Normal Trigger Mode can be used to set triggers such as time triggers, logic triggers and independent triggers for each of up to four analog channels. A wide variety of trigger types can be used, including rise and fall triggers, bi-slope triggers, level (high/low) triggers, and window IN/OUT triggers. You can also set trigger sensing to sense fluctuations in the root mean square value of AC signals, and trigger filters to prevent trigger malfunctions due to noise.

Overview of Trigger Functions

The wave-window trigger is used for monitoring 50-Hz and 60-Hz power supply waveforms. A wave-window (area consisting of the base waveform plus a certain width) is created based on an ideal power supply waveform (sine wave) or the actual power supply waveform. The trigger is sensed when the measured signal is outside the wave-window. The wave- window trigger is used for real-time monitoring for phenomena which cannot be detected by conventional level parameters, such as instantaneous power failures, sags and impulses in the commercial power supply. Separate wave-windows can be set for each analog channel.

Wave-Window Trigger

• Example of Wave Window Trigger Applications
  The OR100E/OR300E Series can be used in real-time monitoring for power supply quality abnormalities when troubleshooting office automation equipment such as copy machines or workstations.

  

• Examples of Trigger Applications
  • Trigger Filter Function
    When a trigger filter is used, a trigger is sensed if the trigger conditions are satisfied and maintained continuously for a preset length of time. Trigger filters can be used to prevent trigger malfunctions due to noise.

    

  • Time-Out Trigger Function
    When the time-out trigger function is used, a trigger is sensed only if the trigger conditions are initially satisfied but not satisfied again within a preset length of time. Time-out triggers are useful for monitoring for periodic waveform level fluctuations.

    

  • Time Trigger Function
    When the time trigger function is used, a trigger is sensed at a set time or during a set time interval.

A half-VGA display is used for 50% better resolution than in Yokogawa's older models.

In addition to scaling, the OR100E/OR300E Series supports statistical calculation functions for determining maximum, minimum, average, root mean square and surface area values for ranges specified with the cursor.
