Frequency Weighting Network:
Characteristics of A & C:
A weighting: The characteristic is simulated as "Human Ear Listing" response. Typical when the environmental sound level measurement is being made, always select to A weighting
C weighting: The characteristic is near the "FLAT" response. It is typically suitable for the checking of machinery noise (Q.C. check) & measuring the tested equipment sound pressure level
Time weighting (Fast & Slow):
"Fast" range simulates the human ear response time weighting
"Slow" range makes it easy to get the average values of vibration sound level
Data hold: To freeze the measurement value
Peak hold: To keep the peak (max.) measurement value
Auto range: 30 to 130 dB

Calibrated via external SOUND CALIBRATOR (SC-941, optional)
Datalogger / Sampling Time / Setting range:
1 second to 3600 seconds
Sampling time can set to 1 second but memory data may loss

Sound level meter measuring procedure
- Power on by pressing the "Power On/Off Button", the meter's default function is "Auto range", "A frequency weighting" and "Fast time weighting". The LCD display will show unit "A. Fast Auto".
- Select "A" or "C" frequency weighting by pressing the "A/C Button"
Note: The characteristic of A weighting is simulated as the "Human Ear Listening" response. Typically always select the A weighting when makes environmental sound level measurement. The C weighting characteristic is near the "FLAT" response. Typically it is suitable for checking the noise of machinery (Q.C. check) and knowing the real sound level of the tested equipment.
- Determine proper measuring range by pressing the "Range Button". After power on the default range is "Auto range". In the same time the lower right display will show the text of "Auto". Under the auto range, press the "Range Button" once step by step will enter to the manual range (range 1, range 2, range 3) and auto range in sequence. There are still 3 manual ranges for your choice:
*Manual range 1 , 30 - 80 dB range: Display will show the unit of "30 - 80".
*Manual range 2 , 50 - 100 dB range: Display will show the unit of "50 - 100".
*Manual range 3 , 80 - 130 dB range: Display will show the unit of "80 - 130".
- According to various measuring sound source, select the Time Weighting (Fast or Slow) by pressing the "Time Weighting Button".
If select the function of "Fast" time weighting, the display will show the unit of "FAST".
If select the function of "Slow" time weighting, the display will show the unit of "SLOW".
Data Record (Max., Min. reading)
- The data record function records the maximum and minimum readings. Press the "REC Button" once to start the Data Record function and there will be a "REC" symbol on the display.
- With the "REC" symbol on the display:
a) Press the "REC Button" once, the "REC MAX" symbol along with the maximum value will appear on the display. If intend to delete the maximum value, just press the "Hold Button" once, the display will show the "REC" symbol only and execute the memory function continuously.
b) Press the "REC Button" again, the "REC MIN" symbol along with the minimum value will appear on the display. If intend to delete the minimum value, just press "Hold Button" once, the display will show the "REC" symbol only and execute the memory function continuously.
c) To exit the memory record function, just press the "REC" button > 2 seconds at least. The display will revert to the current reading.
Preparation before execute datalogger function
- Insert the SD card:
Prepare a "SD memory card" (1 GB to 16 GB, optional), insert the SD card into "SD card socket". The front panel of the SD card should face against the down case.
- SD card Format:
If SD card just the first time use into the meter, it is recommended to make the "SD card Format "at first.
- Time setting:
If the meter is used at first time, you should adjust the clock time exactly.
Data hold of ATE-9030 sound level meter
During the measurement, press the "Hold Button" once will hold the measured value and the LCD will display a "HOLD" symbol. Press the "Hold Button" once again will release the data hold function.
