8.1. Manually Saving Readings
When you are happy that the readings are stable, press the
M+
key to snapshot the
readings along with the time, date, GLP (calibration) data and position (GPS models only).
As each reading is saved, a numeric memory location ‘Tag’ will be briefly displayed which
you can note down. This Tag can be used to identify readings at a later date, both on the
Micro 800 Meter and when using Micro 800 Link software.
8.2. Recalling and Viewing Saved Readings
To recall your readings, press the
MR
key. On entering Memory Recall mode, the most
recent Tag and set of readings are displayed first.
M TEMP:012.5
q
C M
DO:098.5%
DO:08.5mg/L
SAL:1.05ppt
During Memory Recall, an ‘M’ is flashed in the top left and right corners of the screen
alternatively with an up/down arrow and a left/right arrow. This is to indicate that the Meter
is in Memory Recall mode and that other screens can be accessed using the arrow keys.
To see earlier readings, press the up arrow key. Just before each set of readings is
displayed, the Tag, along with the date and time the readings were taken will be briefly
displayed. The date and time the readings were taken are also displayed on the bottom line
of the GPS Position Screen during Memory Recall.
To view all the parameters within one set of readings, use the left/right arrow keys as
described earlier. To exit Memory Recall mode, press the
ESC
key. If no key is pressed for
30 seconds, Memory Recall mode will be automatically cancelled.
8.3. Recalling GLP Data
Each time a set of readings is added to memory, the date of the last successful calibration
of each function is also appended. This is called GLP (Good Laboratory Practice) Data. In
addition to the date of the last successful EC calibration, the Calibration Standard value at
which the EC was calibrated is also displayed (see
Calibrating EC in section 12 for further
details).
To view the last successful calibration date for the DO and EC electrodes for any particular
stored reading, enter Memory Recall mode, scroll to the reading you are interested in using
the up/down keys, then press the
MENU
key. The screen below will be displayed.
