This is a handheld precision sound level meter with integral functions that can simultaneously perform noise measurement and real-time frequency analysis in 1/3 and 1/1 octave bands.
**Features** - Built-in real-time frequency analysis function: 1/3 or 1/1 octave frequency analysis is possible with this single unit (main channel). - Dual measurement of main and sub-channels: With two noise measurement circuits, it allows for simultaneous measurement by selecting frequency weighting characteristics or time weighting characteristics, such as measuring with "A-weighting" while recording a "C-weighting" signal. - Equipped with a comprehensive data memory function: Data can be saved in manual or auto mode. One block of memory is reserved for manual storage and two blocks for auto storage. - Infrared remote control port: Remote operation is possible with an infrared remote control that has 18 functions. - Backup function: The settings for level range and frequency weighting characteristics of the noise meter are retained even when the power is turned off, allowing you to set it back to the same settings as the last measurement just by turning the power on. - Energy-efficient design for continuous 8-hour measurement: Achieves double the operating time of conventional models with alkaline battery specifications. - Large LCD display with backlight allows for nighttime measurements.

basic information
■Applicable Standards Measurement Law Precision Sound Level Meter, JIS C 1509-1 (IEC 61672-1) Class 1, JIS C 1513, JIS C 1514 ■Measurement Functions Dual measurement of main and sub-channels for a single input. The main channel performs real-time analysis in 1/1 and 1/3 octave bands. ■Calculation Functions 1) Instantaneous value Lp, equivalent noise level Leq, single event noise exposure level LE 2) Maximum noise level Lmax, minimum noise level Lmin 3) Peak sound pressure level Lpeak* 4) Power average level Ltm3, Ltm5* for maximum values within intervals (3 seconds or 5 seconds) 5) Time-weighted noise levels LX (L1, L5, L10, L50, L90, L95, L99) *1) to 4) are measured simultaneously. However, the * indicates that it is valid only for the sub-channel. 5) measures values from 1 to 99 simultaneously in LX measurement mode. ■Measurement Time - Automatic: 1 to 99 (units: seconds, minutes, hours) - Manual: Measurement continues until the stop switch is pressed ■Measurement Level Range - A-weighting: 28 to 130 dB - C-weighting: 33 to 130 dB - FLAT weighting: 38 to 130 dB
