Hi all,
Yesterday I receive my Keithley 2000, I buy it for 170€ shipped, the seller said no errors, so when it arrive I've plug the DMM and no errors on screen, good.
Cosmetic aspect:
- The bottom of the unit has some scratchs.
- It has no bench kit (so the bottom scratchs)
- The front face plate is all yellow
- The red Keithley has some scratchs
- The with 2000 Multimeter has some scratchs
- The display lens has some minor not deep scratchs
- The Local word is almost gone
- The rear cover of the Scan card is missing
Inside aspect:
- Very clean unit
- Very clean PCB
- No signal of soldering that I can see
- No rust
One thing I noted is there is no ATMEL chip inside, so this is what I've inside.
U165 - Orbit 6715A
The Electrolytic Capacitors are:
C104 - H9555 85º
C131 - H9644 105º
C146 - H9633 105º
C149 - H9644 105º
C156 - H9633 85º (The big 6800uF 16V)
The Main Board shows 2000-102-02F, guess this is the revision of the board.
Firmware Rev. A06 A02
Calibration date - 03/20/03
Calibration Date Due - 03/20/04
Count - 4
Pictures will come in shortly, no battery on the camera.
The repair log will be this
1 - Changing the 5 Electrolytic Capacitors for new ones (maybe Panasonic, Chemi-Con KMG series)
? Any suggestion here.
2 - Cleaning the front plate with hydrogen peroxide (10 Volumes)
3 - Remove the scratchs from the display lens
4 - Buy some SST39SF020A-70 FLASH ROMs to burn the new A19 firmware (the ones I can find end with 70-4I-NHE or 70-4C-NHE) what is good for this?
After this maybe start looking for a Cal lab here in Portugal to send the meter to Calibration and upgrade to A20 firmware.
