| Bump no longer needed! Many thanks to Fluke Europe Netherlands BV, they sent me this section of manual.
Fluke: good job, MANY thanks! 
Notes: -Initial failure of the device was a leaky zener supplying -5V to pair of 4053. LCR meter went back to normal. -Stability: I had some OPA627 available. Replacing all LF356 by OPA627 greatly improved stability of the device. BTW, it is a bit overkill for an LCR meter ... Double AOPs are not replaced yet, but will be in the future. Topic closed  |

| Bump ...
From drawings (many thanks Fluke Europe BV! ), it seems thet there is no calibration to be done, but there is a program service by shorting 'D' point close to the processor. More details on page 3.14 of calibration manual. For those having it ...
Any ideas? Thanks. |

| Hi everyone,
Did domeone already calibrated this device and if so, what is the procedure to do this calibration? This question since this device contains no calibration potentiometer, only 2 potentiometers for +15V/-15V setting. Microprocessor, a 8039 has obviously no EEPROM too. At that time, Philips used fixed resistors on case by case basis, to be changed to recal devices ... Furthermore, if someone has drawings or better, maintenance manual, it could be very helpful. Thanks! |
