Calibration Procedure
To calibrate the REED R8050, an external calibrator that can provide a
94.0dB signal at 1 kHz is required (REED R8090) in addition to a small
screw-driver.
1. Open the battery compartment and locate
the two calibration potentiometers behind the
9V battery (see diagram)
2. Turn the meter ON
3. Put the meter in the ‘C’ weighting mode
4. Put the meter in the ‘FAST’ response mode
5. Place the REED R8050 microphone into the
calibrator. Set the calibrator to output a 1kHz
sine wave @ 94dB
6. Put the meter in the LOW range
7. Adjust the ‘C (Lo)’ potentiometer for a display
of 94.0 dB
8. Put the meter in the HIGH range
9. Adjust the ‘C (HI)’ potentiometer for a display of 94.0 dB
