Computation Function (/M1)

● Number of Computation Channels

DR231: 30 channels maximum

DR232: 60 channels maximum

● Kinds

Remote RJC, four arithmetic operations, SQR (square root), ABS (absolute

value), LOG (common or natural logarithm), EXP (exponential), statistics

processing (CLOG, TLOG), logic (AND, OR, NOT, XOR), relative computation,

previous data reference

CLOG: Mathematical processing within a group of data that

was measured at the same time (total, maximum,

minimum, average, max. - min.)

TLOG: Mathematical processing of data from a certain

channel over a period of time (24 hours maximum)

(total, maximum, minimum, average max. - min.)

Report Function (/M3)

Instantaneous values of measured data, as well as maximum, minimum, average

and total, for each hour, day or month are printed in tabular form on recording

paper. Analog recording is interrupted while a report is being made.

Report calculation channels

: Up to 60 channels

Note: This function does not allow the results of the report

and computing function to be saved on floppy disks.

(Thus, to be able to transfer the results to a personal

computer, the DP380 report software is needed.

Note that the DP380 software cannot be run

simultaneously with the DAQ32 or DAQ32Plus

software package.)
