Communication Function
Communication interface is possible by GP-IB, RS-232-C, RS-422-A or RS-485.
Report Function (feature of the suffix code /M3; available with models with style number
5 or higher)
Report Channels
60 channels, from R01 to R60 (DR231/DR232)
30 channels, from R01 to R30 (DR130)
Types of Reports
Hourly report: Hourly (every hour) statistical information
Daily report: Statistical information for a day (starting at a specified time)
Monthly report: Statistical information for a month (starting at a specified date and time)
These types of report making can be turned on or off separately.
Output of the Results of Computing for Reports
The DR recorder prints the results on a recording chart or send them to a report output.
Output Formats of the Results of Computing for Reports
Hourly report: Standard format
Daily report: Standard format or enhanced format
Standard format: results of computing daily reports
Enhanced format: results of computing daily reports plus results of computing hourly reports*
Monthly report: Standard format or enhanced format
Standard format: results of computing monthly reports
Enhanced format: results of computing monthly reports plus results of computing daily reports*
The enhanced format applies to either daily reports or monthly reports only.
*: Either the average, instantaneous value or sum in each computing of a report.
Types of Computing for Reports
AVE: Average, maximum and minimum over a preset interval
INST: Instantaneous value at the time of report making
SUM: Sum and cumulative sum over a preset interval
Sum Cumulative Sum
Hourly report Hourly sum Sum over 24 hours (resets at the time to make up a daily report)
Daily report Daily sum Sum over a month (resets at the time to make up a monthly report)
Monthly report Monthly sum Not applicable
Unit Conversion (SUM only)
When inputs over a unit of time are integrated, the unit conversion compensates for any
discrepancy in the unit of value arising between computed values depending on the measurement
interval applied.
INTVL: no conversion;
Σ (results of computing)
/sec: converted to the sum of input in seconds; Σ (results of computing) × measurement interval
/min: converted to the sum of input in minutes;
Σ (results of computing) × measurement interval/60
/hour: converted to the sum of input in hours;
Σ (results of computing) × measurement interval/3600
/day: converted to the sum of input in days;
Σ (results of computing) × measurement interval/
86400
Time to Make Report
Reference dates: 1st to 28th days of a month
Reference times: 00:00 to 23:00
Output Ranges of the Results of Computing for Reports
AVE: -9999999 to 99999999 (with the position of the decimal point dependent on the
measurement and computing channels assigned as report channels)
INST: -9999999 to 99999999 (with the position of the decimal point dependent on the
measurement and computing channels assigned as report channels)
SUM: seven digits for the mantissa and two digits for the exponent
Processing of Faulty Data
AVE: Faulty data are excluded from computing. Data of positive and negative overflows,
however, are included in the computing of the maximum and minimum.
INST: Faulty data are included in computing.
SUM: Faulty data are excluded from computing.
