This standard specifies level recorders with exponential pen response for recording (1) noise and/or vibration levels. This also applies to level recorders (hereinafter referred to as level recorders with attached devices) that perform exponential response recording using the DC output (effective value output) of attached devices, sound level meters, or vibration level meters. Apply standards. In this standard, the configuration and testing requirements for level recorders with auxiliary equipment, etc. are specified in the annex.Unless otherwise specified, these are collectively referred to as level recorders. Note (1) The recording of noise level and vibration level or any of them mentioned herein refers to the recording of noise level or vibration level using AC output signals of JIS C 1502 or J1S C 1510. It is recorded on recording paper and has an accuracy equal to or higher than that of an ordinary sound level meter or vibration level meter.
