2000M

[MIRCS]

First is anyone having problems with this unit passing calibration?

Second, has everyone seen the new procedure? This new procedure really bothers me in the fact that you preform the External Cal in the preliminaries. This will alter the data on this item. If it is down to a 6 month cycle....I believe there is a reason. By nominalizing the unit before checking any of the parameters is not going to show how the unit is actually maintaining it's accuracies through it's interval.

Maybe I'm the only one that has a problem with this.

Nahh.. my last two bases, F.E. Warren and RAF Lakenheath, problems with both of them.  The 2000M is a piece of junk, in my opinion, and somebody up there knows it.  Supposedly, there is a replacement for it.. time will tell.

Oh it is a piece of junk. But I'm not having mine fail calibration. I have not adjusted them in 2 years.

This thing is way overspec'd IMHO.  It's been a few years since I've actually cal'd one but I've assisted on quite a few cals.  Seems like they are getting to be redlined to a point where we should have kept the 2790 or the "Biddle" boxes.  The major problem that I've seen with the cal is right around zero VDC.  The K-pro has added a check (10mV,  Ithink) that the manufacture doesn't verify in their comm data.  I've sent two back for warranty repair (one of them several times).  It got to the point that I was requesting a replacement item instead of a repair action.  After several emails, and maybe a couple phone calls, one of the engineers finally said that he noticed a problem.  I PCSed before I saw the outcome of that issue.

The units can't provide enough current in the Thermocouple Source mode to power several of the units that we calibrate.  You'll notice the problem with non-linear or just plain-ole bad readings.  If you don't have one of the old standards available, get out a DC Source and an ice bath and do it the old fashioned way

When I first  came to Dyess, the 2000s were very difficult to get to pass cal.   After I went through them a couple of times though, they stabilized and have become an "easy" cal; even with ACC watching.
  It is all in the copper leads.

I have found them to be POS. On test cells I use them for the readout accuracy (measure mode) and use a biddle as the source power tee'd to the 2000M, that way I know the actual reading and not the loaded down inaccurate output of 2000M. They simply cannot take a load, and I am sure thats why they fail cal so often is they get overloaded too much and components fail/change value.

I never really had a problem far as the relaiblity of the 2000M. They were always fairly simply to use. Far as cal and repair, I did have a few hiccups with repairing on once. The damn thing wouldn't hold a charge. Once I fixed that, it wouldn't cycle through selftest. POS.

[MIRCS]

It was equipment envy.     The AF needed a unit to replace the Biddle POS so they looked no further than the Navy...........and the rest was history.................

And that's why the Navy had the Ectron 1100
