The correct operation of metal analysis instruments
1. Connect and power the instrument Connect the mains power socket to the mains with the power cable, and ground the instrument reliably (otherwise it will be easily disturbed and cause data fluctuations); Check if the drain hose is firmly installed (do not put the outlet of the liquid hose) Dilute into the waste liquid, so as not to discharge the liquid, and inject distilled water (reference liquid) into the cuvette and turn on the power switch of the instrument. At this time, the instrument displays the unit name and date, accompanied by sound, and press the cursor keys to move Cursor, enter the year, month, and day. And press the confirm button to end; if you do not need to modify, you can directly press the confirm button to enter the sample test interface.
Second, zero input and fullness adjustment In the daily use of the instrument, it is necessary to adjust zero and full-scale work.
The zero point usually does not need to be adjusted frequently, and you can enter the sample test interface by pressing the zero key each time you turn on the instrument.
When the fullness is adjusted, adjust the channel fullness adjustment knob at the position of the cursor on the sample test interface so that the signal percentage is displayed as about 100.0. Press the full scale button again, and the full scale will be tracked to 100.0 0.1. Follow the steps above to adjust. The fullness of other channels.
The full-scale adjustment can also be performed in the standard calibration interface. When the cursor is in the T display line in the target calibration interface, the full-scale key is pressed, and the full-scale is traced to 100.0 0.1.
Third, the sample test and print 1, in the sample test interface, the cursor default in the first channel position.
2, first add a good reference solution, adjust the zero, full scale.
3. Press the cursor keys to cycle through the cursors in each channel.
4. Press the number key (0-9) to call the corresponding curve (Article 0-9).
5. Discard the reference solution and add the color solution of the sample. The value shown in the sample is the percentage of the sample. The value shown in the sample is the transmittance, and the value shown in the sample is the absorbance.
6, press the print number (1-4) key to confirm, print the relevant parameters of the corresponding channel, press print 0 to confirm, print the relevant parameters of the four channels at the same time.
7. Follow the above steps to complete related measurements for other channels.
8. Press the query key to enter the query modification interface.
9, press the target / test button to enter the target calibration interface.
Second, zero input and fullness adjustment In the daily use of the instrument, it is necessary to adjust zero and full-scale work.
The zero point usually does not need to be adjusted frequently, and you can enter the sample test interface by pressing the zero key each time you turn on the instrument.
When the fullness is adjusted, adjust the channel fullness adjustment knob at the position of the cursor on the sample test interface so that the signal percentage is displayed as about 100.0. Press the full scale button again, and the full scale will be tracked to 100.0 0.1. Follow the steps above to adjust. The fullness of other channels.
The full-scale adjustment can also be performed in the standard calibration interface. When the cursor is in the T display line in the target calibration interface, the full-scale key is pressed, and the full-scale is traced to 100.0 0.1.

8. Press the query key to enter the query modification interface.
9, press the target / test button to enter the target calibration interface.
