Page 2 BE SURE TO READ BEFORE USE Introduction Thank you very much for purchasing our paperless printer DS252. This product, as is connected to our loadcell indicators or digital indicators through the SI/F (two-wire serial interface), records indicated values etc. on a CF card. External equipment data other than our indicators can also be recorded with optional BCD input or RS-232C interface.
Page 3 Safety Precautions Be sure to read for safety. In order to have an DS252 Paperless Printer used safely, notes I would like you to surely follow the documents indicated separately on WARNING CAUTION Notes indicated here are the serious contents related safety. Please use after understanding the contents well.
Page 4 WARNING Warning on design ● For the entire system to function safely when the DS252 becomes faulty or malfunctions, provide a safety circuit outside the DS252. Warning on installation ● Do not modify the DS252. Doing so may cause fire or electric shocks.
Page 5 CAUTION Caution on installation ● Do not install in the following environments. - Places exposed to direct sunlight - Where the temperature/humidity exceeds the range of the specifications. - Places containing large quantities of salt or iron powder. - Where the main body is directly affected by vibrations or shocks. ●...
Page 6 Features of the DS252 ■ Recording of weighing data as electronic data Since weighing data is recorded on a CF card in CSV format, the data can be retrieved by commercially available spreadsheet software, so that it can be easily processed by a PC.
Page 7 Appendix ..Specifications and after-sales service of the DS252 are explained. Explanatory marks in this manual Attention or limitation for proper functioning of the DS252. Be sure to read this Note to prevent incorrect operation. Useful or referential information using the DS252. Recommendable in to read.

6 Record data 6-2-3. Recording of ST (sub total) / GT (grand total) The sum of data having been recorded by ST/GT operation and statistical data are recorded by code (*). (*) Sorting depends on "26 : Code Sorting Type"(page47), "23 : Number of Code Digits"(page45) and "22 : Code Selection"(page45).
Page 107 When GT (grand total) operation is performed, it is attempt to write the data on a CF card. Perform GT operation with a CF card inserted in the DS252. By performing GT operation, the previous data is cleared.
Page 108: Cf Card
6 Record data 6-3.CF card The data having been recorded in the internal memory is written on a CF card. There are two ways of writing: WRITE operation and GT operation By WRITE operation, the data in the internal memory is written as it is. By GT operation, the data in the internal memory and statistical data are written on a CF card and the previous data is cleared.

6 Record data 6-3-3. File name A file recorded on a CF card is named as WRITE operation day (D)/hour (h)/minute (m)/second (s).extension (CSV). Example) If WRITE operation is performed at 14:30:45 on the second day, Recorded file is named: 02143045.CSV When a file is created, if the same file name already exists on the CF card, the extension will be changed as "001,"...

8 years. The time may become out of sync as the backup battery is exhausted. Trouble 2 Values of sub totals/grand totals are abnormal. The decimal point recorded by the DS252 depends on the decimal point on the Cause 1 indicator side. If the decimal point on the indicator side is changed during recording, sub totals/grand totals will not be calculated correctly.
