Introduction

Thank you for purchasing UV/VIS Spectrophotometer, Optizen Series.

Optizen Series can be applied various elds from a simple examination like a water quality

analysis to a complex examination like a bio-chemical analysis. User can measure easier,

faster, and more accurate by convenient interface and auto-function.

In addition, user can check and control experimental results on the real time by OptizenView,

PC-Interface software of Optizen Series.

Using Manual

This manual includes the ways of system installation, Optizen operating.

The manual is composed of four parts, which are categorized upon the subjects; therefore,

user can search quickly the necessary parts.

Part II. Functions and Application

1. Turning on Switch

It is self-tuning about CPU & ROM, Wave Moter, Cell Moter, Filter Moter, W Lamp, D2 Lamp

and D2 Wave. Results of self-tuning indicate Ok or Error. Incase Error occurs at any step,

self-tuning is stopped. If you want to check next step, push [ENTER] button. Only everything

is OK, automatically move to Main Mode.

To get more stable data, please warm up the system about 30 minutes after turning on the

switch.

• CPU & ROM : Check CPU & ROM

• WAVE MOTER : Wavelength motor driving test

• CELL MOTER : Multi-Cell Holder driving test

• FILTER MOTER : Filter driving test

• W LAMP : Check the status of Tungsten-halogen Lamp

• D2 LAMP : Check the status of Deuterium Lamp

• D2 WAVE : Check the status of Deuterium Lamp Wave

5. Utilites

You can change setup by selecting number.

1) Cell Mode

You can setup about Cell Mode. Default is Multi cell Mode. If you want to use Single cell

holder, have to change cell mode to Single cell holder.

• Multi Cell Mode : Use 8 hole cell holder.

• Single Cell Mode : Use single Cell Holder.

2) Unit

To change unit, push number 2 then show up 12 concentration unit. After moving with Up/

Down button, conrm with [Enter] button then unit is changed. Default is CONC.

3. MAIN MENU (Selecting Mode)

※ Real time clock function is supported at only 2120UV plus

Move to measuring mode by selecting number key.

To move another mode after measuring one mode, comeback to this ‘Main Menu’ then select

number.

Even though mode is changing, measured data remain without saving until turn off Optizen.

On the upper left side is a title and on the upper right side shows data information, print

status, and the cell position status. The central screen shows the graphs or detail information

on the measured data. The bottom side of screen indicates explanation, command, and the

choice box for function.

4. Cell Moving Method

Cell Holder is designed to hold up to 8 Cells. Each Cell has number “B, 1, 2, 3, 4, 5, 6, 7” and

it is possible to move a cell upward and downward respectively by [UP], [DOWN].

Please keep in mind that the rst cell, “B” is assigned to put Reference Cell.

9) Calibration Mode (Secret Key:’9’)

Optizen has self-correction mode for wavelength and cell holder position. Wavelength

calibration mode checks the 0th order position of grating and the peak wavelength (656.1nm)

of Deuterium lamp.

- wp X : 0th order position

- lp X : # of step per 1nm

- cp : Cell Position

• Wavelength Tuning : Self-correction for wavelength.

• Cell Tuning : Self-correction for cell position.

• Manual Input : Input modied values of calibration parameter.

• Parameter Save : Save modied value.

• Calibratin : Select Calibration Method. (One Point or Two Point)

※ Warning : It is very strongly recommended that ONLY expert or fully trained staff

engineers operate these advanced applications. Fatal errors can be caused by

some incorrect operations.

3) D2 Lamp Save Mode

It automatically turns off the power of the D2 lamp that is not used by selecting number 3.

Incase this mode ‘ON’, D2 Lamp is off at our of wavelength range.

‘Wait a moment’ message is showed up at that time. A few seconds is need.

※The wavelength range of Optizen 2120UV spectrophotometer is from ultraviolet radiation

(190nm) to near infrared radiation (1100nm). For this, deuterium lamp and tungsten-

halogen lamp is used as a light source. Two lamps are changed each other automatically

in 350~470nm range.

4) LCD Contrast Control

It controls brightness level of LCD back light.

5) Lamp Change WL.

You can setup the wavelength for changing point of deuterium lamp and tungsten-halogen

lamp.

The range of the value that you can input is from 350nm to 470nm.

The default value is 370nm.

6) Initial Wavelength

You can set initial wavelength of Optizen. Incase set mainly used wavelength, you don’t need

to set wavelength every measuring time.

7) Clear Lamp Position

Clear Lamp position of W Lamp and D2 Lamp.

8) Set Date & Time (Only 2120UV Plus)

Real time clock function is supported at only 2120UV plus.

Measuring in Each Test Modes

2) Mode Setup

• Initialize Factor : Initialize all factor.

• Modify Factor : Can modify Slope and Intercept.

• Open Factor : Can open saved Factor by selecting number.

Open factor function is generated only saved factor existing.

3) Measure (Step by Step)

• With Multi Cell

1. Incase Push NEW W.L. [F1], you can see the top left side gure then input wavelength.

You can enter by 8 wavelengths.

2. Incase push CELL [F3], show up the top right side gure. You can select the cell to

measure with number key.

3. MEASURE [F2].

Part III. Measuring in Each Test Modes

1. ABS/%T/CONC

1) Initial Screen of Test Mode

The mode assigns the size of Wavelength and the position of a cell, then measures and

marks Absorbance, %Transmittance and Concentration.

• NO. : TEST No.

• C# : Cell number of each TEST

• W.L. : Wavelength of each TEST

• ABS : Absorbance of each TEST

• %T : %Transmittance of each TEST

• CONC : Concentration of each TEST

• NEW W.L [F1] : Input wavelength by maximum 8.

• MEASURE [F2] : Start measuring.

• CELL [F3] : Select the cell by ON or OFF cell number.

• DELETE [F4] : After measuring, this function shows up. You can delete all data.
