A ‘new’ 7081 arrived this week and is making itself at home. It seems to be working normally, passes the ‘Self Test’, and I am able to communicate with it via the RS232 interface. I down loaded the CALDUMP and archived the data. The firmware is a ‘DC’ version on this SN 000660 unit (displays ‘VDC BSW 17 Ma 85 13 17’ via the RS232 when ‘Initialise’ is selected) as opposed to a ‘DD’ version on my SN 001523 unit (displays ‘VDD BSW 8 De 86 8 50’). I have archived IC430, IC415, IC414, IC413, IC412, and IC803 from both versions if anyone needs them. I think the ‘DD’ version is already on the web at a couple of locations. Now, a couple of observations and questions. 1. The CALDUMP revealed a Zener Current Token Value of 103. The sticker on the back corner of PCB 5 says ‘HC/20/27. 103’. The Zener Current Token Value appears at the same location on my other 7081. 2. The ‘Cal Key’ that I have, sent to me by another list member, that is used to switch from Norm to CAL to be able to read the CALDUMP and calibrate the meter, fits this new meter. That makes maybe 5 meters that have worked with this same key. If anyone needs a copy of the key for their meter, let me know. 3. When the input is shorted, I see about 0.15 uV. When reading my Fluke 731B, I see about 10.000770 volts while my other 7081 (Cal’d by Ametek in October) shows about 10.000030 volts. I think this means the new guy needs to be calibrated. 4. B1, the battery on PCB 3, a Tadarian TL-2150, ½ AA, 3.4 Volt battery, reads 0.016 volts. That sounds dead to me and probably means I can power down the meter, remove and replace the battery with no loss of data. 5. B401, the rechargeable battery on PCB 14, a Varta 3.6 V, 100 mAH, 3 pin battery (two + pins, one – pin), measures 4.368 VDC with power on and 0.993 VDC with power off. That sounds like it needs to be replaced. However, I am suspicious that if I remove it with power off, calibration constants will be lost. Is that correct? If not, is there a specific set of steps to do to ‘recover’ from the battery replacement? 6. The meter is missing the feet and the ‘bail’. Might anyone have some spares? The meter is quite clean inside, date codes are mid to late 84 and the firmware chips appear to be ‘updated’. I will plan to update it further to the ‘DD’ version. Any other suggestions or advice appreciated. It looks like it will be a good addition to the bench. Thanks, Joe

Fabio, I don't know if it would work with the 7061 or not. I originally thought that it was unique to the meter but this key has worked on every 7081 it has been tried on. I would be happy to send you a copy to see if it works if you can give me the specifics of how to send it to you. I have mailed them to folks in the US taped to a 3x5 card and wrapped in a sheet of paper in a regular envelope with a standard 1st class stamp. If the key works, you can be the 'distributor' of keys for the EU :^).

It would not surprise me that the key work also on the 7061, the keyswitch can be esily tapered with a flat blade :) I didn't notice that you are in US. Is there is anybody willing to send the key to me in italy from europe ? It will cost much less than from usa. There are also some 7061 owners in this list, let me know, if I have no luck I'll contact you Joe and will be happy to pass the key around. Fabio. "J. L.

Just curious. How much to mail an envelope from the US to Italy or vice versa?

Just checked, it is less than I thought for regular mail: from It to US: priority (regular) mail less than 50grams 3,3euro less than 20grams 1,6euro registered mail <50grams 7,3euro <20grams 8euro The delivery times from us to it can be huge, in the 4weeks range or more, italian post can be reasonable for big and costly packages but VERY slow with small regular post, the problem is in the customs offices.

Well, I made some 'scans' of the key and can send that to you. If you can find a 'blank' that will fit your lock, you can 'file' the 'blank' to become the key. If you think that would help. The original key is by MICRO SWITCH USA and it was made in Canada. The 'blank' for that key appears to have been an HV61 and the number on the key is 601. Might also be something you could order from MICRO SWITCH. In the US, the 'blank' that would fit the lock was a Y6 and I had several of them 'cut' to match the original key that I have been sending to folks that requested one. Happy to send you one if you like. Only requirement is that you report back when it arrives and if it works or not.

If you have the scans on the pc you can send to my email, if I have success in finding the blanks and make it work I can pass the key here in eu. Fabio. "J. L.
