Questions about this item

How do I install the LANDTEK ND9B calibrator onto my sound level meter, and what step do people often miss?

Fit the calibrator's output port over the meter's microphone capsule, ensuring a complete air seal; the step most users miss is waiting several seconds for the internal tone to stabilise before reading the display.

What maintenance or replacement will the ND9B need after extended use?

The solid-state circuitry has no user-serviceable parts; only the 9 V battery requires periodic replacement when the output level drifts beyond tolerance.

What limit appears first when the ND9B runs continuously during a long calibration session?

Battery voltage drop is the first limit; as the 9 V cell discharges, the calibrator's output stability can fall outside the specified tolerance before any thermal issue arises.
