For the BSWA 200 gauges, any result above 12.5 kHz can be ignored due to the frequency response of the microphone installed in Class 2 gauges. Hint 2: The data were measured using a 50 mV/Pa microphone for SW 1000 meter and a 40 mV/Pa microphone for BSWA 200 meter. Hint 3: The measurement meets the requirements of GB/T3785 and IEC 61672 standards. -

BCC value is 00H, the sound level meter does not check the data, and the authorised instruction is processed directly. This way you can simplify the transmission of an instruction block, but this method is not recommended for long-distance transmis- sions, as the BCC value is the only possibility to ensure the reliability of data trans- mission. -

5.2.6 Restoration after transmission errors Various errors can occur during a transmission of command block or response block. Below we present the manner in which the sound level meter treats the errors and restores the original status.

Step 4: Press the key located in the upper right corner to choose the firmware, and then press Update to start the program. The whole procedure takes 3 to 4 minutes. ☆ Hint: The device should be reset to the factory set- tings, and after updating the firmware perform at least one calibration, otherwise the sound level meter may work improperly. - Page 47 sponse. The A and C weightings are used more often and defined in IEC and GB/T standards. The B weighting is only defined in ANSI standard. The D weighting re- fers to an international standard that is already invalidated. The D weighting is only available in some old devices.
