Does anyone have a Dickson FH121 adjustment procedure they would like to share?

Appreciate it if it's available.

The unit is a little reminiscent of the Extech RH520A.  The Extech unit did not have any available adjustments.  Have you opened it to see if there are any adjustment potentiometers?  If so, you could perhaps reverse engineer the adjustments.  If not, I would suspect it may be as with the Extech units.  I'll be interested to find out.

Also, it might be worth a phone call to Dickson to ask them what can be adjusted.

Been quite a few years since we retired the last of ours, but if I remember correctly the adjustment required their software. I used to have an old copy but can't find it now. They might send you a copy if you beg like I did. And if memory serves me correctly, even that only allows you to perform an offset adjustment. If you need more than that I think you need to return it to Dickson.

Thanks guys, I appreciate the effort and information. It appears to be a software adjustment and I hate begging! Off to Dickson it goes.
