I paid $300 for my Elite, it was no $500 VMC but hey not bad
Speaking of Instantrons and repairs, I have a question I hope someone who has used my machine can help me with. I am embarrassed to ask, since I fear this is another case of "user error".
But I want to make sure if it isn't me I send it off to be properly repaired if need be. I read the manual and still can't figure it out, again maybe it is my lack of training or something.
I have the machine set with the computer off (requiring the footswitch and no insertion autodetect and delay) and the auto/manual set to manual (no automatic timing) the meter set to display mA/galvanic and finally modality set to galvanic only.
When in this configuration, I have the ground attached to myself, insert the needle into a follicle and press the footswitch to turn on 0.3mA of current. Instead of displaying 00.3 on the meter, it constantly goes up and down, from positive to negative, displaying all sorts of illogical values (at least illogical to me.) If I touch the needle to the electrode directly, it displays a -1 constantly (null?). The RF indicator light also comes on, even though modality is set to galv only and the RF settings are all set at 0.
When I have the computer on (in auto or manual mode) the meter shows exactly the current I have dialed in (say 0.3mA so the meter displays 0.3). if I have the computer off but in automatic mode, the same thing occurs, it correctly displays the mA I have selected on the dial.
With the computer off and mode set to manual, the sensation of the current at a given mA level is the same as if the computer was on and/or mode was set to automatic. So, in other words, 0.3mA on a given area feels the same regardless of whether the computer is on or off, or if the mode is set to manual or automatic.
A friend, who is an electronics technician, said that in computer off/manual mode the meter is dancing around because the circuit is not consistent and something is causing resistance to vary and that throws the digital meter off. He also said that computer on is adjusting the current constantly to maintain the desired level, as would just having the mode it set to automatic.
My question is, are the weird meter readings expected or does this sound like some sort of user error/inexperience on my part? Thanks
