You can manually select a windscreen correction

for Windscreen UA-0237. No correction is made

for unknown microphones

Trigger Input None

MATRON

Handswitch

Voltage Level

This parameter should be set to match the

equipment connected to the Trigger Input socket

on the connector panel of the analyzer

Set it to None, if not used.

Set Trigger Input to MATRON Handswitch if the

analyzer is being used in the MATRON system.

This setting should also be used if you want to use

the Handswitch ZH-0680 for manually triggering

signal recordings

Set Trigger input to Voltage Level if you want to

control signal recording by a voltage level

generated by external equipment. The Voltage

Level should generate at least 2 V for On and less

than 1 V for Off. The duration of the steady level

should be at least 1 s, so it can be recognised by

the analyzer
