IMPORTANT SAFETY INFORMATION
This analyzer is compliant with safety standards as outlined in:
FMRC Class Numbers 3600, 3611, and 3810 (U.S.A.)
CSA C22.2 No. 142 and C22.2 No. 213 (Canada)
EN 61010-1 (European Community)
Please read and observe the following:
•Line voltage may be present at terminals on TB1 at the back of the analyzer enclosure. This may be
hazardous. Always remove line power before going near this area of the analyzer. The front bezel
assembly of the analyzer, however, contains only low voltage and is completely safe to handle.
•Wiring or repairs should only be performed by qualified personnel and only to an unpowered analyzer.
•Whenever it appears that analyzer safety is questionable, disable the analyzer to ensure against any
unintended operation. For example, an unsafe condition is likely when:
1) The analyzer appears visibly damaged.
2) The analyzer fails to operate properly or provide the intended measurements.
3) The analyzer has been stored for long periods at temperatures above 158°F (70°C).
•This analyzer must be installed by specially trained personnel in accordance with relevant local codes
and instructions contained in this operating instruction manual. Observe the analyzer’s technical
specifications and input ratings. If one line of the line power mains is not neutral, use a double-pole
mains switch to disconnect the analyzer.

CONDENSED OPERATING INSTRUCTIONS
This manual contains details for all operating aspects of the instrument. The following con-
densed instructions are provided to assist you in getting the instrument started up and
operating as quickly as possible. These condensed instructions only pertain to basic pH
measurement operation using a GLI Differential pH sensor.To measure ORP, or use a
conventional combination electrode or specific features of the instrument, refer to the appro-
priate sections in this manual for instructions.
A. CONNECTING SENSOR/CONFIGURING SENSOR TYPE AND TEMPERATURE ELEMENT
1. After properly mounting the analyzer (PART TWO, Section 2), connect the GLI 5-wire
Differential Technique pH sensor, matching wire colors to terminals as indicated:
Sensor Wire Colors Connect to SENSOR Terminal
Yellow #4 on TB3
Shield #5 on TB3
Black #6 on TB3
White #7 on TB3
Green #8 on TB3
Red #1 on TB4
2. The analyzer is supplied factory-set for use with the GLI 5-wire Differential Technique
pH sensor. When using a conventional combination electrode, you must change the
sensor type (see PART THREE, Section 3.2, subheading “SELECT SENSOR Type”).
3. The analyzer is supplied factory-set for automatic temperature compensation using the
NTC 300 ohm temperature element built into all GLI Differential sensors (except Model
6006P4-2000 high purity water pH sensor systems which use Pt1000 ohm RTD).
When using a sensor with a different temperature element, or if you want fixed
MANUAL temperature compensation, you must change the temperature element type
(see PART THREE, Section 3.2, subheading “Select TEMP ELEMENT Type”).
B. CONNECTING LINE POWER
Important: Follow instructions in PART TWO, Section 3.6 to connect line power to the analyzer.
C. CONFIGURING BUFFER TYPE/CALIBRATING THE ANALYZER
The analyzer must be calibrated so that measured values will correspond to actual process
values. Before calibrating for the first time, select the buffer value set that will be used.
Then, calibrate using the recommended “2 POINT BUFFER”method which will provide the
most accurate pH measurements.
1. The analyzer is supplied factory-set for the common 4.00, 7.00, and 10.00 pH buffers.
When using DIN 19267 standard value buffers you must change the buffer set (see
PART THREE, Section 3.2, subheading “SELECT BUFFER Set”).

CONDENSED OPERATING INSTRUCTIONS
C. CALIBRATING THE ANALYZER -- (continued)
NOTE: When using buffers that are not included in either of the analyzer buffer sets,
use only the “2 POINT SAMPLE”method for calibration. Refer to that sub-
heading in PART THREE, Section 4.2 for instructions.
2. Immerse the sensor in the first buffer (preferably pH 7). Important: Allow the sensor
and buffer temperatures to equalize. Depending on their temperature differences, this
may take 30 minutes or more.
NOTE: An in-progress calibration can always be aborted by pressing the ESC key.
After the “ABORT: YES?”screen appears, do one of the following:
•
Press ENTER key to abort. After “CONFIRM ACTIVE?”screen appears,
press ENTER key to display the MEASURE screen, and return the ana-
log outputs and relays to their active states.
•
Use
×
×
or
Ø
Ø
key to choose “ABORT: NO?”screen, and press ENTER key
to continue calibration.
Calibration Tip! If, at any time during calibration, the “2 POINT BUFFER:
CONFIRM FAILURE?”screen appears, press ENTER key to confirm. Then, use the
×
×
or
Ø
Ø
key to select between “CAL: EXIT”or “CAL: REPEAT”and do one of the
following:
•
With the “2 POINT BUFFER: CAL EXIT?”screen selected, press ENTER key.
Then, after the “2 POINT BUFFER: CONFIRM ACTIVE?”screen appears, press
ENTER key to return the analog outputs and relays to their active states
(MEASURE screen appears).
•
With the “2 POINT BUFFER: CAL REPEAT?”screen selected, press ENTER key
to repeat calibration of this point.
3. Press MENU key to display a “MAIN MENU”screen. If the screen is
not showing, use
Ø
Ø
or
×
×
key to display it.
4. Press ENTER key to display .
5. Press ENTER key again to display .
6. Press ENTER key again to display .
7. Press ENTER key again to “hold”the analog outputs and relays at their present states
during calibration. (Outputs can also be transferred to preset values or allowed to re-
main active.)

C. CALIBRATING THE ANALYZER -- (continued)
8. With the sensor in the first buffer and the screen displayed, press
ENTER key to confirm. While the screen is displayed, the analyzer
waits for the pH and temperature signals to stabilize, measures the buffer value, and
automatically calibrates this point. Thereafter, a screen like appears
for 5 seconds to confirm calibration of this point.
NOTE: Any time the “PLEASE WAIT”screen is displayed during calibration, you can
manually complete calibration of the point by pressing the ENTER key. How-
ever, this is not recommended because the pH and temperature signals may
not be fully stabilized, resulting in an inaccurate calibration.
9. After the screen appears, remove the sensor from the first buffer,
rinse it with clean water, and immerse it in the second buffer (typically pH 4).
10. Press ENTER key to confirm. While the screen is displayed, the
analyzer waits for the pH and temperature signals to stabilize, measures the buffer
value, and automatically calibrates this point. Thereafter, a screen like
appears for 5 seconds to confirm calibration of this point.
11. A “pH SLOPE XX.X mV/pH”screen appears, indicating a slope value to measure sen-
sor performance. The slope should be within 54 to 62 mV/pH for optimal performance.
12. Press ENTER key to end calibration (“2 POINT BUFFER: CONFIRM CAL OK?”screen
appears).
13. Re-install the sensor into the process.
14. Press ENTER key to display the active measurement reading on the “2 POINT
BUFFER: CONFIRM ACTIVE?”output status screen. When the reading corresponds
to the actual typical process value, press ENTER key again to return the analog out-
puts and relays to their active states (MEASURE screen appears).
This completes “2 POINT BUFFER”calibration. The analyzer is now ready to measure pH.
D. COMPLETING ANALYZER CONFIGURATION
To further configure the analyzer to your application requirements, use the appropriate
CONFIGURE screens to make selections and “key in”values. Refer to PART THREE, Sec-
tion 3 for complete configuration details.
