IMPORTANT SAFETY INFORMATION
This measurement system 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:
•Opening the analyzer door exposes you to line power voltage, if present, at terminals on TB2 and TB3
inside the enclosure. This may be hazardous. Always remove line power before entering this area in
the analyzer. However, the analyzer door assembly and the sensor contain only low voltages and are
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 measurement system must be installed by specially trained personnel in accordance with relevant
local codes and instructions contained in this operating instruction manual. Observe all technical
specifications of the system. 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 Accu4™Low-range Turbidimeter System.
The following condensed instructions are provided to assist you in getting the system started up and op-
erating as quickly as possible. These condensed instructions only pertain to basic turbidity
measurement operation. To use specific analyzer features, refer to the appropriate sections in this
manual for instructions.
1. CONNECTING SENSOR
After the T53 analyzer is properly mounted (Part Two, Section 2.5), connect the GLI Model 8320 low-
range turbidity sensor, matching wire colors to terminals as indicated:
Sensor Wire
Colors
Analyzers with
“B”Prefix Serial No.
Analyzers with
No Letter Prefix Serial No.
Inner Shield Grounding strip lug Terminal #11 on TB1
Red Terminal #12 on TB1 Terminal #12 on TB1
Violet Terminal #13 on TB1 Terminal #13 on TB1
Green Terminal #14 on TB1 Terminal #14 on TB1
White Terminal #15 on TB1 Terminal #15 on TB1
Yellow Terminal #16 on TB1 Terminal #16 on TB1

Blue Terminal #20 on TB1 Terminal #20 on TB1
Black Terminal #21 on TB1 Terminal #21 on TB1
Orange Terminal #22 on TB1 Terminal #22 on TB1
2. CONNECTING LINE POWER
Important: Follow the instructions in Part Two, Section 3.5 to connect line power to the analyzer.
3. 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.
4. CALIBRATING SYSTEM
Always initially calibrate the Accu4™Low-range Turbidimeter System to ensure accurate meas-
urement. Any time thereafter, you can conveniently check system calibration using an optional
accessory Cal-CubeTM assembly.
•When you need to calibrate with a
primary standard, use the “PRIMARY CAL”calibration
method. GLI only guarantees measurement accuracy when a 40 NTU formazin suspension is used
as the primary standard.
•When calibration need not conform to USEPA requirements, use the “CUBE CAL”calibration
method (requires optional GLI CAL-CUBE™assembly) or the “SAMPLE CAL”method.
Refer to Part Three, Section 5 for instructions on all calibration methods.
5. 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, Section 4 for complete configu-
ration details.
