Frequently Asked Questions
- Why is barometric compensation important?
Atmospheric pressure directly affects the sound pressure level produced by a calibrator. The Nor1256's automatic compensation ensures accurate calibration output regardless of altitude, weather conditions, or temperature, which is especially important in the variable climates across the GCC. - Does it display the compensated level?
Yes, the OLED display shows the actual compensated output level after barometric correction, along with real-time temperature, humidity, and pressure readings. - What advantage does multi-frequency calibration provide?
By verifying your instrument at both 250 Hz and 1000 Hz, you can confirm proper frequency response across the measurement bandwidth, detecting potential issues that a single-frequency calibrator would miss.
