When the internal measurement value (R.V.) falls below the specified trigger level, the
sampling begins. When it goes beyond the trigger level, the sampling finishes. When the
sampling finishes, the internal measurement value (R.V.) minimized during the sampling
period is held as a judgment value (P.V.).
The external input is not required.

*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
calculation function is used.

• After the sampling starts, if the internal measurement value (R.V.) becomes
" " before the sampling goes beyond the specified trigger level, the
sampling is automatically finished and the minimized value during the
sampling period is held as a judgment value (P.V.).
