INTRODUCTION The Sper Scientific Hybrid-Powered Environmental Quality Meter 850068 is a 4 -in-1 instrument that functions as a: Light Meter—measures light using an exclusive photodiode and colorcorrection-filter, 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.
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. The Hybrid-Powered Environment Quality meter also offers a Green power source through a built in hand-crank generator, enabling battery-free operation.

POWER TYPE SELECTION Hybrid Power (Green) Selection 1. Slide the Power Type Switch up to the G position to use the meter’s Green power source instead of battery power. The low battery indicator will display in the upper left corner of the LCD display. 2. Lift and extend the generator’s handcrank located at the bottom of the unit. 3. Rotate the handle clockwise to windup or crank the generator to create power for the meter. Cranking the meter’s generator for 20 seconds will offer several minutes of energy.
POWER TYPE SELECTION Battery Power Selection 1. Ensure that you have correctly installed the 9V battery in the battery compartment. (Refer to Battery Replacement page 22). 2. Slide the Power Type Switch down to the B position to use the meter’s battery power source instead of Green power. Note… The battery life is greater than 1000 hours when using alkaline batteries (250 hours when using general purpose batteries). MEASUREMENT PROCEDURES Light-Level Measurement 1. Press POWER to turn the meter on. 2.
MEASUREMENT PROCEDURES 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. Uncover the light sensor and ensure that the light sensor on the front of the meter is pointing toward the lumination subject and is free from obstruction. 7. The meter measures the light level of the surrounding environment and displays the reading.
MEASUREMENT PROCEDURES Air-Velocity Measurement 1. Ensuring correct pin alignment, insert the Anemometer plug into the PROBE IN Anemometer socket located at the top of the unit. 2. Press POWER to turn the meter on. 3. 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). 3. Continuously press UNIT to select the desired wind-speed measuring unit. 4.
MEASUREMENT PROCEDURES 6. Face the air-flow sensor (marked with a yellow dot) in the direction of the wind. 7. The meter measures the wind-speed and ambient temperature of the surrounding environment and displays the value.
MEASUREMENT PROCEDURES 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). 3. 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.
MEASUREMENT PROCEDURES Thermocouple Temperature Measurement This procedure requires an optional TypeK thermocouple probe. 1. Press POWER to turn the meter on. 2. Ensuring correct polarity (+ –), carefully plug any Type-K thermocouple probe into the Temperature Thermocouple Input Port at the top of the meter. Temperature differences between the probe and the meter may cause inaccurate results. Allow a few minutes for the probe and meter to adjust to ambient temperature. 3.
MEASUREMENT PROCEDURES Hold Mode Selection 1. Press POWER to turn the meter on. 2. Using the FUNCTION button, select your desired measurement function (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. 4. Press HOLD again to exit Hold Mode and resume measurement.
MEASUREMENT PROCEDURES 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, enters Record Mode and begins recording maximum and minimum values. 2. While the meter displays REC and when you are ready to view the maximum and/or minimum measured values, press the MAX/MIN button.
MEASUREMENT PROCEDURES 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.
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 one DC 9V battery, 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. Display Disappears: If the low battery indicator appeared on the LCD before the display disappeared, replace the batteries. Disable the Auto-Off function and place the unit in Record Mode. (Refer to Record Mode and Auto-Off Selection page 19).
