ds4014 self-cal
« on: July 27, 2018, 10:29:35 pm »
Hi,
I have a new Ds4014 that I have updated to the latest firmware and made a few other tweaks.
The firmware update procedure states to run a self-cal after the firmware update.

Is this a good idea? The scope is brand new. Is the self-cal going to overwrite the factory calibration or does it do something different?

many thanks

Lee

Self cal routines don't write over factory calibration, which is generally protected behind a password and is in a service menu.  In fact, a run of the self-cal after a warm up period is the first step in the full calibration for the DS4000 series.

Yes.

The "factory calibration" of machines with self-cal is probably just somebody at the factory pressing the "self-cal" button.

Your manual says:


Key words: "At any time" - you should really do it before any important measurement.

Or ... just relax. These things are only about 3% accurate (see manual).

Use it to look at wiggly lines on screen, the numbers are really just ballpark figures.

Off to buy some bits to make the 5-1 cable.
