The HHM8229 meter is a portable professional
measuring instrument with large LCD to show three
lines of readings, as well as a backlight for easy
reading. The single-hand operation design for the
range switch makes measurement simple and easy.
Overload protection and low battery indication are
provided. This is an ideal multi-function instrument with
scores of practical applications for professional,
workshop, school, hobby and home use.
The meter is devised with light and sound alarm to
prevent misconnection of test leads and provide
additional protection against damages caused by
improper operation. The 5-in-1 digital multi-tester has
been designed to combine the functions of sound level,
luminance, humidity and temperature meters, as well as
a digital multimeter.
The HHM8229 digital multimeter can perform
measurements of AC/DC voltage and current,
resistance, frequency, duty, capacitance, as well as
continuity and diode test. Both the reading and unit of
measurement are displayed on the LCD, and includes
both autorange and manual operation. Auto range and
manual range are both available. The HHM8229 is
equipped with auto power off function, reading hold
function, and relative measurement function.
