Advanced auto switching digital multimeter with frequency measurement mode.

Besides precise measurements of AC and DC voltage, current and resistance this electronic device can measure frequency in Hz. This mode could be used to calculate rotational speed of the motors available on this site. For motors on a Hall Effect IC and motors with optical control it is actually possible to connect this multimeter directly; for all other motors an attachment is needed.
