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.

Identifying the Correct
Com Port
The computer Communications Port to which the PC-3.5 serial cable is connected can be identified by using a paper clip
1. Disconnect the meter from the serial cable.
2. Click on the Com Port button on the main software screen. This will bring up the Port Selection screen.
3. Select the Com port to be tested and click on the
Port Test button. In the Port Test screen, click the Test Port Now button.

4. If the “Connection OK” message box (see fig. 1) is displayed, another device (such as a modem) is probably connected to that port. This is not the port you will be using with your meter. If the “No Connection” message box (see fig. 2) is displayed, this port may be the one connected to your serial cable and you can proceed to the next step.
Figure 2 Figure 1
5. Place a paperclip on the end of the serial pin so that it touches both the tip of the pin and the metal area between the two black rings (see fig. 3). Again click on the Test Port Now button. If the message “Connection OK” now appears, this is the Com port connected to your serial cable.

Logger Software
Meter Type
The Field Scout software supports all of Spectrum Technologies’ portable data logging meters. Be sure to select the pH 100 Meter from the Select
Meter Type screen Connecting to your Computer
To communicate with the data log­ger, connect the gray interface cable to the pH 100 meter’s RS-232 port. The port is located behind the panel at the base of the meter (marked RS-232). Open the software and turn on the meter so it is in Communication mode (see Data Logger Operation, p. 4). In order to communicate through your com­puter, the COM port connected to your serial port must be selected. For most machines, this will be COM 1. If you are having trouble connecting, try se­lecting another COM port. This can be done by clicking the COM port toolbar button or by clicking “Select Comm Port” from the File menu.
Meter Settings
Clicking on this button will bring up the Meter Settings screen. This screen allows you to configure the data log­ger. The Meter Name will be the title on the first line of the

downloaded files.

If the box below the logger name field is checked, the logger will store GPS data only if it has been dif­ferentially corrected. If the differential correction is not found, only the pH reading will be stored in the data file. A time zone correction should be entered in the last box. Appendix 1 (p. 12) lists time zone corrections for several cities.
Download After clicking the Download button, a progress bar will confirm that data is being extracted from the log­ger. When com­pleted, the Save Data As box will appear. From here you can give the data file a de­scriptive name and select a folder in which to save it. The folder selection field on the right allows you to browse to any folder in your sys­tem.
When the file has been saved, the software will give you the option of immediately viewing the file. The data file is stored as a comma-delimited text file and may be viewed in any text editor or spreadsheet soft­ware.
Clear Memory Data is not automatically removed from the logger memory after a download. The Clear Memory but­ton clears all data from the memory.

GPS Connection
The data logger searches for a GPS signal when the meter is powered up. If a signal is found, latitude and longitude values will be added to the data file. If a GPS signal is not found when powering up, the meter will not search for it when taking readings. If the meter is turned off and back on, it will again search for the GPS signal. Be sure the meter is in
Measurement mode (see p. 4) before taking any readings.
When taking a geo-referenced data measurement, the LED will turn off while collecting the GPS signal. The meter is again ready to take a reading when the LED returns to a steady glow. If the data logger loses the GPS signal, the LED will flash briefly be­fore returning to Measurement mode. In this case, check the GPS battery status as well as the connec­tion to the pH data logger.
GPS Settings Your GPS unit should be set to NMEA 0183 input/
output messages. This standard requires your unit be set to the following:
GGA data string 4800 baud rate Timing - 1 second 8 data bits No parity 1 stop bit
Tip: If you have your GPS unit set properly and have checked the connection but still are not get­ting geo-referenced data, uncheck the box re­quiring the digital correction in Meter Settings (pp. 8 - 9) .
