1.6 Computation Function (/M1 Option)

Communication Input Data (Pen model: C01 to C08, dot model: C01 to C12)

This data type is set using the communication interface (/C7 or /C3 option). Range of values (maximum significant digits is 5):

–9.9999E+29 to –1.0000E–30, 0, 1.0000E–30 to 9.9999E+29

For the procedure of setting the communication input data, see the RD100B/RD1800B Communication Interface User’s Guide M-4233.

Status of the Remote Control Input Terminal (D01 to D05, /R1 option)

The status of the remote control input signal (1 or 0) can be used in the computation. Use D01 to D05 (the number following the letter D is the remote control input terminal number) to specify the status in the equations.

Handing of the Unit in Computations

In computations, measured/computed values are handled as values without units. For example, if the measured value of channel 01 is 20 mV and the measured value of channel 02 is 20 V, the computed result of 01 + 02 is 40.

Recording Computation Channels

Trend Recording

Trend recording is possible by setting the recording span for each computation channel. The recording span of computation channels can be set in the range of –9999999 to 99999999 excluding the decimal.

Zone recording and partial expanded recording are also possible.

Assignment of Computation Channels to the Pens (Pen Model)

Trend recording is possible by assigning computation channels to arbitrary pens. Only display or printout is possible for measurement channels or computation channels that are not assigned to a pen. Assignment of pens is possible only on models with the computation function.
