The TES-1350A is a sound level meter with a 1/2-inch electret condenser microphone, a 4-digit LCD with 0.1 dB resolution, A/C frequency weighting, and AC/DC outputs through a 3.5 mm coaxial socket. Its measuring ranges are 35 to 130 dB over 31.5 Hz to 8 kHz.
The manual explains safety information, controls and display indications, battery installation, measurement setup, MAX HOLD operation, and calibration using an acoustic calibrator or the internal 94.0 dB oscillator. It also lists operating precautions and product specifications.

The BT mark appears when the battery voltage drops below the operating voltage, so the battery should be replaced with a new one.
Use the windscreen for measurements in windy locations so wind does not cause misreadings.
Set RANGE to Hi, RESPONSE to F, and FUNCT to CAL 94dB; the display should show 94.0 ±1.5 dB.
The MAX HOLD position measures and holds the maximum sound level; press RESET to start a new maximum measurement.
