5.2.4 Operations in Low-Resistance Measurement Pulse Source Mode
5-25
a. When the trigger mode is AUTO:
• The measurement and the pulse cycle repeat at intervals of the specified period time and the
pulse switching time.
• If the measurement does not finish in the specified period, the pulse width does not change but
the pulse cycle is extended and the TpALM indicator goes ON.
• If the source value is changed during pulse generation, the pulse source operation (including
COMPLETE OUT signal output) stops and restarts with the new source value.
b. When the trigger mode is HOLD:
• The measurement starts when the measurement delay time has passed after trigger input.
• Trigger input during measurement is ignored.
• If a trigger is input during range change processing, pulse generation starts when the range
change processing is completed.
c. When setting to Operate
• Pulse generation starts when the Operate processing time has passed after setting to Operate.
d. In Standby or Suspended status:
• The measurement is not executed in Standby or Suspend status.
