Ningbo Daheyi YG138 strip dryness uniformity tester has been favored by all walks of life in textiles since its launch, and its current market share is also relatively high. In order to ensure the normal use of the instrument and not affect the customer's production efficiency, I will now summarize the data anomalies encountered during the test, and you can refer to it.

Generally, when yarn tests are carried out, problems such as coarse details (coarse nodes + 50%, details-50%), number of neps (generally +200% in regular reports), large or small H value are usually found. When encountering these situations, we must first ensure the reliability of the instrument data of the YG138 strip uniformity tester, and then proceed to the maintenance of the faulty instrument. I have made a summary here, with the following points:

1. Whether the ground wire of the power supply part of YG138 type strip dry meter is grounded reliably and is separate from electromagnetic interference and high-power equipment (such as air conditioner and oven).
2. There is a matchbox-sized tensioner on the top of the spinning rack, also called a box-type tensioner, which is also a factor affecting the abnormal test data. There are two clamping plates inside the tensioner, and each of the two clamping plate bowls has a spring, which acts as a shock absorber when the tube yarn or bobbin yarn is unwound, and prevents excessive jitter of the yarn.
3. Detect the extension. For the YG138 strip uniformity tester that has been used for many years, the industrial control computer should be turned on regularly to remove dust to prevent the main board and the golden fingers of each board card in the chassis from getting damp, blackening and oxidizing.
4. If the above possibility is excluded, when the test data is unstable, the fault phenomenon should be solved by replacing the detection head and signal conditioning board.

YG138 strip evenness test analyzer is a particularly important testing instrument for controlling spinning quality. I sincerely hope that users and friends will make full use of it and maintain it.
