2. DESCRIPTION
- This meter is a portable professional measuring
instrument with large LCD to show three lines of
readings, as well as back light for easily reading. The
‘single-hand operation’ design for the range switch
makes measurement simple and easy. Overload
protection and low battery indication are provided. It
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 sound level function is applicable to measuring
noise level in factories, schools, offices, airports and at
home, and for checking the acoustics of studios,
auditoriums and hi-fi installations.
- The luminance function is applicable to measuring field
luminance with full cosine correction for angular
incidence of light.
- The humidity and temperature functions are suitable for
- 6 -
DIGITAL MULTIMETER
measuring ambient humidity and temperature, as well
as temperature of objects.
- The 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.
- Both auto range and manual range are available
- This meter is equipped with auto power off function.
- This meter is equipped with reading hold function.
- This meter is equipped with relative measurement
function.
