DS-2000 Frequently Asked Questions

Use the DC output of the sound level meter. Assuming the DC output voltage is 2.5V at full scale and 0.5V corresponds to a level of 10dB, set the DS-0221 to DC for input coupling, set the unit name in unit calibration to "dB", and in the menu [Analysis] → [Calculation Function], if the sound level meter range is 100dB, enter the formula "TIME*20+50" in DISP1. If the sound level meter range is 90dB, the formula in DISP1 is "TIME*20+40", and if the range is 80dB, the formula is "TIME*20+30". This will display the level on screen 1.
