The standard SA-3051/SA-3052 measures sound pressure levels up to 136dB. The SPL-175 option
includes a high SPL microphone to allow measurements from 100 to SPL-175. The high SPL mode only
works in the digital SPL display mode. Don’t use the SPL-175 microphone for RTA measurements.
Selecting the SPL operating mode is very simple.
1. Press and hold the
Spl button to enter the digital SPL mode.
2. The display will alternate HI and LO. Release the
Spl
button when the appropriate mode is displayed.
3. When the digital SPL mode is in the HI range, a single LED will stay lit at the left edge of the display.
