INTRODUCTION
The 6 in 1 Digital Multimeter and Environmental Tester has been designed to combine the
functions of Sound Level Meter, Light Meter, Humidity Meter, Temperature Meter, Non-contact AC
Voltage Test Meter and Digital Multimeter.
It is an ideal multi-function Instrument with scores of practical applications for professional and
home use.
The Sound Level function can be used to measure noise in factories, schools, offices, airports,
home, etc., checking acoustics of studios, auditoriums and Hi-Fi installations.
The Light function is used to measure luminance in the field. It is fully cosine corrected for the
angular incidence of light. The light sensitive component used in the Meter is a very stable,
long life silicon diode. The Temperature function uses a semiconductor sensor and K type
thermocouple. The digital Multimeter performs AC/DC Voltage, AC/DC Current, Resistance
measurement and Audible Continuity, and Diode test
SAFETY INFORMATION
This Multimeter has been designed for safe use, but must be operated with caution. The rules
listed below must be carefully followed for safe operation.
NEVER apply voltage or current to the Multimeter that exceeds the specified maximum:
Indicates operators must refer to the explanation in this manual.
Indicates terminals at which dangerous voltage maybe present.

When the measurement is completed, Remove the photo detector from the light source.
Spectral sensitivity characteristic: To the detector, the applied photo diode with filters
