Zerostat as per instructions above, plus I brush the record when it starts to spin with an Audioquest brush, but, and this is funny, you have to moisten the fingers with which you hold the brush's metal body while you are brushing a record, and with the fingers on your other hand also slightly moistened, touch something that is grounded, in my case it's the Pro-Ject Speedbox. I guess the static just gets released better this way.
Works very good and the records are quiet.
Thanks Audphile1 for your reply.
Just curious, are these instructions you listed above from the manufacturer? I bought my Zerostat new and my box did not include any written manual instructions. Does it really require 4 squeezes/releases per record? Somehow I thought it just needs one squeeze/release and that's it. Also, I thought both squeeze and release should be aimed at the record at all times, no?
I just bought a vintage Zerostat kit and the instructions are on it. That's where I got it from.
You need to kind of get a feel for the Zerostat trigger though. Practice a bit on the squeeze/release.
Ok, thanks Audphile1.
I'll give it a try.
Studio, the cap is a test bulb, if you get a light it is supposed to be working but is not for daily use.
Does anyone know if the Zerostat wears out after many years.
I have had had mine for 15-20 years(the older model)
I see...thanks Chadnliz.
Mescabo, according to the Milty Zerostat box, they wrote the gun lasts for about 50,000 trigger operations.
I have yet to wear mine out after 30 years.
From the web:
This amazing little device known as the Zerostat Antistatic Gun is an antistatic "generator" which has numerous applications in any microscopy laboratory. Just squeeze the "trigger" of the Zerostat and a steady stream of ions is released. The "magic" comes from two powerful piezoelectric crystals and a patented compression trigger. Originally developed for removing dust from "vinyl" and before that, normal "phonograph records". In later years the Zerostat antistatic gun was discovered to have great applicability for use in a photographic darkroom to remove dust from film and negatives. After that, a wider range of applications came into being when people running SEM labs found out that it was also ideal for eliminating dust from critical samples or other critical surfaces when the dust attraction was being caused by electrostatic charge. Others have reported that certain insulating specimens, when treated this way, can actually be viewed (admittedly briefly) by SEM without the need to apply further coating.
Each Zerostat unit has a "two cycle" type of operation. When the trigger is squeezed, positive ions are generated and when the trigger is relaxed, negative ions flow. This means that it is possible to induce a charge on a neutral surface using the Zerostat. If the trigger is squeezed, and the Zerostat is removed from the surface before allowing the trigger to return to its original position, a positive charge will be induced. Similarly, pointing the Zerostat at the surface only for the release of the trigger will induce a negative charge
Hold the Zerostat within 12" (30.5 cm) of the surface or object to be treated. Squeeze the trigger slowly for about two seconds, to emit a stream of positive ionized air over the surface of the object. As the trigger is slowly released, a negative show of air ions is produced resulting in static neutralization. Repeat this procedure at several points across the surface of the object.
The Zerostat needs no batteries or electrical supply and unlike other antistatic products, the Zerostat contains no radioactive components whatsoever.
Important notice! Remove the ion indicator from the barrel before using the Zerostat Antistatic Gun to neutralize static charge. Ion indicator is for testing use only.
Caution! Do not use in an explosive or combustible environment.
An old trick is to point the Zerostat away while pulling the lever, then towards the brush when releasing. This gives the record brush a neg. charge and is quite effective for collecting debris. Best results occur by treating the lp while off the platter. Audphile's suggestion for grounding is good, try touching the TT's spindle with one finger and a grounded unit (amp's faceplate?) with another finger to neutralize system static.
...and don't do something foolish like press your finger on the tip of the gun to test if it's working, it hurts like hell.
Release the trigger slowly. Don't just let go. I take up to 5 to 8 seconds to completely released the trigger. You can hear it.
Can it damage cartridges?
Audphile, I haven't read every single post that followed on to your first one, but if you use the (old style) Audioquest brush AFTER you use the Zerostat, you are likely putting static charge back on the LP after you neutralized it with the Zerostat, whether you moisten your fingers or not, because the old Audioquest brush provides no electrical continuity between the bristles and the handle. Zerostat treatment should come last. (There IS a new Audioquest brush that is grounded via the body of the user, by holding its handle during use, thus perhaps it does not create a static charge on the LP. I don't know when the new version of the brush came on the market, but I think it is quite recent.)
I don't argue with the notion that the LP should be sitting still, not rotating, but I do not understand why that would be the case.
I’ve changed my method to the three point plus center.... wow. This thong finally works as I’d always hoped it would. Thanks audphile.
Errr. Thing...not thong. Although they can be fun too.
