jolida 502b manual bias adjustment

i use shorter probes and a short screwdriver and have never had a problem. i have big hands as well. i think you may be overly concerned with forcing probes into a real tight and locked position. the probe slots are not top of line but then again you do not need to sink the probes in very far to get a solid read out. i use a digital radio shack unit and it is 1,2,3.

did not mean to imply your method was inferior, etc... i was speaking to OP. just wanted to point out that the connections to spikes do not have to be rock solid to get job done. if i had longer tools it probably would be easier as a matter of fact but the probes can stay in place free standing long enuff to let go of them for adjusting slot screws. ntl, i think auto bias is a gret option, i wish that feature was offered on mine but it was introduced later on.
