KERN OPTICS ORM-2CO Digital Refractometer Instruction Manual

KERN OPTICS ORM-2CO Digital Refractometer

INSTRUCTION MANUAL

Carefully read through the operating manual even if you have prior experience with KERN refractometers.

1. General information

1.1 Intended use

The refractometer is a measuring instrument for determining the refractive index of transparent substances in liquid or in some cases also in the solid state. It is used to observe the behaviour of light as it passes from a prism with known properties to the substance being tested.

Use of the refractometer for other purposes is contrary to its intended use and may be hazardous. The manufacturer shall not be liable for any damages caused by improper use.

1.2 Warranty

The warranty shall be void in the event of:

• Failure to observe the instructions in the operating manual
• Use for purposes other than those described
• Modifications or opening the device housing
• Mechanical damage and/or damage resulting from media, liquids, natural wear and tear

This digital refractometer cannot measure any liquid that is highly corrosive to metal or glass. When measuring liquids that are corrosive to plastics or react chemically with plastics, be careful not to drop the measured liquid onto the shell. Otherwise it will corrode the shell.

3.1 Description display & operating buttons

Note： Please replace the battery when the  is displayed.

4. Preparing before operating

4.1 Install the battery

5. Turn on & measure

5.1 Turn on

Note :

1. When used outdoors, please avoid strong light so as not to affect the measurement accuracy.
2. Please keep the instrument in a stable and still statement and position.

5.2 Measure

After turning on, clean the sample tank with distilled water and then dry it. Now fill the sample up to the mark, close the cover and press ” READ”.

5.3 Average value measurement

Press “READ” for 2 seconds. The device starts an automatic measurement series of 15 mea- surements and shows the average value. After- wards, the device automatically turns back to the normal measuring mode.

6. Calibration

The refractometer can only be calibrated with distilled water. To do this, fill the sample tank with distilled water up to the mark and close the cover.

While “CAL” is flashing in the display, press “CAL” again to start the calibration. When the calibration is finished, the display shows “End”. After approx. 10 seconds, the device automati- cally returns to normal mode.

7. Changing scale & termperature unit

7.1 Changing scale

7.2 Changing termperature unit

If exceed the temperature limitations, the signs “HHH” or “LLL” would show.

8. Turning off

If without any operations for 1 minute, the instrument would be automatically turned off.

9. Cleaning & maintenance

1. To avoid damages to the prism and the sample tank, clean them with distilled water after each use.

2 . Dry it with a soft cloth afterwards.
3 . Do not use hard or abrasive objects for cleaning.

4 . Do not leave any residue in the sample tank.

5. If the refractometer is not going to be used for a longer time, remove the battery and store it at a cool and dry place.

10. Disposal

The packaging consists of environmentally friendly materials which can be disposed of via local recycling facilities.

The device and storage box should be disposed of by the operator in accordance with applicable national or regional regulations at the place of use.

NOTE: In accordance with the Battery Ordi- nance (BattV), batteries must not be disposed of in householdwaste. The end user is legally obliged to return them.

FAQ

Q: Can this refractometer measure highly corrosive liquids?

A: This digital refractometer cannot measure liquids highly corrosive to metal or glass. Be cautious with liquids corrosive to plastics as they may damage the shell if spilled.

Q: How do I calibrate the refractometer?

A: To calibrate, follow the instructions in the manual.
Typically, it involves adjusting to a known reference standard.

Q: What should I do if the measurement result is outside the range?
