- The 5 in 1 digital multi-tester has been designed to
combine the functions of sound leve 1, 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 far checking the acoustics of studios,
auditoriums and hi-fi installations.
- The luminance function is applicable to measuring
field luminance with full cosine correction far angular
incidence of light.
- The humidity and temperature functions are suitable
far measuring ambient humidity and temperature, as
well as temperature of ob jects.
- The digital multimeter can perfarm 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.
