8. Memory Mode
8.1. Manually Saving Readings
When you are happy that the readings are stable (see section 6.3:
), 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
Aquameter
®
and when using AquaLink 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 along with the date and time the readings
were taken shown on the bottom line of the screen.
M TEMP:012.5
°
C M
ORP:0415.2mV
pH:08.21

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 will be briefly displayed. 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 electrode 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 section 14:
for further
details).
To view the last successful calibration date for each electrode 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.

Aux Electrodes
Using the up/down keys, select the electrode you are interested in, then press either the
OK key or the right arrow key. If, for instance, you selected pH/REDOX(ORP), the screen
below would be displayed.
