测试前的准备工作：1、 清洗取样杯、搅拌棒和取样针头2、 擦干净取样窗

Preparation before testing: <br>1, sample cup clean, stirring bar, and sampling needle <br>2, a sampling window and the sampling wipe the table <br>3, the boot (boot automatic self-test and the instrument) <br>4, the screen automatically transferred after the completion of self-test. the main interface <br><br><br>5, taken cup clean purified water were placed sampling station, slowly lift the sampling needle sampling station about 1cm from the bottom of the sample cup position, without the influence of the stirring stopped, several functions can be tested enter the test, which is line cleaning apparatus may also be entered (cleaning function) cleaning <br>tests:

Pre-test preparation:<br>1. Cleaning sampling cups, mixing rods and sampling needles<br>2, wipe clean sampling window and sampling table <br>3, power on (after power ing on the instrument automatically into the self-test state) <br>4, the instrument self-test after the screen automatically transferred to the main interface<br><br>5, take a cup of clean purified water to place the sampling table, slowly lift the sampling table so that the sampling needle from the bottom of the sampling cup about 1cm position, stop without affecting stirring, enter the test function several times, this is the cleaning of the instrument line, can also enter (cleaning function) cleaning<br>Test:

Preparation before test:<br>1. Clean the sampling cup, mixing rod and sampling needle<br>2. Clean the sampling window and table<br>3. Power on (after power on, the instrument will automatically enter the self-test state)<br>4. After the instrument self check is completed, the screen will be automatically adjusted to the main interface<br>5. Take a cup of clean purified water and place it on the sampling table, slowly lift the sampling table to make the sampling probe about 1cm away from the bottom of the sampling cup, stop without affecting the mixing, and enter the test function for several times. This is the cleaning of instrument pipeline, and also can enter (cleaning function) for cleaning<br>Test:<br>
