Overview
The 3801-50 is a multifunction, high-performance digital
multimeter that can be used for voltage (DC/AC/AC+DC),
current (DC/AC/AC+DC), resistance, continuity, diodes,
electrostatic capacity, frequency, frequency counter, duty
ratio, pulse width, and temperature measurement. In
addition, this instrument is equipped with a pulse output
function that can be used to check a variety of pulse sig-
nal instruments. Furthermore, this instrument can be
controlled by computer and transfer measurement data to
the computer when the optional 3856-01/02 is used.
Measurement Capabilities
* DUTY ratio
The duty ratio is the ratio between the pulse width and
the pulse cycle. This instrument displays this ratio in
terms of 100 (%).
