Calibration
The procedure for calibrating the meter is given in
the accompanying meter instruction manual.
Taking and Data Logging Measurements
When the probe is inserted in soil or water, the me-
ter's LCD will immediately begin indicating the pH.
When this value stabilizes, the meter locks on to that
value and the LCD will display READY in the upper
right corner. To capture this value with
the data logger, press the HOLD/
ENTER button followed by the Print
button. The Print button is on the
lower right corner of the keypad next to
Print button
the Range button.
If the readings are not being geo-referenced, the
green LED will briefly flash off and then back on. If
the readings are being geo-referenced (see GPS
Connection, p. 10) and a GPS signal is found, the
green LED will turn off for a slightly longer time, then
glow steadily. If the readings are being geo-
referenced but no GPS signal is found, the LED will
flash 3 times, then glow steadily. In this case, the
EC reading will be recorded without latitude/logitude
values. Check the GPS battery status as well as the
connection to the data logger.
