Okay, so I admit I'm still using these with my old trusty CSI 2120's.

Anyone have, or recall getting the following error?  It happens regardless if the analyzer is set to RBMware or MasterTrend.

Anyone know why this happens, or have a solution?

For me, this problem pertains only to CSI branded/issued SRAM cards that have the built-in rechargeable battery.  Not all have the problem, I do have some that work fine.

I haven't had this error occur with any other SRAM card, just the CSI rechargeable ones.  You can re-initialize the card, but eventually it'll put out the same error some time later when turning on the analyzer.   It's a shame as I have a small pile of these, half of them being 8mb cards.

I'm not familiar with that card but since you have the issue with built-in rechargeable batteries, perhaps the battery needs replacement.

These cards are a sealed unit, with rechargeable but non-replaceable battery.  There is a "Check Card Battery" function on the 2120, which says "Battery OK" when it's used.  The card battery gets recharged when the analyzer is turned on.  I've taken steps in the past to allow extended charge times, but with no help in the end.  I've wondered though if it really is a battery issue in the end...

Try these steps from NK-1100-0228;

Likely Problem: Analyzer has been updated with firmware version later than the version used to Initialize the card.

Solution:
1) Turn the analyzer off and remove the external card. This will allow turning the analyzer on without getting the error message.
2) Turn the analyzer on and plug in the external card.
3) Initialize the external card

Let me know how you go...

How old are the problem cards? I can tell you from personal experience that things just don’t work as well when they get old. ;-)

Rang -  Thanks for looking into this. 

As for step 2, I normally wouldn't plug in, or unplug the memory card while the meter is turned on, but I'll give it try and report back.     

 

I bet Rusty's right.  Like so many of us, it's probably a memory issue due to old age.

My card is 18+ years old. It says it will soon leave home if I don't use it and charge it more often.

Oli the card I have been using in my DataPac is right at 20 years old and it finally has had enough. New battery did nothing for it. I've broken down and bought a new one.

Nope, tried once more.  Did as outlined.  Turned the analyzer back on an hour later and came up with the same error.

====================================================================

I'm guessing it's still an issue with the rechargeable battery in these cards.  They can't last forever, right?  Since the card's battery gets power from meter for recharging, I'm not sure how the analyzer knows the voltage measured during test is from the battery, or the circuit charging it. 

Thinking I'll throw one in a 2120 on charge for 8 hours, then tear it open and measure the battery's voltage.  Then I should really know, right?

The error appears to been a battery issue.

I opened one card to find a 3volt, ML2016 rechargeable battery.  The voltage measured 2.4volts after a full day of charging.  A day later, it measured just 0.154volts.  After soldering a new battery in place and charging for 1/2 a day, it's been fine.  No more errors.

The cards can actually be opened somewhat easily.  The parting seams are plastic, allowing them to be solvent welded back together.  I might post a "how to" repair under the Tool Tips category once I get some more batteries.

You can get new cards from Portermax.com with replaceable batteries which you can buy from supermarket.  Will be cheaper than a few days time to repair.... But I don't have 2120 anymore.  Gave all my cards away to a trusty in industry person  here in Australia.  Good effort for trying MachDiag!!
