Level Meter Internal 10-Position DIP Switch Settings

This 10-position DIP switch is accessed by removing the top cover of the AMP unit and is located on the 919174 PCB (the same
PCB on which the 6-position rear panel DIP switch is located). See page 21 for a diagram of the 919174 PCB and the DIP switch
locations.
Do Not Use
NOTES:
1) Switch positions 1 and 10 are NOT used and should be left at the factory set position.
2)
The Peak Hold - Manual setting allows the bargraph display meters to indefinitely maintain the peak hold value until it is reset by
the operator, either by pressing a reset button (a special option specified at time of order) or by removing power and then
reapplying power to the unit (unplug/replug power cord). Contact Wohler Technologies for more information about this feature.
3)
Contact Wohler Technologies for information about custom scales.
PPPM Characteristics (Ballistics):
The PPM characteristics determine the Integration Time (rise time) and Return Time (fall time) of the level meter. The
Integration Time is the time it takes for the lighted segments of the level meter, after application of a 5 Khz tone at a certain
reference level, to rise within a specified number of dB of that level. Return Time is the time it takes for the lighted segments of
the level meter to fall a certain number of dB after removal of a 5 Khz tone of a certain reference level. The PPM characteristics
available for selection using DIP switch sections 7 and 8 of the 10-position Internal DIP Switch (as shown in the above diagram)
are as follows:
