Hello,
I recently purchased a A6302 current probe from eBay and keep getting 588 errors on my AM503B amplifier. I purchased another AM503B amp and A6303 current probe to compare since I couldn¡¯t determine whether it was the amp or probe causing the error. The 588 error follows the A6302 probe.
When I try and degauss, I get the error. I can use the AC amplifier and get a scope waveform similar to my working current probe. But when I put the amplifier in DC mode, the probe doesn¡¯t give a signal at all, apart from a DC offset that cannot be adjusted with the amplifier pot. I¡¯m trying to follow the schematics but am not seeing why this might be right off. Does anyone know why I would able to get an AC signal but not a DC? Is this the hall sensor that might be defective?
Thanks,
Dave
