Setup

Before using your M100+, you will need to familiarize yourself with the instrument’s operating modes and functions and perform some setup, configuration and calibration.

The M100+ allows for the measurement of the turbidity of water. The turbidity of the water is usually reported in Nephelometric Turbidity Units (NTU) but may be reported in Formazin Nephelometric Units (FNU). This is user selectable.

Readings up to 4400 are possible but readings above 4000 are outside of the rated specifications. Readings above 4400 NTU will cause the display to flash, indicating an over-range condition.

During normal operation the instrument will be at the HOME screen.
This is the screen where measurements can be viewed.

Please note, some features depicted in this manual may change with future firmware updates.

Operating Screens

There are four main operating screens in the form of icons, Home ( ), Trend ( ), Calibration ( ) and Setup ( ). Touch the appropriate icon to switch between screens.

Home Screen
The Home screen is the normal reading screen. This is the default mode when power is applied or restored. The other three operation screens are limited to 15 minutes with no key presses. After 15 minutes, the screen will return to Home.

Trend Screen
The Trend Screen is used for displaying trend information. This information can be downloaded to the USB stick or printed to a serial printer.

Calibration Screen
The Calibration screen is used for calibration. The instrument was calibrated and tested prior to leaving the factory. Therefore, it is possible to use the instrument out of the box. Under normal conditions, re-calibration is required once every three months. Quarterly calibration ensures performance within accuracy specifications.

Setup Screen
The Setup screen is where configuration changes can be made. In the Setup screen, you can customize the instrument according to needs and preferred operation at any time during normal operation.

Calibrating the M100+

The instrument was calibrated and tested prior to leaving the factory, so it is possible to use the instrument directly out of the box. Under normal conditions, recalibration is required once every three months. Quarterly calibration ensures performance within accuracy specifications.

The EPA and ISO recommend that on-line turbidimeters used for reporting purposes be calibrated with a primary standard at least once every three months.

Calibration Standards

If the M100+ will be used over the entire range of 0.02 to 4000 NTU, a complete calibration as described below will be required, which includes two High Range standards.

If the instrument accuracy is only required below 1000 NTU, a calibration may be performed using the 1000 NTU standard, the 10 NTU standard and the 0.02 NTU standard. To calibrate starting at 1000 NTU, simply press the 1000 button on the calibration screen.

If the instrument accuracy is only required below 10 NTU, such as for potable water, a calibration may be performed using only a 10 NTU and a 0.02 NTU standard. To calibrate starting at the 10 NTU, simply press the 10 button on the calibration screen.

We recommend that the following materials be used during calibration to achieve the full-scale accuracy stated in this manual. All calibration standards listed below are available for purchase from HF scientific.

• High Range A ProCal Calibration Standard
• High Range B ProCal Calibration Standard
• 1000 NTU ProCal Calibration Standard
• 10.0 NTU ProCal Calibration Standard
• 0.02 NTU ProCal Calibration Standard

Diluted Formazin is unstable. If Formazin is used to calibrate the instrument, ensure that a fresh stock suspension of Formazin is used to achieve the accuracy quoted for the instrument. A Formazin Stock Solution Kit (catalog no. 50040) is available from HF scientific.

The HF scientific ProCal (Primary Calibration Standards) are more stable than Formazin and have a minimum shelf life of 12 months. For more information on ordering HF scientific’s ProCal Standards, see Accessories and Replacement Parts List later in this manual.

Prior to recalibration, review the expiration dates to ensure that the standards have not expired.

Care of ProCal Standards

The information below is provided as general guidelines for proper care of ProCal standards.

• Standards should only be handled by the top, black cap or by the very bottom of the cuvette.
• Keep cuvette glass clean of fingerprints and debris.
• Cuvettes can be cleaned with any domestic glass cleaner and the provided microfiber cloth.
• Prevent ProCal standards from freezing. This will most likely destroy them.
• Standards under 100 NTU must be freshly poured from the supplied bottle as they are not stable in the glass cuvette.
• There is no need to shake standards, but standards over 1000 NTU should be up-ended gently before use.
• Replace standards at the expiration date.

Indexing Calibration Cuvettes

To achieve the greatest accuracy and account for normal scratches and aberrations in cuvette glass when calibrating, HF scientific recommends indexing the cuvettes.

Standards and standards kits purchased from HF scientific are supplied with indexing rings. Complete instructions on how to index cuvettes are included in the calibration kits.

