INTRODUCTION The Sper Scientific Advanced Datalogging Sound Meter (Model 850013) uses a single range of 30 ~ 130 dB. This dynamic range eliminates the need to manually select and change ranges, alleviating the problem of lost data associated with range changes in auto-ranging models. All test parameters are simultaneously displayed on a large, bright backlit display that features 0.1 dB resolution and a bar graph. Data can be stored in the meter or directly saved on a computer through the PC interface.
FEATURES ANSI S1.
MATERIALS SUPPLIED Meter USB cable Software Windscreen Calibration tool Recorder output plug 4 AA batteries Instruction manual Hard carrying case 6
POWER SUPPLY The meter is powered by 4 AA 1.5V batteries or an AC adapter. When using the AC adapter, insert the adapter plug into the DC9V connector on the bottom of the meter. Note… When the AC adapter is connected, the meter will supply power from the adapter rather than the batteries. When using batteries as the power source, periodically check the folowing indicator to determine the battery capacity. When the battery power is almost empty, the symbol will disappear from the LCD. Press MEM or REC.

KEYPAD 1. POWER Press to turn the unit on. To turn the unit off, press and hold POWER until “P-OFF” appears on the LCD. Auto Power Off - To save battery life, the unit defaults to the auto power off mode when turned on. The unit will turn off after 30 minutes of inactivity. The auto power off function is disabled when connected to a PC or when the recording function is in process.
KEYPAD To disable auto power off: With the meter turned off, press and hold MEM, and then press POWER to turn the unit on. Continue holding MEM until the meter starts to function. The symbol will disappear from the LCD when the auto power off function is disabled. Note… When the meter is turned on, the LCD shows how much internal memory space is available for use. 2. RECALL Recalls data from the manual store. 3. REC Press to start recording. “REC” appears on the display. Press again to stop recording.
KEYPAD 9. BACKLIGHT Press to turn the backlight on. Press again to turn the backlight off. The backlight will turn off automatically after 30 seconds. 10. A/C Sets frequency rating to A or C scale. 11. FAST/SLOW Sets time weighting to Fast or Slow. 12. Microphone ½ inch Electret Condenser microphone 13. CAL potentiometer Calibration control for level calibration adjustment. 14. PC connection The PC jack signal output is a 9600 bps N 8 1 serial interface.
KEYPAD 15. AC/DC signal output jack Connect the AC/DC output (located on the bottom of the unit) to the level recorder. AC: 1 Vrms corresponding to 130 dB (with frequency weighting) DC: Output: 10 mV/dB DC Signal AC Signal Ground 16. External DC 9V power supply jack Connect the AC adapter. 17. Tripod mounting thread For long-term measurements, the unit can be mounted on a camera tripod. Be careful to avoid dropping the unit. 18.
SETUP MODE Setting the Clock This meter includes a clock that records the date and time along with measured data. 1. Press and hold CLOCK for longer than 2 seconds. 2. Press or to adjust the number, press CLOCK to adjust the next item. 3. The setting adjustment order is year→ month→ day→ hour→ minute→ second. Press CLOCK to complete adjustment. To cancel a setup process, press POWER. Note… An internal (rechargeable) backup battery runs the clock when the meter is turned off.
CALIBRATION The meter has been factory calibrated. Annual calibration is recommended for best results. Calibrate the instrument before use if the meter was not used for one month or longer or was operated in an undesirable environment (high temperature and/or humidity, heavy dust). 1. Prepare for calibration by setting up the meter as follows: Frequency scale: A Time weighting: FAST Measurement mode: Disable Min/Max function. Level range: 30 ~ 130 dB 2.
MEASUREMENT PROCEDURES 1. Press POWER to turn the meter on. 2. Select the desired response time and frequency weighting. Note… If the sound source consists of short bursts or sudden changes in sound level, set the response time to FAST. To measure typical sound level, use the SLOW setting. 3. Hold the meter in a comfortable position or attach to a tripod and point the microphone towards the noise source. The sound pressure level reading will appear on the LCD. Maximum and Minimum 1.
MEASUREMENT PROCEDURES 4. To exit this mode and clear all maximum and minimum values, press and hold MIN/MAX until “MAX MIN” disappears from the display. Note… Maximum and minimum values cannot be saved when exiting the Maximum/Minimum Mode or when the meter is turned off. Datalogging The data storage method can be set to auto or manual. Auto Datalogging To set the interval time: 1. Press INTV. “Int” and a seconds display appear on the LCD. 2.
MEASUREMENT PROCEDURES stored in the memory, “FULL” appears on the LCD. Clearing Auto-Stored Data 1. Press and hold POWER to turn the meter off. 2. Press and hold REC. While still holding REC, press and release POWER. “CLr” appears on the LCD. The LCD displays “SURE 5, 4, 3, 2, 1, 0.” (The meter allows 5 seconds to abort the operation by releasing REC.) Continue holding REC until the meter returns to Normal Mode. The memory is now cleared. Manually Storing Data 1.
BATTERY REPLACEMENT 1. Remove the screw at the top of the battery cover and lift the cover off the meter. 2. Insert 4 AA batteries, ensuring correct polarity. 3. Replace the battery cover and tighten the screw to secure. Note… This meter can use AA rechargeable batteries. A separate charger must be provided for rechargeable batteries because the meter is not designed to recharge batteries.
MAINTENANCE The following actions will keep the meter in good working condition and ensure correct measurement technique: Wind blowing across the microphone may cause additional noise and affect the reading. When taking measurements in a windy environment, the windscreen must be used to prevent interference. Do not store or operate the meter in high temperature or high humidity environments. See Specifications (page 30) for recommended operating environment ranges.
TROUBLESHOOTING 1. Meter connected to PC serial port and turned on but still displays “NO CONNECTION”: All serial ports may be occupied by other applications. Close other applications. If the problem is still not resolved, restart the computer and run the software again. 2. Saving the graph to a file that can be used in Excel: When saving the graph to a file, the default file format is “*ghf.” Select the file type as “*csv” (Excel file format) and save. The file is ready to open in Excel. 3.
