3.6 Audio Threshold/Tone Usage

Depress the ← / → THRESHOLD switches until the desired threshold
is set. Plug a set of 32 Ω headphones in the jack on the top face of
the unit.

If the shielding level is less than the threshold, a variable tone is
emitted. Low frequency tones correspond to low (poor) shielding
levels, while high frequency tones signify high (better) shielding
levels.

If the shielding level exceeds the threshold, no tone sounds.

Depress the lock switch to toggle the control lock function. With
the control lock enabled, the operator is protected against
accidental control inputs invalidating a test.
