Procedures:
- Insert the microphone under test into the calibrator’í’»s microphone cavity, ensure that it is fully inserted (Sound level meters with 1/2’í± microphones can be calibrated with this device).
- Slide the range switch to the 94dB position, or the 114dB position as desired. The calibrator generates its signal as soon as the switch is set.
- Read the sound level meter’í’»s value. The sound level meter should read 94dB or 114dB depending on the calibrator’í’»s signal level. If the sound level calibrator does not match the calibrator’í’»s signal (within specification), adjust it as explained in the sound level meter’í’»s operating instructions.
- Slide the range switch to the ’í°OFF’í± position and remove the microphone.
Battery replacement
- Please replace the battery when there is no sound pressure output
- Open the battery cover to access the 9V battery
- Remove the old battery and replace with new 9V battery
