Manually Saving ReadingsWhen you are happy that the readings are stable (see section 6.3: Error!Reference source not found.), press the M+ key to snapshot the readingsalong with the time, date, GLP (calibration) data and position.As each reading is saved, a numeric memory location ‘Tag’ will be brieflydisplayed which you can note down. This Tag can be used to identify readingsat a later date, both on the Macro 900 Meter and when using Macro 900 Linksoftware.8.2. Recalling and Viewing Saved ReadingsTo recall your readings, press the MR key. On entering Memory Recall mode,the most recent Tag and set of readings are displayed first along with the dateand time the readings were taken shown on the bottom line of the screen.M TEMP:012.5°C MORP:0415.2mVpH:08.2102/Apr/12 15:04:01During Memory Recall, an ‘M’ is flashed in the top left and right corners of thescreen alternatively with an up/down arrow and a left/right arrow. This is toindicate that the Meter is in Memory Recall mode and that other screens can beaccessed using the arrow keys.To see earlier readings, press the up arrow key. Just before each set ofreadings is displayed, the Tag will be briefly displayed. To view all theparameters within one set of readings, use the left/right arrow keys asdescribed earlier. To exit Memory Recall mode, press the ESC key. If no key ispressed for 30 seconds, Memory Recall mode will be automatically cancelled.8.3. Recalling GLP DataEach time a set of readings is added to memory, the date of the last successfulcalibration of each electrode is also appended. This is called GLP (GoodLaboratory Practice) Data. In addition to the date of the last successful ECcalibration, the Calibration Standard value at which the EC was calibrated isalso displayed (see section 14: Calibrating EC for further details).To view the last successful calibration date for each electrode for any particularstored reading, enter Memory Recall mode, scroll to the reading you areinterested in using the up/down keys, then press the MENU key. The screenbelow will be displayed.GLP DATA>pH/ORPDO/ECAux Electrodes
