General Overview

Thank you for purchasing the data logging pH 110
meter from Spectrum Technologies, Inc. This
user’s guide deals with the features that are
unique to the data logging pH 100 meter. Infor­mation on general meter operation is contained in
the accompanying Instruction manual.

The integrated data logger allows the user to eas­ily collect field data with the pH 110 meter. The
logger can be used with or without GPS/DGPS.
After a set of data has been collected, it is
transferred to a PC using the included software.
The data is in ASCII text file format and can be
exported into mapping software or popular
spreadsheet software for analysis.

NOTE: THIS BOOKLET CONTAINS INSTRUC­TIONS ON OPERATING THE DATALOGGER
AND MAINTAINING THE pH PROBE. INFOR­MATION REGARDING THE METER’S GENERAL
OPERATION, CALIBRATION PROCEDURE,
AND DESCRIPTIONS OF ERROR MESSAGES
ARE DETAILED IN THE ACCOMPANYING MAN­UAL.

Data Logger Operation

The data logger has two modes of operation: Com­munication and Measurement. These modes are

indicated by the green LED in the lower left corner of
the meter. When this light is flashing, the meter is in
Communication mode. When the light glows stead­ily, the meter is in Measurement mode.

Communication Mode
When the meter is turned on, it will be in Communi-

cation mode for approximately 10 seconds. While in
this mode, the green LED will flash. It is only in this
mode that a user can initiate a logger communication
(download or reconfiguration). If communication be­tween the logger and software is attempted during
this 10-second period, the logger will remain in Com-
munication mode indefinitely. The meter must be
turned off and then on to change to Measurement
mode (see following section).

Measurement Mode
Approximately 10 seconds after turning on the meter,

the LED light will glow steadily. This indicates the
logger is in Measurement mode. In this mode, you
can calibrate the meter and record data. When you
are finished collecting data, the meter must be put
into Communication mode by turning it off and back
on (see previous section). If you are collecting data
from several sites and need to turn off the meter be­tween data collection sessions, wait until the meter
transitions from Communication to Measurement
mode after turning the meter back on.

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 me­ter’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 geo­referenced 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.
