4-3 Calculation Function

The internal measurement value (R.V.) for the "main unit" and the "expansion unit

additionally installed next to the main unit (referred to as expansion unit 1)" can be

calculated (addition or subtraction).

If there is more than one expansion unit, the calculation function can be used between the

"main unit" and the "expansion unit 1" only.

There are two calculation modes for the calculation function.

• Addition Mode

• Subtraction Mode

The calculation result of the internal measurement value (R.V.) for the "main unit" and the

"expansion unit 1" is referred to as calculation value (CALC value).

The "main unit" operates with the calculation value (CALC value) considered as a judgment

value (P.V.).

The "expansion unit 1" operates with its internal measurement value (R.V.) considered as a

judgment value (P.V.).

The calculation function cannot be used when a mixture of units from the following groups

is used: IL-S025/IL-030/IL-S065/IL-065/IL-100, IL-300/IL-600, and IL-2000.

The calculation function can be used when a combination of units from within each of the

following groups is used: IL-S025/IL-030/IL-S065/IL-065/IL-100 and IL-300/IL-600. The

calculation function can also be used when multiple IL-2000s are used in combination.

Point

1. When using the calculation function, the setting of the averaging

of expansion unit and sampling rate will be changed to the same

setting as the main unit.

2. If the sampling rate is set to 0.33 ms or if the interference

prevention function is ON, the timing for updating the main unit

and expansion unit's internal data will not match. In this case,

when measuring a moving target using the calculation function,

the measured value may be greatly differ from the actual value.

Calculation Value (CALC value)

Reference

• The calculation value (CALC value) can be displayed on the sub display

(lower level) on the main unit.

"Sub Display (Lower Level)" (page 3-4)

• When the hold function is used, the calculation value (CALC value) is not

held.
