It is applied to cotton yarn, woolen yarn, acrylic yarn and other blended yarns.
Features:
1. The machine is a double sides and single layer with convenient operation, reasonable transmission, compact construction and attractive appearance;
2. The perdurable stability of high quality spindle at the high-speed operation;
3. Two-step drive device make the force-enduring reasonable and the range of false twisting more wider;
4. The winding tension can be adjusted on the pre-take-up roller, therefore, it is also applied to winding of loose dyeing;
5. Pedal-braking system is more easy to operate, and the longevity of apron belt and spindle will prolong at the same time;
6. The bobbin bank will lift automatically when winding up and end breaking which can avoid the abrasion of fiber.

1, the instrument shell firmly grounded.
2. Accept the test product: Insert one end of the arrester into the high-pressure (H-end) seat, and the other end of the arrester with the low-voltage wire and the L-end. Or use the plug to pull the high-voltage lead out of the test sample, but must ensure that the high-voltage lead has sufficient insulation to the ground.
3, switch on the power, press the power switch, press the detection button, the internal warning lights after the self-test, the discharge lamp is light, the two header indication value is zero (± 1 words).
4. Reset: Press the reset button once, the alarm light is off, and the instrument enters the test standby state.
5. Detection: After pressing the detection button for about 1 second, the detector will automatically complete all MOA test items. The results are as follows:
1 If the alarm light is on, it indicates that the MOA has a bad contact inside, or the external wiring is not secure. After the discharge lamp is on, check the external wiring, or press the reset button after replacing the sample to perform the next test. .
2 If the alarm light is off, it indicates that the MOA has good internal contact. The detector automatically enters the measurement UlmA and Id and displays the test results on the two meters respectively. After the discharge lamp is on, the test is completed, and the test wiring is removed or replaced. Product for the next test.
3 Continuous detection, repeat Step 5
Zero adjustment:
There is a zero potentiometer below the voltmeter head and current meter head. Turn on the power switch of the instrument and the warning light is on. Hold the test button and hold it. Carefully adjust the potentiometer with a small screwdriver until the current meter indicates “0±1â€. Words "up to now.
0.75UlmA Calibration Set the calibration button to 0.75UlmA. Connect the test sample. Press and hold the test button. After reading the stable value U, release the test button. At this point, the meter indication value will quickly change to another stable value U1 (shorter settling time) and eventually become zero. Here U is the UlmA value of the sample and U1 is 0.75UlmA. If U1 is 0.75U, adjust the corresponding potentiometer on the circuit board and repeat U and U1 until U1 is equal to 0.75U. U1 = 0.75U. Once calibrated, the detector can guarantee measurement accuracy over a wide range without frequent adjustments. After the calibration is completed, the calibration knob is set to UlmA state and the detector returns to the measurement state.
Simple troubleshooting
When “[[[†or zero adjustment is not displayed in the current meter header, the current loop input protection stage op amp (CA3140E) ICl (equivalent to the fuse) is damaged. If the meter indication is not “zero†after replacement, Must be adjusted, see Article 5 "Zero". Replace IC2 with IC1.
Precautions
For the safety of you and your equipment, please read carefully the following:
1. The shell must be reliably grounded during the test.
2. The instrument has been calibrated before delivery. If there is no special situation, please do not calibrate it yourself. No irrelevant items are allowed to stack on and around the device panel during the test.
4. Please check the power supply voltage before starting up: AC 220V ± 10% 50Hz.
5. When replacing fuses and fittings, use the same model as the instrument.
6. During the test, please confirm that the device under test has been powered off and disconnected from other live devices.
7. The instrument is protected against moisture and oil.
