3. Calibration
Calibrating the Integrating Sound Level Meter (SL-200) requires an acoustical calibrator which provides a
stable sound pressure at 1kHz and 94dB.
Using the buttons, you can select one of the two types of calibration:
1. Factory – Select this option if you want to use the meter factory calibration set during manufacture.
2. User – Select this option if you want to use your own calibration.
If you decide to select option „User,” you will be able to choose between a new calibration (NEW – press
button ) and the calibration of the user stored in the device’s memory (CURRENT – press
button ).
Option „NEW” allows you to perform a new calibration as follows:
1. Stand away from loud sound sources that may interfere with the calibrator’s signal.
2. Fit Sound Level Calibrator carefully onto the sound level meter and rest the assembly on the table or
other fl at surface.
3. Switch on the calibrator and wait approximately 5 seconds for all levels to stabilize.
4. Press the button to START calibration.
5. Wait until the display shows the value in the range of 93.8 - 94.0 dB.
If after a fi ve-second wait, the result is not within the range of 93.8 – 94.0dB
press the button again
6. To confi rm and save the calibration, press the button.
5. Maintenance and service
SL100 is designed and constructed to provide many years of reliable operation. However, if a fault occurs
that impairs the meter’s correct function, then remove the batteries to prevent rish of futher damage.

ment Care section below.
