In Reply to: RE: Atma-sphere MA-1 Bias and DC offset adjustment (older model) posted by kngo44@gmail.com on October 1, 2016 at 10:26:35:
-As a result the Bias is automatic. You only adjust the DC Offset.
Depress the Test button on the rear panel, adjust the DC Offset control for a zero ('0') reading on the meter. Do not do this when signal is applied as the meter can be easily damaged.
Check it again after 1 hour of operation.
That's it- pretty easy.
