Hey everyone,
I'm new to this list, and have been trawling through the past conversations for some help on the calibration procedure of KM367. it's a clone board, yet to be calibrated.
I can set VR1, but then am stuck on the next step. Is there a trick to this?
The way I am doing it is
1. have controls in the normal position.
2. turn on
3. select "manual" (program leds turn off)
4. flick the "test" switch. at this point, the program leds stay off.
5. flick the "tape enable". at this point, 1-8 leds are still off.
6. flicking back to tape disable, leds 4&5 light up. further switching of the tape switch does not change 4&5. they stay on.
7. adjusting VR6 & VR7 make no change to leds 4&5 lighting up.
Jumping to the next step, adjusting VR2 does not change the amplitude of the triangle wave. it is staying for me at around 4.4v p-p.
If i've got something wrong here, let me know.
help is much appreciated!
Anthony.
