QUICK START GUIDE

FOR CLARITY II TURBIDIMETER

1. Refer to Section 2.0 for installation instructions.

2. The sensor cable is prewired to a plug that inserts into a receiving socket in the analyzer. The cable also passes
through a strain relief fitting. To install the cable…

a. Remove the wrenching nut from the strain relief fitting.

b. Insert the plug through the hole in the bottom of the enclosure nearest the sensor socket. Seat the fitting in the

hole.

c. Slide the wrenching nut over the plug and screw it onto the fitting.

d. Loosen the cable nut so the cable slides easily.

e. Insert the plug into the appropriate receptacle on the circuit board.

f. Adjust the cable slack in the enclosure and tighten the cable nut. For wall/pipe mounting, be sure to leave suffi

cient cable in the enclosure to avoid stress on the cable and connections.

g. Plug the cable into the back of the sensor.

h. Place the sensor in either the measuring chamber or the calibration cup. The sensor must be in a dark place

when power is first applied to the analyzer.

3. Make power, alarm, and output connections as shown in section 3.0 wiring.

4. Once connections are secured and verified, apply power to the analyzer.

5. When the analyzer is powered up for the first time Quick Start screens appear. Follow the Quick Start Guide to
enable live readings.

a. A blinking field shows the position of the cursor.

b. Use the t or u key to move the cursor left or right. Use the p or q key to increase or decrease the value of a

digit. Use the p or q key to move the decimal point.

c. Press ENTER to store a setting. Press EXIT to leave without storing changes. Pressing EXIT also returns the

display to the language selection screen.

IMPORTANT NOTE:

When using EPA/incandescent sensors (PN 801080002EPA):

n DO NOT power up the instrument without the sensor connected
n DO NOT disconnect and reconnect a sensor while an analyzer is powered

If this is inconvenient or cannot be avoided:

1. Cycle power to the instrument after connecting the sensor or..

2. Perform a Slope Calibration or Standard Calibration routine after connecting the sensor. Following these guide

lines will extend the life of the incandescent lamp and avoid premature warnings and faults due to reduced

lamp life.

MODEL CLARITY II SECTION 1.0

DESCRIPTION AND SPECIFICATIONS

SECTION 1.0.

DESCRIPTION AND SPECIFICATIONS

• COMPLETE SYSTEM includes single or dual input analyzer, sensor(s), and debubbler

assembly

• CHOOSE U.S. EPA METHOD 180.1 or ISO METHOD 7027 compliant sensors

• RESOLUTION 0.001 NTU

• FULL FEATURED ANALYZER with fully scalable analog outputs and fully programmable

alarms with interval timers

• INTUITIVE, USERFRIENDLY MENU in seven languages makes setup and calibration

easy

Clarity II is a trademark of Emerson Process Management.

1.1 FEATURES AND APPLICATIONS

The Clarity II turbidimeter is intended for the determi
nation of turbidity in water. Low stray light, high stability,
efficient bubble rejection, and a display resolution of

0.001 NTU make Clarity II ideal for monitoring the
turbidity of filtered drinking water. The Clarity II
turbidimeter can be used in applications other than
drinking water treatment. Examples are monitoring
wastewater discharges, condensate returns, and clarifiers.

Both USEPA 180.1 and ISO 7027compliant sensors
are available. USEPA 180.1 sensors use a visible light
source. ISO 7027 sensors use a near infrared LED.
For regulatory monitoring in the United States, USEPA

180.1 sensors must be used. Regulatory agencies in
other countries may have different requirements.

The Clarity II turbidimeter consists of an analyzer,
which accepts either one or two sensors, the sensors
themselves, and a debubbler/measuring chamber and
cable for each sensor. The cable plugs into the sensor
and the analyzer, making setup fast and easy. Sensors
can be located as far as 50 ft (15.2 m) away from the
analyzer.

The Clarity II turbidimeter incorporates the popular
and easy to use Model 1056 analyzer. Menu flows
and prompts are so intuitive that a manual is practically
not needed. Analog outputs are fully scalable. Alarms
are fully programmable for high/low logic and dead
band. To simplify programming, the analyzer automati
cally detects whether an EPA 180.1 or ISO 7027
sensor is being used.

Clarity II is available in an optional configuration in
which the analyzer, sensor(s), and debubbling flow
cell(s) are mounted on a single back plate. The sensor
cables are prewired to the analyzer, so setup is
exceptionally fast and easy. All the user does is mount
the unit on a wall, bring in power and sample, and pro
vide a drain. To order this option, consult the factory.

2.3 INSTALLATION — DEBUBBLER ASSEMBLY

See Figure 23 for installation.

Connect the sample line to the inlet fitting. The fitting accepts 1/4inch OD tubing. See Section 2.6 for recom
mended installation of the sample port.

Attach a piece of 3/8 inch ID soft tubing to the drain fitting. The debubbler must drain to atmosphere.

NOTE

During operation, the debubbler is under pressure. A 0.040 inch (1 mm) orifice in the outlet pro
vides the pressure. Back pressure helps prevent outgassing, which can lead to bubbles accu
mulating on the sensor face resulting in erroneous readings. DO NOT EXCEED 30 psig (308
kPa abs) inlet pressure.

The amount of pressure in the debubbler can be estimated from the flow rate. See Table 21.

To control and monitor sample flow, a valved rotameter with fittings is available (PN 2410300). Attach the
rotameter to the debubbler outlet. The rotameter can also be used to increase back pressure on the debubbler if
additional pressure is needed to prevent outgassing.

2.4 INSTALLATION — SENSOR

Unscrew the nut on the side of the debubbler. Insert the sensor in the mouth of the measuring chamber. Be sure
the pin on the debubbler lines up with the hole in the sensor. Replace the nut. Remove the protective cap from
the sensor and screw the cable onto the receptacle. The plug and receptacle are keyed for proper alignment.

The sensor is rated to IP65 when properly connected to the cable. To prevent possible water damage to the
connector contacts, be sure the cable receptacle and the connector on the back of the sensor are dry when
connecting or disconnecting the cable.

2.5 SAMPLE POINT

Locate the sample tap to minimize pickup of sediment or air. See Figure 25. If possible, install a sampling port
that extends one or two inches (25  50 mm) into the pipe. Use ¼ inch OD rigid plastic tubing. Avoid soft plastic
tubing if possible. To reduce sample lag time, install the debubbler and flow chamber as close to the sample tap
as possible.
