How do I establish the encoder direction senses for my Dob?

To check the SETUP ALT STEPS sign, point the Optical Tube Assembly (OTA) to the vertical and DIAL up MODE FIX ALT REF, ALT REF=+90, AUTO ADJUST OFF and then press ENTER.

Now DIAL up MODE ENCODER. The right-hand displayed value should be close to +90 degrees.

Now push the OTA downward in Altitude toward the horizon. The right-hand displayed value should decrease, +89, +88, ... +3, +2, +1, 0 as you go from the zenith toward the horizon. If not, reverse the SETUP ALT STEPS sign and repeat the test.

To check the SETUP AZ STEPS sign, rotate the scope in Azimuth clockwise whilst observing the left-hand displayed value in MODE ENCODER. The Az angle should increase. If it does not, reverse the SETUP AZ STEPS sign.
Thanks Eric!

Hope you have been keeping well.

Couldn't have asked for a better response to Graham's query, so thank you!

Graham, if you need further assistance, please do not hesitate to contact me.

Best Regards
