  • Page 4: Introduction

    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).
  • Page 5 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 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. Light–Level Measurement Units Both Lux and Ft-cd (Foot Candle) measure luminance. Ft-cd Lux = lumens per square meter. Ft-cd = lumens per square foot .

  • Page 10: Sound Calibration

    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.
  • Page 11 Note… To calibrate the sound meter, you must change the current reading to match the calibration point of the acoustical cali- brator (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.

  • Page 12: Measurement Procedures

    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.
  • Page 13 When measuring intense light, the meter displays x10 to indicate that the value displayed is 1/10 the actual value. 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).
  • Page 14 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). Because the hygrometer readings are taken while holding the meter upside-down, the measurement values display upside-down on the LCD (180°...
  • Page 15 Thermocouple Temperature Measurement This procedure requires an optional Type-K thermocouple probe. 1. Press POWER to turn the meter on. 2. Ensuring correct polarity (+ –), carefully plug a Type-K thermocouple probe into the Temperature Thermocouple Input Port at the bottom of the meter. Temperature differences between the probe and the meter may cause inaccurate results.
  • Page 16 Hold Mode Selection 1. Press POWER to turn the meter on. 2. Using the FUNCTION button, select your desired measurement function (Sound, Light, Air-Velocity, Relative Humidity, or Temperature). 3. When a value displays that you want to retain, press HOLD. The meter freezes the current measurement value and discontinues measurement while in Hold Mode.
  • Page 17 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.
  • Page 18 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. The meter exits Record Mode, displays the current reading value, and resets to automatically turn off after 10 minutes of inactivity.
  • Page 19 Hands-Free Operation The Environmental Quality Meter includes both a built-in mini- easel and a tripod screw-mount for easy hands-free monitoring. Field Tripod (840093) is available as optional accessories and attach simply via the screw-mount located on the back of the meter. To use the easel: 1.
