AUX1 parameter field and is saved with the measurement
data file, similar to the other measured parameters. This
input can be used, for example, for registering the wind speed
together with the measurement result.
Selecting Frequency Weighting
The Freq. Wgt. parameter field only appears when
AC Output is selected for the Aux 1 socket:
● Linear
● Det. 1
L frequency weighting is used when Linear is selected. When
you select Det. 1, the frequency weighting selected on the
RMS detector is used.
Setting Up Aux 2
In the Aux 2 field you can select:
● DC Output
● DC Input
● Trigger Input
● Trigger Output
DC Output supplies a DC output signal equivalent to the AC
output signal. It is the time weighted signal (Fast, Inst.) from
detector 1. Full-scale indication corresponds to 4.0 V DC
(50 mV/dB).
The function of DC Input is similar to that of Aux 1. It is
used to set up the Aux 2 input to a DC Input. The external
DC input must be in the range 0 to 4 V and the resolution
is 5 mV. The DC input signal is displayed in the AUX2 pa-
rameter field and is stored in a similar way to the other
measured parameters.
External Trigger starts a measurement when an external
trigger voltage is applied. The trigger level is 2 V (refer to
Specifications). A trigger is ignored if Mediator is not paused
and displays the Measurement Window.
