Our basic bias probe heads work in conjunction with a multimeter to provide inexpensive, accurate, and quick plate current results. These probes are built with a direct break at the plate connection. This provides an accurate plate current measurement (no screen current error).
Our bias probes are terminated with high quality banana plugs (4mm) which work with most all standard Multimeters that have removable test leads.
Our probes measure in direct current, DCA. Most modern digital multimeters have settings for DCA measurements and ranges specifically in a mA scale. Please confirm you have a meter with these capabilities before ordering! If you have any doubts about compatibility please reach out to us.
