INTRODUCTION
The Sper Scientic Environmental Quality Meter with Sound
850069 is a 5-in-1 instrument that functions as a:
• Sound-Level Meter—measures sound levels simulating
the human ear using the A Weighting and Fast Time
Weighting to meet the International Electrotechnical
Commission (IEC) standards (61672, class 2).
• Light Meter—measures light using an exclusive
photodiode and color-correction-lter, light sensor. Meets
the Commission Internationale de l’Eclairage (CIE)
photopic standards.
• Anemometer—measures wind-speed using a low-friction,
ball bearing wheel design to provide exceptional accuracy.
• Hygrometer—measures relative humidity using a high-
precision humidity sensor with fast response time.
• Thermometer—measures temperature using standard
Type-K (NiCr-NiAl) thermocouple input jack for all Type-K
probes (optionally available).

The rugged, light-weight and portable design of the
Environmental Quality Meter allows you to use it almost
anywhere to monitor elements and maintain a healthy and
safe environment.
Recommended exposure limits for the various elements
have been set through government organizations such
as the US Occupational Safety and Health Administration
(OSHA) and the National Institute for Occupational Safety
and Health (NIOSH).
Current recommendations and guidelines are available
through these organizations, as well as many others. (Refer
to Environment References page 26.)

Sound–Level Measurement Units
dB
The decibel (dB) is a logarithmic unit of
measure that expresses the power or
intensity of an acoustic sound.
Light–Level Measurement Units
Lux
Ft-cd
x10
Both Lux and Ft-cd (Foot Candle)
measure luminance.
Lux = lumens per square meter.
Ft-cd = lumens per square foot .
X10 = Value displayed is 1/10 the value.
Air Velocity Measurement Units
ft/min
m/S
km/h
MPH
knots
Feet per minute
Meters per second
Kilometers per hour
Miles per hour
Nautical miles per hour
Relative Humidity Measurement Units
%
Relative humidity (RH) is a term used to
describe the amount of water vapor that
exists in the air and displays as a
percentage.
Temperature Measurement Units
°C/°F Represents the temperature in either
Celsius or Fahrenheit degrees.

SOUND CALIBRATION
This procedure requires an optional 2-Point Acoustical Cali-
brator (850016):
1. Using the directions that accompany the Acoustical Cali-
brator, ensure that the calibrator is operational and is
equipped with the ½” microphone adapter.
2. Insert meter’s sound probe into the calibrator.
3. Turn the calibrator on and select 94 dB.
4. Turn the meter on and use the FUNCTION button to se-
lect the Sound–Level meter function.
5. Press HOLD and MAX/MIN simultaneously for 3 seconds
and release.
The meter enters Calibration Mode and displays two values.
The upper value is the calibration point. The lower value is
the current reading.
