The CR70 uses DC to power the CRT filament. DC and AC RMS are basically equivalent. So 6.3 VDC on a CRT filament is just fine. No, your DMM has a very high impedance and will not load the supply down like the filament will. You'll need to measure the voltage while it's connected to the CRT.
You meter might have a static charge built up on the plastic face. Try wiping it with an anti-static dryer sheet like "Bounce" |

Here it is. https://www.youtube.com/watch?v=CSMIkESgn98 Am I doing something fundamentally wrong here? Or is my unit just bust? edit: I realized soon after making this video that you meant to wipe the plastic face where the needle is. I can be a bit daft at times :p. Nevertheless, does anyone have any suggestions about the other issues with the unit? Last edited by spacediver; 12-22-2016 at 02:14 PM. |
