The displayed value of the measured variable will therefore usually differ from the true value of the measured variable. It is recommended that the SV 36 is checked every 2 years with periodic testing of the test equipment to ensure that the level values do not change, and the test results are reliable. - Page 4 SV 36 User Manual Classification of sound level meters and calibrators Acoustic calibrators (see IEC 60942:2017) and sound level meters (see IEC 61672-1:2013 + AMD1:2017) are classified into their respective classes and types for accuracy. Type LS is subject to the most stringent requirements. Devices of this class are classified as the most accurate.

65 kPa to 108 kPa, ensuring accuracy in accordance with IEC 60942: 2017 for Class 1 devices. The SV 36 has a built-in static pressure sensor or this purpose. Note: Due to the feedback control loop, the SV 36 calibrator requires no user adjustment and operates over a wide range of temperature and humidity (see SV 36 data sheet). -
Page 6: Using The Calibrator
This allows the calibrator to switch on automatically when it is placed on the microphone and to switch off when it is removed. Using the SV 36 calibrator is therefore as simple as placing it on the microphone, performing the calibration and removing it from the microphone. -

94 dB to 114 dB or vice versa. When the SV 36 is either ON or OFF, pressing and releasing the button for 10 seconds and releasing it will cause a complete reset of the system. Normally this function is not required. It... -
Page 8: Changing The Batteries
The alternate flashing of the LEDs indicates low battery voltage. It is recommended not to use the SV 36 calibrator in this condition as the generated level may differ from the declared values. Note: Replace the batteries, when the LEDs flash alternately. - Page 9 SV 36 User Manual c) Remove the cover and remove the flat batteries. d) Replace the discharged batteries with new ones, polarised as indicated on the printed circuit board and on the calibrator case. e) Fit the cover so that the LEDs fit into the corresponding holes in the cover.
