INTRODUCTION The Sper Scientific 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 colorcorrection-filter, light sensor. Meets the Commission Internationale de l’Eclairage (CIE) photopic standards.
INTRODUCTION 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).

LCD DISPLAY Sound–Level Measurement Units The decibel (dB) is a logarithmic unit of measure that expresses the power or intensity of an acoustic sound. dB 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.

SOUND CALIBRATION This procedure requires an optional 2Point Acoustical Calibrator (850016): 1. Using the directions that accompany the Acoustical Calibrator, 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 select the Sound –Level meter function. 5. Press HOLD and MAX/MIN simultaneously for 3 seconds and release.
SOUND CALIBRATION The meter enters Calibration Mode and displays two values. The upper value is the calibration point. The lower value is the current reading. Note… To calibrate the sound meter, you must change the current reading to match the calibration point of the acoustical calibrator (e.g., 94 dB). Press POWER at any time to cancel the calibration procedure. 6. Press °C/°F to increase the calibration point value or press Function to decrease the value to match the desired calibration setting. 7.
SOUND CALIBRATION 8. Press UNIT to save the calibration data, exit Calibration Mode, and resume measurement. 9. To calibrate the Sound-Level meter to a second set-point (114 dB), set the Acoustical Calibrator to 114 dB and repeat steps 4 through 7. Note… The 114 dB calibration point displays as a double-digit decimal instead of the full value (i.e., 13.8 instead of 113.8).
MEASUREMENT PROCEDURES Sound-Level Measurement 1. Ensure that the sound sensor at the top of the meter is free from obstruction. 2. Hold the meter with the sound sensor pointing toward the noise source and press POWER to turn the meter on. 3. Press FUNCTION continuously until the meter displays the dB sound-level measuring unit. 4. The meter measures the sound level of the surrounding noise and displays the value in decibels. Light-Level Measurement 1. Press POWER to turn the meter on. 2.
MEASUREMENT PROCEDURES 3. Press LUX/FT-CD to select between Lux and Ft-cd. 4. To ensure measurement accuracy, calibrate the light meter using the ZeroOffset adjustment feature. 5. Cover the light sensor to block any light from registering on the meter. Press ZERO to calibrate the meter to zero. The meter displays the light-level value as 0 and is ready to measure light, even in low-lit and dark areas. 6.
MEASUREMENT PROCEDURES Air-Velocity Measurement 1. Press POWER to turn the meter on. 2. Continuously press FUNCTION until the meter displays the wind-speed and ambient temperature measuring units (ft/min, m/S, km/h, MPH, knots, °C, °F). Because the anemometer readings are taken while holding the meter upsidedown, the values display upside-down on the LCD (180° from the other function displays). 3. Holding the meter upside-down, continuously press UNIT to select the desired wind-speed measuring unit. 4.
MEASUREMENT PROCEDURES 5. Ensure that the air flow sensor is free from obstruction and face the air-flow sensor in the direction of the wind. 6. The meter measures the wind-speed and ambient temperature of the surrounding environment and displays the value. Relative Humidity Measurement 1. Press POWER to turn the meter on. 2. Continuously press FUNCTION until the meter displays the relative humidity and ambient temperature measuring units (%RH, °C, °F).
MEASUREMENT PROCEDURES 3. Holding the meter upside-down, press °C/°F to select between a Celsius (°C) and Fahrenheit (°F) temperature reading. 4. Ensure that the humidity sensor is free from obstruction. 5. The meter measures the relative humidity and ambient temperature of the surrounding environment and displays the value. Note… When moving the meter to a new environment, it may take a few minutes for the humidity readings to stabilize.
MEASUREMENT PROCEDURES 3. Continuously press FUNCTION until the meter displays the temperature measuring unit (°C, °F). 4. Press °C/°F to select between a Celsius (°C) and Fahrenheit (°F) temperature reading. 5. Make contact between the thermocouple sensor probe and the object or area you want to measure. 6. The meter measures the temperature of the object or area and displays the value. Hold Mode Selection 1. Press POWER to turn the meter on. 2.
MEASUREMENT PROCEDURES The meter freezes the current measurement value and discontinues measurement while in Hold Mode. 4. Press HOLD again to exit Hold Mode and resume measurement. Record Mode & Auto-Off Selection To save battery life, the Environmental Quality Meter turns off automatically after 10 minutes of inactivity. To override this feature: 1. With the meter turned on, press MAX/ MIN. The meter displays REC, disables the Auto-Off feature, and enters Record Mode.
MEASUREMENT PROCEDURES 2. While the meter displays REC, you can view both the maximum and minimum measured values by pressing the MAX/ MIN button. The MAX/MIN button toggles between the maximum and minimum measured values. 3. To clear the MAX/MIN values and continue recording, press HOLD. The meter clears the previously recorded MAX/MIN values and enters Record Mode. 4. To exit the Record Mode, press and hold MAX/MIN for 2 seconds.
MEASUREMENT PROCEDURES connect your meter to a PC to store, analyze, and print data. RS232 Cable (840057), RS232-to-USB adapter cable (840094), and Data Acquisition Software (850080) are available as optional accessories. The software interface protocol is 9600 bps, 8 data bits, with no parity and 1 stop bit.
MEASUREMENT PROCEDURES Hands-Free Operation The Environmental Quality Meter includes both a built-in mini-easel and a tripod screw-mount for easy hands-free monitoring. Bench-Top (840092) and Field (840093) Tripods are available as optional accessories and attach simply via the screw-mount located on the back of the meter. To use the easel: 1. Lift up the easel’s bottom edge and extend out using the easel’s hinge. 2.
BATTERY REPLACEMENT 1. If the meter displays the low battery icon , press POWER to turn the meter off. 2. Use a small Philips screwdriver to unscrew the two screws that secure the battery compartment and remove the cover. 3. Remove the old batteries and replace with 6 new AAA batteries, ensuring correct polarity. 4. Replace the compartment cover and re -secure using the two Philips-head screws.
TROUBLESHOOTING No Display: Ensure that you have pressed POWER for longer than 100mS. Ensure that the batteries are in good condition, have proper contact, and are in correct polarity. When in doubt, replace the batteries. (Refer to Battery Replacement page 24.) Display Disappeared: If the low battery indicator appeared on the LCD before the display disappeared, replace the batteries. (Refer to Battery Replacement page 24). Disable the Auto-Off function and place the unit in Record Mode.
ERROR CODES - - - - Measurement is out-of range. Indicates low battery, replace batteries.
