Hi Bill,
From: "BIll Ezell" <[email protected]>
That's a little high, a bit worse that what I remember mine being.
So I will try to replace IC201 (ICL7650) as stated in the Service Manual.
But, if it so I fear that the calibration will be lost.
Question, what was your warmup time? These really take about 24 hours to
At least 48 hours.
But, don't try to recalibrate the actual reference voltage unless you have
a very good standard, of which a single Weston cell is not one of.
It's a Transvolt 9154C actually (4 cells with t° stabilized at 0.01°C) but,
I
don't wish to calibrate it because it's still under calibration.
Thanks.
Bye,
Jean-Louis