Indexing is best performed if the automatic reading is enabled and set to 1 sec/reading. See Auto/Manual Readings section for more information. The following steps allow repeatable indexing of calibration standards.

1. With the instrument in the home screen, insert the standard.
2. Slowly rotate the standard inside the optical well one complete turn (360°).
3. While rotating the standard slowing, observe the measured turbidity and locate the position of the cuvette having the lowest reading.
4. With the calibration standard positioned at the location having the lowest turbidity reading, install the indexing ring over the cap on the standard so that the pointer of the indexing ring faces directly forward.

When using the standards in the future, always insert the standard so that the pointer of the indexing ring faces forward. Slowing rotate the standard back and forth about 5° to find the lowest point. The standard is now indexed and ready for use.

Calibration Procedures

To calibrate for 0-4000 NTU using ProCal, you will need the following standards:

• High Range A
• High Range B
• 1000 NTU
• 10 NTU
• 0.02 NTU standards

To calibrate for 0-4000 NTU using Formazin, you will need the following standards:

• 4000 NTU
• 1000 NTU
• 10 NTU
• 0.02 NTU

Prior to beginning calibration, clean the calibration standard cuvettes with a microfiber cloth and standard window cleaner. Take care to only handle standards by the black cap to prevent fingerprints or smudges from affecting the readings.

1. Select the calibration function by pressing the Calibrate icon.
2. Select the appropriate calibration standard (Formazin or ProCal) and then press to save the selection.

A calibration for only 10 NTU requires only the 10 NTU and 0.02 NTU standards. Press the 10 NTU button on the left side and start at step 8 of the previous section.

For the two alternate ranges, these will still read the full range with a reduced accuracy above the range of calibration.

Failed Calibration

In the case of a failed calibration, the last good calibration is restored once the user exits to the Home screen. A failure will be evident when the calibration screen shows all red.

The instrument can be used with this calibration with a potentially reduced accuracy. The bad calibration will be noted in the calibration log and as a reminder, a yellow diagnostic banner will show on the home screen. The yellow banner indicates that the last calibration had failed and that the instrument is using the previous calibration. The only way to remove this indication is to successfully complete a calibration.

Check the standards for cleanliness. If everything looks good, attempt the calibration again. If the calibration fails after the second attempt, the most likely cause is that the standards are bad or the lamp needs replacement.

In the event of such defects within the warranty period, the Company will, at its option, replace or recondition the product without charge. Parts which by their nature are normally required to be replaced periodically, consistent with normal maintenance, specifically reagents, desiccant, sensors, electrodes and fuses, are excluded. Also excluded are accessories and supply- type items. Proof of purchase from the Company (Company invoice or paid order confirmation) and/or first use (commissioning) must be provided when making a product warranty claim.

THE WARRANTY SET FORTH HEREIN IS GIVEN EXPRESSLY AND IS THE ONLY WARRANTY GIVEN BY THE COMPANY WITH RESPECT TO THE PRODUCT. THE COMPANY MAKES NO OTHER WARRANTIES, EXPRESSED OR IMPLIED. THE COMPANY HEREBY SPECIFICALLY DISCLAIMS ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OR MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

The remedy described in the first paragraph of this warranty shall constitute the sole and exclusive remedy for breach of warranty, and the Company shall not be responsible for any incidental, special or consequential damages, including without limitation, lost profits or the cost of repairing or replacing other property which is damaged if this product does not work properly, other costs resulting from labor charges, delays, vandalism, negligence, fouling caused by foreign material, damage from adverse water conditions, chemical, or any other circumstances over which the Company has no control. In addition, the Company shall not be responsible for any costs incidental to the Company’s warranty response efforts, including, without limitation, costs associated with the removal and replacement of systems, structures or other parts of facilities, de-installation, decontamination and re-installation of products, or transportation of products to and from the Company. This warranty shall be invalidated by any abuse, misuse, misapplication, improper installation or improper maintenance or alteration of the product.

Some states do not allow limitations on how long an implied warranty lasts, and some states do not allow the exclusion or limitation of incidental or consequential damages. Therefore the above limitations may not apply to you. This Limited Warranty gives you specific legal rights, and you may have other rights that vary from State to State. You should consult applicable state laws to determine your rights. SO FAR AS IS CONSISTENT WITH APPLICABLE STATE LAW, ANY IMPLIED WARRANTIES THAT MAY NOT BE DISCLAIMED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO ONE YEAR FROM THE DATE OF ORIGINAL SHIPMENT
