IMPORTANT SAFETY INFORMATION
This analyzer is compliant with safety standards as outlined in:
European Community low voltage directive (EN 61010-1)
Please read and observe the following:
•Opening the analyzer door exposes you to line power voltage, if present, at terminals TB5 and TB6 in
the base of the enclosure. This may be hazardous. Always remove line power before entering this area
in the analyzer. However, the analyzer door assembly contains only low voltage and is completely safe
to handle.
•Install this analyzer in accordance with relevant local codes and instructions contained in this operating
manual. Also, note and comply with 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.
•Whenever it appears that analyzer safety is questionable, disconnect line power from 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 140°F (60°C).
•Only qualified personnel should perform wiring or repairs, and only when the analyzer is not powered.
HELPFUL IDENTIFIERS
In addition to information on installation and operation, this instruction manual may contain
WARNINGS pertaining to user safety, CAUTIONS regarding possible instrument malfunction,
and NOTES on important, useful operating guidelines.
WARNING:
A WARNING LOOKS LIKE THIS. IT WARNS YOU OF THE
POTENTIAL FOR PERSONAL INJURY.
CAUTION:
A CAUTION LOOKS LIKE THIS. IT ALERTS YOU TO POSSIBLE
INSTRUMENT MALFUNCTION OR DAMAGE.
☞
NOTE: A note looks like this. It alerts you to important, useful
operating information.

Definition of Equipment Symbols
This symbol means CAUTION and alerts you to possible danger or
instrument malfunction. Refer to this manual before proceeding.
This symbol, which appears on the analyzer enclosure at the green
ground screw (shown in Figure 2-3), means that this is a protective
ground terminal and alerts you to connect an earth ground to it.
This symbol on the equipment means that there is alternating cur-
rent present and alerts the user to be careful.

CONDENSED OPERATING INSTRUCTIONS
This manual contains details for all operating aspects of the instrument. The follow-
ing condensed instructions are provided to assist you in getting the instrument
started up and operating as quickly as possible. These condensed instructions
are only for basic operation. To use specific features of the instrument, refer to
the appropriate sections in this manual for instructions.
A. CONNECTING SENSOR
1. After properly mounting the analyzer (PART TWO, Section 2), connect the
GLI Differential Technique pH sensor to “SENSOR”terminals on TB1 (Fig-
ure 2-3), matching colors as indicated. When using a conventional
combination pH electrode, follow the instructions in PART TWO, Section
3.2 to connect it.
NOTE: For GLI Differential sensors that have two shield wires, always
connect its outer shield to the green ground screw (earth ground)
and its inner shield to “SHLD”Terminal 6.
2. Configure the analyzer for the type of sensor being used:
A. Press the CONFIG key to display the “CONFIGURE”menu screen.
B. Use the
Ø
Ø
key to select the “Main Parameter”line, and press ENTER
key to display the “MAIN PARAMETER”submenu screen.
C. With the “Sensor Type”line selected, press ENTER key to display the
“SENSOR TYPE”submenu screen.
D. Use Õ
Õ
or Ö
Ö
key to choose the appropriate selection:
•DIFF for GLI Differential Technique Sensor
•COMB for conventional combination pH electrode
With the selection highlighted, press ENTER key to enter it.
B. ADJUSTING DISPLAY CONTRAST
Ambient lighting conditions may make it necessary to adjust display contrast to
improve visibility. With the MEASURE screen displayed, press and hold the
ENTER key and simultaneously press the ×
×
or Ø
Ø
key until attaining the desired
contrast.

CONDENSED OPERATING INSTRUCTIONS
C. CALIBRATING THE ANALYZER
The analyzer must be calibrated so that measured values will correspond to
actual process values. The analyzer provides different methods for calibration.
For the first-time calibration, however, it is highly recommended to use the
two-point arbitrary buffer method described below:
1. Press the CAL key to display the “CALIBRATION”menu.
2. With the “pH”line selected, press ENTER key to display the “pH
CALIBRATION”submenu screen.
3. With the “Arbitrary Buffer”line selected, press ENTER key to start calibra-
tion using this method (analog output state selection screen appears).
4. With analog output selection screen displayed:
A. Use
Õ
Õ
and
Ö
Ö
keys to select “HOLD”to hold the analog outputs at their
present values during calibration. Outputs can also be transferred
(XFER) to user-preset values or allowed to remain ACTIVE.
B. Use
Ø
Ø
key to select “CONTINUE,”and press ENTER key to continue.
5. On subsequently appearing screens, follow the easy instructions and make
the appropriate selections to complete the calibration.
D. COMPLETING ANALYZER CONFIGURATION
The analyzer provides many useful features including analog and TTL outputs,
relays, optional PID controller, and software alarms. To configure these ana-
lyzer features to your application requirements, use appropriate CONFIGURE
submenus to make selections and “key in”values. Refer to PART THREE, Sec-
tion 5 for complete configuration details.
