Setting the Recorder
Pretrigger (WRITE PRETRIG)
• If WRITE TRIG is set to TRIGGER, the data before the trigger (event) generation can
be saved in part of the set file. Setting is done as a percentage of the file capacity in
10% increments.
• If a pretrigger is used (except 0%), it is necessary to set the writing start trigger
(WR_TRIG) to the action in the event/action function.
Setting A/D Converter Integration Time, Filter, Scan Interval, and Filter of
Retransmission Output
Select a SETUP topic Setup tab Select A/D converter time
Filter ON/OFF Measurement scan interval Set the time constant for the filter(only DA/DC)
A/D Converter Integration Time
Select the A/D converter integration time for each unit. Select it from the following:
• Auto: the frequency of 50/60 Hz is automatically switched corresponding to the power
frequency of this instrument. Note that Auto does not function for the standalone DC
power supply model or for extended types using a DC power supply subunit.
• 50 Hz: the integration time is set to 20 ms (50 Hz).
• 60 Hz: the integration time is set to 16.7 ms (60 Hz).
• 100 ms: the integration time is set to 100 ms (10 Hz)
• The default setting is AUTO. However, if the instrument is a standalone DC power
supply model, the default setting is 20 ms (50 Hz).
Filter
Set the filter to reduce normal mode noise, ON or OFF.
Scan Interval
• The duration of time (one scan) in which the measurement of all channels is carried
out, is called the scan interval.
• This interval can be set to any value from 0.5 second to 60 seconds. The shortest is
40 ch/500 ms for the standalone model, or 300 ch/500 ms for the expandable model
(varies with the shortest measurement period of the input module).
Filter of Retransmission Output
Set the time constant for the filter of the retransmission output. The number entered
corresponds to the time constant as follows:
Number 0 1 2 3 4 5 6 7 8 9
Time constant (ms) 4 12 28 60 125 250 500 950 1750 3000
