Peak-to-peak hold
The difference between the maximum value and minimum value of the specified period
(sampling period) is held as a judgment value (P.V.).
„ When "Level" is set for "6. Timing input" (page 4-27)
The sampling period is from the falling edge of the timing input to the next rising edge. On
the rising edge, the difference between the maximum value and minimum value of the
internal measurement value (R.V.) during the sampling period is held as a judgment value
(P.V.). When the timing input is turned OFF, the next sampling period begins.

*2 The main unit (IG-1000/IG-1500) displays the calculation value (CALC value) when the
calculation function is used.

„ When "Edge" is set for "6. Timing input" (page 4-27)
The sampling period is from the rising edge of the timing input to the next rising edge of the timing
input. On the rising edge, the difference between the maximum value and minimum value of the
internal measurement value (R.V.) during the sampling period is held as a judgment value (P.V.).
When the timing input is turned ON, the next sampling period has already begun.
