2.5.4 Feedback Mode
The FEEDBACK MODE function provides the operator both visual and audible feedback in regard to the
measured leak rate. This function determines how the gas-level graphical display (bar graph located at the
bottom of the display) and audible tone operate as follows.
CONTINUOUS
– The bar graph and audible tone continuously increase and decrease their values in step with
the leak rate. For example, when the leak rate increases, the bar graph moves upscale and the audible tone
increases in frequency. Their maximum values at various leak rates are determined by the Range setting.
