Default Re: Service manual for Fluke PM6306 RCL Meter anyone?

Now I just need to buy a serial interface as none of my current PC's have it!

@mzspring: Can please you make the de-compiled code available somewhere so I can have a look at it?

Where <NR1> is the number of calibrations since first delivery.

I doubt that mine has been recalibrated since manufacture, so it would be interesting to see responses from other units.

CAL?

CAL OFF (means calibration data not valid or lost)
CAL ON;YY/MM/DD

YY/MM/DD = Year/Month/DAY
is the date of last calibration

Thanks mz. Yes, I'd quite forgotten that the 6306 programmer's manual covered that response.

So the question is what am I seeing? At first I thought the calibration data might be corrupted, but then checksum should have failed and the response would be 'CAL OFF'...

Does your unit return the documented response?

As I was concerned about the calibration data I ran self-test Program 9 which displayed:

1.0003
1-1
CAL


The rotary control cycled through 6 pages:

1.0000
1-2
CAL

0.9984
1-3
CAL

1.0000
1-4
CAL

1.0000
1-5
CAL

1.0000
1-6
CAL


Which seems like quite plausible calibration data.

Cheers
