Operating Instructions
Power ON/OFF
1. Turn the meter on by pressing the POWER button. To turn the meter off, press and hold the POWER button for 2 seconds.
Note: This meter can be powered by either six (6) 1.5VDC "AA" batteries or an optional AC adapter (sold separately).
Basic Operation
1. At start up, the meter's default settings are "Auto Range", "A Frequency Weighting" and "Fast Time Weighting".
A
dB
FAST
AUTO
2. Press the Fast/Slow button to select the desired Response Time. If the sound source consists of short bursts, set the response to FAST (125ms). To measure average sound level, select SLOW (1 second).
3. Press the A/C button to select the Frequency weighting. Select "A" Weighting for a general noise sound level, or "C" Weighting for measuring high level noise. "C" Weighting is a standard weighting of the audible frequencies commonly used for the measurement of Peak Sound Pressure Level. If the "C" Weighted level is much higher than the "A" Weighted level, then there will be a large amount of low-frequency noise.
4. Press the RANGE button to scroll through the four dB range types. There are three manual dB ranges to select from and auto range. The manual ranges are described as follows:
Range 1: 30 to 80dB range Range 2: 50 to 100dB range Range 3: 80 to 130dB range

Calibration Procedure
In order to calibrate the R8070SD, an external calibrator that can provide a 94.0dB signal is required (REED R8090). If the meter has been exposed to extreme conditions or has not been used in a long period of time the meter should be calibrated by following steps 1 through 7 below.
1. Remove the windshield ball.
2. Power on the meter.
3. Select "50 - 100dB" range.
4. Select "FAST" time weighting.
5. Select "A" weighting.
6. Insert Microphone into the sound calibrator's microphone adapter.
7. Power on the sound calibrator (R8090).
If the measured value is not within "94 ±0.2" dB, adjust the meter's calibration potentiometer until the display matches the output of the calibrator (94.0dB).

Frequently Asked Questions (FAQ's)
I cannot turn off my meter, do you know why?
Often times the meter cannot be turned off because it is in recording mode ("REC" mode). Make sure to exit that function by holding down the REC button before attempting to turn your meter off.
How long can I record for?
Battery life will depend on a number of factors:
• Quality of Battery
• Whether the beeper is ON or OFF
• Whether the backlight is ON or OFF
• Environmental Conditions during data logging
As a reference, using alkaline batteries with both the backlight and beeper on while automatic data logging at a 2 second sampling rate; the batteries lasted approximately 14 hours.
Does this sound level meter have the capabilities to do an 8-hour TWA?
The R8070SD does not automatically calculate an 8-hour TWA. The user would have to export the data to Excel and calculate the TWA with an Excel function.
Product Care
To keep your instrument in good working order we recommend the following:
• Store your product in a clean, dry place.
• Change the battery as needed.
• If your instrument isn't being used for a period of one month or longer
