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 34B 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 34B User Manual Each of the following types (LS, 1 and 2) allows a wider tolerance range (see Table 1). Table 1. Tolerances for these types of acoustic devices, except for the maximum extended measurement uncertainty (f = 1kHz)

SV 34B User Manual Note: Calibration should only be performed when the '114 dB' LED is lit continuously. The LED called “LOW BAT.” presents the batteries status. When the combined battery voltage is less than 2.1 V the “LOW BAT.” diode will blink with a frequency of approximately 2 Hz. It is recommended to not use the calibrator in this state as the generated level may differ from the declared values. - Page 8 SV 34B User Manual 5. Carefully place the cover so that the diodes fit into the corresponding holes in the cover. 6. Hold the cover with one hand and carefully tighten the fixing screws. 7. Fit the rubber cover.
