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, oces, airports,
home, etc., checking acoustics of studios, auditoriums and Hi-Fi installations.
The Light function is used to measure luminance in the eld. 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 specied maximum:
Indicates operators must refer to the explanation in this manual.
Indicates terminals at which dangerous voltage maybe present.

OPERATING INSTRUCTION
Measuring Sound Level
1. Set the function switch to the dBC position.

3. The C-weighting curve is nearly uniform over the frequency range from 30 to 10,000Hz, thus
giving an indication of overall Sound level.
4. The Fast response is suitable to measure shout bursts and peak values from sound source.
5. The sound level will be displayed.
6. Note: Strong wind (over 10m/sec.) striking the microphone can cause misreading for
measurement in windy locations, a windscreen should be used in front of microphone.
Measuring Humidity
1. Humidity Measurement for indoor use.
2. Set the function switch to the ON position.
3. Place the meter in the room.
4. Read the %RH in the display for about two hours.
Measuring Light
1. Set the function switch to the desired (“lux” or “x10 lux”) range.
2. Face the photo detector to the light source in a horizontal position.
3. Read the luminance nominal from the LCD display.
4. Over-range: If the instrument display “OL”, the input signal is too strong, and a higher range
should be selected.
5. When the measurement is completed, Remove the photo detector from the light source.
6. Spectral sensitivity characteristic: To the detector, the applied photo diode with lters
makes the spectral sensitivity characteristic almost meet C.I.E. (International Commission on
Illumination) photopia curve V (λ) as the following chart describes.

MAINTENANCE
Battery and Fuse Replacement
If the sign “ ” appears on the LCD display, it indicates that the battery should be replaced.
Remove screws on the back cover and open the case. Replace the exhausted battery with new
batteries. (1 x 9V battery NEDA 1604, 6F22 or equivalent)
The fuse rarely needs replacement and blows almost always as a result of the operator’s error.
Open the case and replace the blown fuse with ratings specied.
Warning: Before attempting to open the case, be sure that test leads have been disconnected
from measurement circuit to avoid electric shock hazard.
Replace fuse only with specied ratings:
Fuse1: F 10A / 600V fast blow.
Fuse2: F 500mA / 660V fast blow.
