Triggering
Explanation
This function activates a trigger when the trigger source signal crosses a specified level.
Trigger Source
Select the trigger source from CH1 to CH16.
Note
If you set the trigger source to a value other than CH1 to CH16, see the sections below.
• Time: Section 6.8, “Setting the Timer Trigger (SIMPLE)”
• LogicA or Logic B: Section 6.9, “Setting the Logic Trigger (SIMPLE)”
• Ext (TRIG IN terminal of the side panel): Section 6.6, “Setting the External Trigger (SIMPLE)”
• Line (commercial power supply signal): Section 6.7, “Generating Triggers on the Power
Signal (SIMPLE)”
Trigger Level
When Measuring Voltage
Selectable range: Within voltage range
Resolution: Varies depending on the input module (see the table below).
When Measuring Temperature
Selectable range: Measurement range of each thermocouple
Resolution: 0.1°C or 0.1 K (set within the measurement range (varies
depending on the thermocouple type)
For a description of the measurement range of thermocouples,
see section 5.14.
When Measuring Strain
Selectable range: ±(Measurable range)
Resolution: 1 µSTR or 0.0005 mV/V
Trigger Level Resolution
The selectable resolution varies depending on the input module.
