2.2 Overview of product

DANGER

Potential danger with contact with chemical/biological substances. Working with chemical samples, standards and reagents can be

dangerous. Make yourself familiar with the necessary safety procedures and the correct handling of the chemicals before use and read and follow all relevant safety data sheets.

Normal operation of this device may require the use of chemicals or samples that are biologically unsafe.

• Observe all cautionary information printed on the original solution containers and safety data sheets prior to their use.

• Dispose of all consumed solutions in accordance with the local and national regulations and laws.

• Select the type of protective equipment suitable to the concentration and quantity of the dangerous material being used.

The LICO 690 and LICO 620 instruments are VIS spectral-photometers with wavelength ranges from 320 to 1100 nm. The instruments can perform a precise colorimetric analysis in accordance with ISO/ASTM standards with a single measurement and display the result in the form of classic color systems such as iodine, Hazen or Gardner color values. The instruments support multiple languages.

The LICO 690 is supplied with 26 color value calculations, while the LICO 620 is supplied with five color value calculations (Iodine color, Hazen color, Gardner color, Saybolt color and ASTM D 1500 color numbers).

General Information

The LICO 690 contains the following programs and operating modes in addition to the color measurement: single wavelength mode, multi-wavelength mode, wavelength scan and time scan mode. The digital measurements are displayed in the dimensional units of concentration, absorbance or % transmittance, making the LICO 690 universally suitable for lab analysis.

4. Turn on the power switch next to the screen to activate the power supply (Figure 1, page 14).

Note: If you do not intend to use the instrument for a long period, disconnect it from the power supply.

Note: Make sure the socket you are using is easily accessible.

Installation

3.5 Interfaces

The instrument has three USB ports and one Ethernet port as standard. They are located on the front and rear of the instrument (Figure 1 Figure 2, page 15).

The USB type A ports are used for communications with a printer, USB memory stick or keyboard. A USB memory stick can be used to update the instrument software.

The USB type B port is used for communications with a PC. The optional Hach Lange Online Data software must be installed on the PC for this use.

A USB hub may be used to connect several accessories at a time.

Note: USB cables must not be longer than 3m.

These USB ports permit data to be exported to a printer or PC and also allow the instrument software to be upgraded (refer to

section 6.1.2, page 87). The Ethernet port supports real-time data

transfer in local networks, LIMS systems or SC controllers. Only use a shielded cable (e.g. STP, FTP, S/FTP) with a maximum length of 20 m for the Ethernet port.

Table 1 Interfaces

Interfaces Description

USB (Type A) This USB port can be used to connect a printer, a USB memory stick or a keyboard.

USB (Type B)

3.6.2 Installation of cuvette adapter Z

Installation

Cell compartment (2) for:

The following cell types can be used in cell compartment (2).

• Without cuvette adapter Z in the cuvette compartment (2), you can insert 50 mm cuvettes.

• With cuvette adapter Z: 10 mm square cuvettes.

Note: These cuvettes must be inserted with cuvette adapter Z.

Note: In the event of severe contamination, you can replace the cuvette

compartment (2) (see chapter 7.3, page 100).

1. Open the cuvette compartment.

2. Insert cuvette adapter Z into the cuvette compartment (2) so

that the arrow on the cuvette adapter is pointing toward the cuvette compartment (1) (Figure 3).

5.1 Overview

5.1.1 Tips for using the touch screen

The whole screen responds to touch. To choose an option, tap with a fingernail, fingertip, an eraser or a specialised stylus. Do not touch the screen with sharp objects, such as the tip of a ballpoint pen.

• Do not place anything on top of the screen, to prevent damage or scratching on the screen.

• Press buttons, words or icons to select them.

• Use scroll bars to move up and down long lists very quickly.

Press and hold the scroll bar, then move up or down to move through the list.

• Highlight an item from a list by pressing it once. When the item has been successfully selected, it will be displayed as reversed text (light text on a dark background).

5.1.2 Use of the alphanumeric keypad

This display is used to enter letters, numbers and symbols as needed when programming the instrument. Unavailable options are disabled (grayed out). The icons on the right and left of the screen are described in Table 2.

The central keypad changes to reflect the chosen entry mode. Press a key repeatedly until the desired character appears on the screen. A space can be entered by using the underscore on the YZ_ key.

The mode for quantitative color difference between a reference (R) and a sample (P) in the three-dimensional color space (CIE L*a*b* or Hunter Lab). In this mode, an additional reference memory for up to 100 references is available.

Single wavelength readings are: Absorbance readings: The light absorbed by the sample is measured in absorbance

units. Transmittance reading (%): Measures the percent of the original light that passes

through the sample and reaches the detector. Concentration readings: A concentration factor can be entered to enable the

measured absorbance values to be converted into concentration values. In the Multi Wavelength mode, absorbance (Abs) or percentage transmittance (%T) is

measured at up to four wavelengths and absorbance differences and absorbance relationships are calculated. Simple conversions into concentrations can also be carried out.

The time scan records the absorbance or % transmittance at a wavelength over a defined time.

A wavelength scan shows how the light from a sample is absorbed over a defined wavelength spectrum. This function can be used to determine the wavelength at which the maximum absorbance value can be measured. The absorbance behavior is displayed graphically during the scan.

The "System Check" menu contains a number of options, such as instrument information, optical checks, instrument backup, service times, instrument update, settings for analytical quality assurance and lamp history.

Saved data can be retrieved, filtered, sent to a printer, memory stick or PC and deleted.

This menu is used to configure user-specific and/or process-specific settings: operator ID, date and time, security settings, saved data, sound, PC and printer and energy management.

A variety of modes may be selected from the Main Menu. The following table briefly describes each menu option.
