When the weight display is stable, press “↑†key, immediately press “Test†key, the instrument will start to measure moisture automatically. At this time, the indicator light of the moisture is on, and the data window shows the amount of water being lost. The temperature display value is rising until the set value. It is normal for the temperature display value to jump up and down 2-3 degrees in the measured moisture.
When the moisture measurement is completed, the instrument automatically stops heating and emits an alarm sound. Pressing the “display†key once will cancel the alarm sound. At this time, the judgement time is displayed. Press the "Display" button again and the instrument will display the final moisture value. If the instrument is connected to a printer, press the Print key directly to print the moisture value. Need to see other test parameters can be continuously press "display" in order to view, and finally press "clear" key to make the instrument back to the current weight state.
Lift the heater cartridge, remove the weighing pan using the bracket, place the spare weighing pan on the weighing bracket, and press the “Zero†button to set the instrument display to 0.000. After the other weighing pan is cooled, pour out the sample and clean it for the next moisture measurement. Chapter IV Calibration Operation
Calibration operation. Take the same sample, while measuring with the national standard method, according to the comparison between the measured value of the national standard method and the measured value of the instrument, adjust the instrument heating temperature and the determination time, the specific operation is as follows: If the measured value of the instrument is lower than the value measured by the national standard method, the increase is set Set the temperature or increase the discriminating time. If the measured value of the instrument is higher than the measured value of the national standard method, the set temperature value is lowered or the determination time is shortened. After repeated adjustments until the measurement error meets the requirements. In order to facilitate the adjustment of the proposed user to change the set temperature value without changing the determination time.
Due to the high resolution and high sensitivity of the instrument weighing system, vibration must be prevented during testing and the front of the instrument must not be placed in the wind.
   The “ Test†button must have the following three conditions when the “Test†button is active. First, the instrument is working in the current weight state. Second, the weighing value is greater than 0.5 g. The third is that the “↑†key has been pressed. Initial weight. Otherwise, pressing the "test" button will have no effect.
" Clear" key When the instrument is in any state, press the "clear" key, the instrument will automatically return to the "current weight" state. In the same way when measuring the state of water, press the “Clear†key, the instrument stops measuring the moisture and returns to the “current weight†state.
“ Print†key When the instrument is set to connect the printer working mode, after the determination of moisture is completed, press the “print†key to start printing the moisture value. If the instrument is not connected to the printer, you cannot press “print†key, otherwise the instrument will Will die, at this time must be powered off and reboot. . 5.5 SFY-20 calibration method Press "Calibrate" key, the meter displays "-20-", then put 20g weight on the weighing plate, wait for a period of time, about ten seconds, until the instrument shows the weight, At this point the calibration is complete. If the calibration value exceeds the error (±10 mg), you can recalibrate the above steps until the calibration value is reached. Calibration should be performed after the instrument is warmed up.
“↑†and “↓†multi-function keys Press “↑†key to increase the identification time, memorize the initial sample weight and function settings, press “↓†key to reduce the identification time and function setting. This two-button setting is not valid in the state of moisture measurement.
The “ Zero†key sets the zero range to 100% of the maximum weight value. If the display is not 0 in the instrument zero status, press this key to display 0 in the instrument. Chapter VI Precautions and Maintenance
 During the determination of moisture, vibration must be avoided. The notch in the lower end of the heating tube cannot be placed in the wind.
The sample must be flattened in the weighing pan. The accumulation area should be filled with the bottom of the weighing pan as much as possible. The stacking thickness should be as thin as possible to facilitate complete evaporation of water.
 In the process of determining the moisture, the heating cylinder cannot be touched by hand, and it is forbidden to knock or directly vibrate the worktable.
 Because the weighing system of the instrument is a precision device, especially the power transmission part is particularly afraid of heavy pressure and impact, so the bracket is used as far as possible when taking and placing the weighing disk. If you take it by hand, put the weighing disk to take it lightly. Lightly.
Immediately after the measurement is completed, the weighing plate must be removed with a bracket to prevent it from becoming hot. The bracket should not touch the weighing bracket and weighing plate when it is placed in the instrument.
After the measurement, the weighing plate must be completely cooled and then the next sample must be placed.
Before each measurement, the instrument weight display must be zero.
After the measurement is completed, the weighing pan is completely cooled and then cleaned.
 Maintenance +0 6.2.1 Regular verification according to regulations
When the equipment is decommissioned for a long time, the temperature adjustment door on the right side of the instrument should be closed, the components of the instrument cleaned, and then stored in a dry and non-corrosive atmosphere.
It is forbidden for non-professionals to disassemble the moisture analyzer.
