Series II Level Meter Internal DIP Settings
PPM 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:
Integration (Rise) Time is
5 ms
(-2 dB),
Return (Fall) Time is
1.7 seconds
(20 dB)
Integration (Rise) Time is
10 ms
(-2 dB),
Return (Fall) Time is
2.8 seconds
(24 dB)
Integration (Rise) Time is
5 ms
(-2 dB),
Return (Fall) Time is
1.5 seconds
(20 dB)
Integration (Rise) Time is a single sample,
Return (Fall) Time is
1.5 seconds
(20 dB)

Single Sample:
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
20
for a diagram of the
919174
PCB and the DIP switch locations.
Switch positions
1
and
10
are NOT used and should be left at the factory set position.
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.
