Description

Environmental noise can be monitored.
It can be used as a pass/fail judgment based on sound pressure level measurement.
Compliant standards: Measurement law ordinary sound level meter JIS C 1509-1: 2017 class 2, JIS C 1516: 2014 class 2, IEC 61672-1: 2013/2002 class 2, ANSI/ASA S1.4 2014/Part1 Class 2, CE marking
Measurement function (simultaneously measures the following items with selected time weighting characteristics and frequency weighting characteristics)
Calculation (main channel): Time weighted sound level Lp, time average sound level Leq, sound exposure level LE, maximum time weighted sound level Lmax, minimum time weighted sound level Lmin, time rate sound level LN ( 05, 10, 50, 90, 95) up to 5 pieces
Calculation (sub-ch): Time-weighted sound level Lp
Additional calculation (one of the following can be measured as a simultaneous measurement function with calculation): C-weighted time-average sound level LCeq, C-weighted peak sound level LCpeak, Z-weighted peak sound level LZpeak, I-weighted time-averaged sound level LAIep・Maximum value of IVI time average difference d level LAIMX ・Since the frequency characteristics of the additional calculation are linked with the frequency characteristics of the sub channel, if the sub channel is C characteristic (Z characteristic), the additional calculation LCeq and LCpeak (LZpeak) can be selected
Calculation time: 10 seconds, 1, 5, 10, 15, 30 minutes, 1, 8, 24 hours and any time can be set manually, manual calculation time / up to 24 hours
Microphone: Model/UC-52, Sensitivity level/-33 dB

Z-weighted peak sound level: 60 dB to 141 dB
Self-noise level: A weighting / 19 dB or less, C weighting / 27 dB or less, Z weighting / 32 dB or less
Measurement frequency range: 20 Hz to 8 kHz
Frequency weighting characteristics: A, C and Z characteristics
Time weighting characteristics: F (fast) and S (slow)
Level range switch: None (linearity range 113 dB)
Bargraph display range: up to 110 dB (20-130 dB)
Bar graph display switching: Set the upper and lower limits of the bar graph in 10 dB increments
Effective value detection circuit: Digital calculation method
Sampling period: Lp, Leq, LE, Lmax, Lmin, Lpeak/20.8 μs (sampling frequency 48 kHz), LN: 100 ms
Correction function: Windscreen correction function / Compliant with JIS C 1509-1, JIS C 1516, IEC 61672-1, ANSI/ASA S1.4 even when the windscreen is attached, Diffuse sound field correction function / Compliant with standards (ANSI Corrected frequency characteristics to comply with /ASA S1.4)
Delay time: Set the time from when the start key is pressed until the start of measurement (OFF, 1, 3, 5, 10 seconds)
Last data removal function (back erase function): When measurement is paused with the pause key, data that goes back a set amount of time from that point is excluded from calculations (OFF, 1, 3, 5 seconds)
Display: TFT color transflective liquid crystal display with backlight WQVGA (400 x 240 dots) *LCD display has touch panel (capacitance type) control, numerical display update cycle/1S, bar graph update cycle: 100 ms
Store: Manual / Manually record measurement results for one address at a time, Number of recorded data / Internal memory up to 1000 data sets (SD card: depending on capacity *1), Auto *2 / Automatically instantaneous values at each set time (Lp mode) , Continuous recording of calculated values (Leq mode) at each set time, Lp store cycle / 100 ms (0.1 s), 200 ms (0.2 S), 1 s, Leq 1s, Leq calculation cycle: 10 seconds, 1, 5, 10・15, 30 minutes, 1, 8, 24 hours, measurement time / up to 1000 hours (depending on SD card capacity *1)
Data recall: View store data
Setting memory: Up to 5 sets of settings can be saved in internal memory and recalled. It can be started with the settings of a file stored in advance on the SD card.
Waveform recording *2 *3: File format/uncompressed waveform WAVE file, sampling frequency/select from 48 kHz, 24 kHz, or 12 kHz, data length/select from 24 bit or 16 bit
Output: DC output/DC signal output with frequency weighting characteristics selected by calculation, output voltage/bar graph display 2.5 V/25 mV/dB at full scale, AC output/linked to frequency weighting characteristics selected by calculation A Outputs AC signal with frequency weighting characteristics selected from , C, Z, output voltage/bar graph display 1 Vrms (effective value) at full scale
Comparator output *2: Open collector output (maximum applied voltage 24 V, maximum current 60 mA, power dissipation 300 mW) turns ON when the set level is exceeded.
