Peak hold

The maximum value of the specified period (sampling period) is held as a judgment value (P.V.).

„

When "Level" is set for "7. Timing Input" (page 4-23)

The sampling period is from the falling edge of the timing input to the next rising edge. On
the rising edge, the internal measurement value (R.V.) maximized during the sampling
period is held as a judgment value. When the timing input is turned OFF, the next sampling
period begins.

"11. External Input" (page 4-30)

*2 The main unit (IL-1000/IL-1500) displays the calculation value (CALC value) when the

calculation function is used.

“4-3 Calculation Function” (page 4-42)

*3 If the R.V. value (or CALC value) causes an alarm even once during the sampling period, the

hold results will be "-----".

„

When "Edge" is set for "7. Timing Input" (page 4-23)

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 internal measurement value (R.V.) maximized during
the sampling period is held as a judgment value. When the timing input is turned ON, the
next sampling period has already begun.
