Booting and Measurement
- Booting:
- Press the On/Off button to turn on the device.
- If no sample is present, it will display a dash.
- Avoid strong light when using outdoors to maintain measurement
accuracy. - Clean the sample plate and prism before dripping the sample
liquid. - Ensure stability during measurement.
- Ensure uniform temperature levels for instrument, environment,
and sample.
- Measurement:
- Clear distilled water and dry the sample plate.
- Drip 0.3~0.4ml of the sample, then close the cover for
measurement. - To get an average measurement, press the Read button for 2
seconds.
The Calibration
The meter supports pure water calibration. Follow these
steps:
- Drip 0.4ml pure water, then close the cover for
measurement. - To enter calibration status, press the CAL button for 2-3
seconds until ‘CAL’ flashes. - Press CAL button again during flashing to start
calibration.
Frequently Asked Questions (FAQ)
Q: What should I do if the instrument displays ‘CAL’
flashing?
A: Press the CAL button again during flashing to start the
calibration process.
Q: Can the digital refractometer measure highly corrosive
liquids?
A: No, it cannot measure liquids highly corrosive to metal or
glass.

Press “On/Off” button to turn on
If there is no sample,it will display “dash” Note : 1. When used outdoors,please avoid strong light
so as not to affect the measurement accuracy. 2. Before dripping into the sample liquid, please
clean the sample plate and Prism with soft clean cloth or soft paper. 3. Please keep the instrument in a stable status to measure. 4. Please ensure instrument, environment and sample are in the same temperature level before measuring. 4.2 Measurement After tum on,clear the distilled water and dry the sample plate, drip 0.3~0.4ml sample then close the cover to measure.

Cyclic Switch Measuring Result Press CAL once
Press the “Read” one time the meter will measure one time.
Showing Beyond Measuring Range
If press the “Read” button for 2 seconds, the instrument would make the automatic measurements upon programmed times (default 15times), the final value is the average of 15 times’ measurements, After measurements, it will return to the normal state and the scales display area would display the average of the automated measurements
The multifunctional area displays the number of remaining automatic measurements.For each automatic measurement, this number is reduced by 1.

5.The Calibration The meter only supports pure water calibration. The calibration method is as following:drop 0.4ml pure water then close the cover to measure.
LED Flashing Display
Press “CAL” button for 2-3 seconds till see the `CAL’ flashing .to enter the calibration status.
Press “CAL” button once again during the `CAL’ flashing to start to calibrate. When the calibration is completed showing as following. If no any operations for 10seconds the instrument would return back to booting status.
If fail to complete the calibration, multi-function display area would show an error code.
Display error code A03,indicating error of sensor measurement.See the appendix for other error codes .

We recommend calibrating the refractometer, when commissioning after a strong shock after longer transport after a change of location with a large temperature
difference if the device has not been used for a long time Always use distilled water and make sure that the refractometer, the water and the environment are at the same temperature.

7.Turn Off
1. After turn on if without any operations for 3 minutes, the instrument would be automatically turned off.
2. Press “on/ off ” button for 2-3 seconds, the instrument would be turned off.
8.Maintenance and Preservation
1. Please clean and wash the sample plate with distilled water and dry it with soft cleaning cloth or paper towel after finishing the measuring one kind sample.
2. Never left the remains and residuals of samples in the sample plate for long time.

3. After finishing measurements of the corrosive liquid, please clean the sample plate as quick as possible to avoid the irreparable damage of the prism and metal surface of the plate.
4. Please use soft cleaning cloth or paper towel to clean the sample plate to avoid scribing the prism’s glass.
5. When the dropper and dust-free cloth are not used, please clean it with clean water and put it in the packing box after drying.
6. If no using the instrument for a long time, please remove the battery, and preserved in a cool and dry environment.
