Section 3 Installation

CAUTION
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the document.

3.1 Install the battery

WARNING
Explosion hazard. An expired battery can cause hydrogen gas buildup inside the instrument. Replace the battery before it expires. Do not store the instrument for long periods with a battery installed.

WARNING
Potential fire hazard. Use only alkaline or nickel-metal hydride batteries (NiMH) in the meter. Other battery types or incorrect installation can cause a fire. Never mix battery types in the meter.

NOTICE
The battery compartment is not waterproof. If the battery compartment becomes wet, remove and dry the batteries and dry the interior of the compartment. Check the battery contacts for corrosion and clean them if necessary.

NOTICE
When using nickel-metal hydride (NiMH) batteries, the battery icon will not indicate a full charge after freshly charged batteries have been inserted (NiMH batteries are 1.2 V versus 1.5 V for alkaline batteries). Even though the icon does not indicate a complete charge, 2300 mAH
NiMH batteries will achieve 90% of instrument operation lifetime (before recharge) versus new alkaline batteries.

NOTICE
To avoid potential damage to the meter from battery leakage, remove the meter batteries prior to extended periods of non-use.

The meter can be powered with AA alkaline or rechargeable NiMH batteries. To conserve battery life, the meter will power off after 10 minutes of inactivity, the backlight powers off after 30 seconds. This time can be changed in the Power Management menu.

Note: Rechargeable batteries will only be recharged with the USB/power module.
Refer to the module documentation for further information.
For battery, installation refers to Figure 3.

1. Remove the battery cover.

2. Install 4 AA alkaline or 4 AA nickel metal hydride (NiMH) batteries.
   Make sure that the batteries are installed in the correct orientation.

3. Replace the battery cover.

Section 7 Advanced operation
7.1 Calibrate the turbidimeter with StablCal Standards

Note: For best accuracy use the same sample cell or four matched sample cells for all readings during calibration. Insert the sample cell in the instrument cell compartment so the diamond or orientation mark aligns with the raised orientation mark in front of the cell compartment.

1. Push the CALIBRATION key to enter the Calibration mode. Follow the instructions on the display.
   Note: Gently invert each standard before inserting the standard.

2. Insert the 20 NTU StablCal Standard and close the lid.
   Note: The standard to be inserted is bordered.

3. Push Read. The display shows Stabilizing and then shows the result.

4. Repeat Steps 2 and 3 with the 100 NTU and 800 NTU StablCal Standard.
   Note: Push Done to complete a 2 point calibration.

5. Push Done to review the calibration details.
   

6. Push Store to save the results. After calibration is complete, the meter automatically goes into the Verify Cal mode. Additional information is available on the manufacturer’s website.
   

7.2 Reading modes

1. Push the UP or DOWN key to enter the Reading Options menu.
2. Select Reading Mode to select one of the following options:

Option Description
Normal (Default setting) The normal mode reads and averages three readings. The result is shown after the reading.

caused by the drifting of sample particles through the light path.
The X-bar icon is shown on the display when signal averaging is on.
The Signal Average mode measures 12 times and starts to show the average after three readings. The final result is the average of all 12 readings.
Rapidly Settling Turbidity (RST)| The Rapidly Settling Turbidity (RST) mode calculates and continuously updates the turbidity reading of the sample to a confidence of 95%, based on the accumulated trend of the real-time measured values.
The RST model is best used on samples that settle rapidly and continuously change in value. The reading is based on a correctly prepared sample that is homogeneous at the beginning of the reading. It is best applied to samples that are greater than 20 NTU. The sample must be mixed thoroughly by inversion immediately before inserting it into the meter.
The target icon is shown on the display when the
Rapidly Settling Turbidity is on.
The Rapidly Settling Turbidity reads and calculates five readings while showing intermediate results.

Section 8 Maintenance

CAUTION
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the document.

8.1 Clean the meter
The meter is designed to be maintenance-free and does not require regular cleaning for normal operation. Exterior surfaces of the meter may be cleaned as necessary.

Note: Do not clean the meter with solvents to avoid damaging the material.

1. Clean the meter with a dust- and lint-free dry or slightly damp cloth. A mild soap solution can also be used for liposoluble contamination.
8.2 Apply silicone oil to a sample cell
Sample cells and caps must be extremely clean and free from significant scratches. Apply a thin coating of silicone oil on the outside of the sample cells to mask minor imperfections and scratches that may contribute to light scattering.
Note: Use only the provided silicone oil. This silicone oil has the same refractive index as the sample cell glass.

1. Clean the inside and outside of the cells and caps by washing with a laboratory glass cleaning detergent. Follow with multiple rinses with distilled or demineralized water.

2. Apply a small bead of silicone oil from the top to the bottom of the cell.

3. Use the provided oiling cloth to spread the oil uniformly.
   Wipe off the excess so that only a thin coat of oil is left.
   Make sure that the sample cell is almost dry with little or no visible oil.
   Note: Store the oiling cloth in a plastic storage bag to keep the cloth clean.

8.3 Store the sample cells

NOTICE
Do not air dry the sample cells.
Note: Always store the sample cells with caps on them to prevent the cells from drying.

1. Fill the sample cells with distilled or demineralized water.
2. Cap and store the sample cells.
3. Wipe the outside of the sample cells dry with a soft cloth.

8.4 Replace the battery

WARNING
Explosion hazard. An expired battery can cause hydrogen gas buildup inside the instrument. Replace the battery before it expires. Do not store the instrument for long periods with a battery installed.

WARNING
Potential fire hazard. Use only alkaline or nickel-metal hydride batteries (NiMH) in the meter. Other battery types or incorrect installation can cause a fire. Never mix battery types in the meter.
For battery replacement refer to Install the battery on page 7.

1. Remove the battery cover.

2. Remove the batteries.

3. Install 4 AA alkaline or 4 AA nickel metal hydride (NiMH) batteries.
   Make sure that the batteries are installed in the correct orientation.

4. Replace the battery cover.

8.5 Replace the lamp
CAUTION
Burn Hazard. Wait until the lamp cools down. Contact with the hot lamp can cause burns.
