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.
