5. DESCRIPTION 5.1. GENERAL DESCRIPTION AND INTENDED USE The HI97715 is an auto-diagnostic portable meter that benefits from Hanna's years of experience as a manufacturer of analytical instruments. It has an advanced optical system that uses a Light Emitting Diode (LED) and a narrow band interference filter that allows for accurate and repeatable readings. The optical system is sealed from outside dust, dirt and water. The meter uses an exclusive positive-locking system to ensure that the cuvettes are placed into the holder in the same position every time. With the CAL Check functionality, users...

Press and hold to power off/on. Press briefly to return to the previous screen. Press to access the menu screen. Press to display the context-sensitive help menu.

5.3. PRECISION AND ACCURACY Precision is how closely repeated measurements are to one another. Precision is usually expressed as standard deviation (SD). Accuracy is defined as the closeness of a test result to the true value. Although good precision suggests good accuracy, precise results can be inaccurate. The figure explains these definitions. For each method, the accuracy is expressed in the related measurement section. 5.4. PRINCIPLE OF OPERATION Absorption of light is a typical phenomenon of interaction between electromagnetic radiation and matter. When a light beam crosses a substance,...

Instrument Block Diagram The internal reference system (reference detector) of the HI97715 photometer compensates for any drifts due to power fluctuations or ambient temperature changes, providing a stable source of light for your blank (zero) measurement and sample measurement. LED light sources offer superior performance compared to tungsten lamps. LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability. LEDs are available in a wide array of wavelengths, whereas tungsten lamps...

GENERAL OPERATIONS 1. Press CAL Check key from measurement mode. The "Not Available" message or the date/time and status of the last CAL Check will be displayed on the screen. 2. Press the Check key to start a new CAL Check. Press the ~ key at any time to abort the validation process. 3. Use the ▲ ▼ keys to enter the certificate value of the calibration standard found on the CAL Check Standard Certificate. Press Next to continue. Note: This value will be saved in the instrument for future validation. If a new set of calibration standards is obtained please update the certificate value. 4. Insert...

- "OUT OF SPECIFICATION": A user calibration is not allowed, the measured value is outside of the tolerance window. Check the certified value, expiration date and clean the outside of the cuvette. Repeat the CAL Check procedure. If this error continues contact your nearest Hanna Customer Service Center. 6.2. CHEMICAL FORMULA / UNIT CONVERSION Chemical formula/unit conversion factors are pre-programmed into the instrument and are method specific. In order to view the displayed result in the desired chemical formula enter menu by pressing = and use the ▲ ▼ keys to select Chemical Form. Press Select...
