Auto peak hold
When the internal measurement value (R.V.) goes beyond the specified trigger level, the
sampling begins. When it falls below the trigger level, the sampling finishes. When the
sampling finishes, the internal measurement value (R.V.) maximized during the sampling
period is held as a judgment value (P.V.).
The external input is not required.
*1 "11. External input" (page 4-33)
*2 After the power is turned on or reset is input, the judgment value (P.V.) is [] until
the judgment value (P.V.) is first held.
*3 While the
timing input is ON, the sampling does not start. If the sampling is already in
process, it continues.
*4 The main unit (IG-1000/IG-1500) displays the calculation value (CALC value) when the

Reference
• The operation by the timing input is the same regardless of the "6. Timing
input" (page 4-27) setting.
• After the sampling starts, if the internal measurement value (R.V.) becomes
"" before the sampling falls below the specified trigger level, the
sampling is automatically finished and the maximized value during the
sampling period is held as a judgment value (P.V.).
