In most situations, hot water with a mild liquid detergent is an effective cleanser. Acetone easily cleans most organic matter, and hypochlorous solutions will remove algae,bacteria, or molds. To prevent cell damage, abrasives or sharp objects should not be used to clean an electrode. A cotton swab also works well for cleaning. - Page 11 5. When an SD card is used for the first time a folder is created on the card and named the model number. Under the MODEL number folder, the MODEL number and AUTO+YEAR folder will be automatically created. e.g.: /CDH-SD11/AUTO2017/….. 6. When data logging begins, a new folder named M(month)/D(date)/H(hour)/M(minute) is created on the SD card in the AUTO+YEAR folder.
- Page 12 4. Data directory in SD card : /CDH-SD11/ MANUAL.csv Note: When manual data records full (199 points), logging will continue, but with new data overwriting old. If you want to keep the previous data, rename the file “MANUAL.csv” in /CDH-SD11/ MANUAL.csv is required.
