(6). Voltage load mode: between coil and iron core.
(7) OK/ Reject verify way: goods of its leakage current value higher than setting value is taken as reject. The software will give acousto-optic alarm accordingly.
2. Insulation resistance test
(1).Testing voltage: DC500V
(2).Testing range: 10～500MΩ
(3). Integrated accuracy: ±5.0%
(4).voltage load mode: between coil and iron core.
(5). OK/ Reject verify way: manual setting the low limit of insulation resistance, when the goods of its insulation resistance value lower than setting value is taken as reject. The software will give acousto-optic alarm accordingly.
3. cold resistance test
(1). Testing range:
 (a) 0.001-9.999 (resolution ratio 0.100 uΩ).
 (b) 1.000-99.99 (resolution ratio 0.010 mΩ)
 (c).100.0～999.9(resolution ratio 0.100 mΩ)
(2). Precision: ±0.5% auto temperature compensate, could be calculated to resistance value at 20℃
(3). Testing way: between winding and winding.
(4). OK/ Reject verify way: Program reads the testing value of winding and verify ok/reject
by comparison of upper and low reference value. The software will give acousto-optic
alarm accordingly.
4. Inter turns insulation test
(1). Testing voltage range: 100V～2800V
(2). Voltage Precision: ±3%
(3). Voltage adjusting mode(-M: manual adjust,-A: auto adjust).
(a). manual adjust: manual no-step adjust
(b). input testing voltage to the software, thus machine do automatic loading to the setting value through the test.
(4). Pulse rising time: 1.2μs
(5). Verify way:  Δs/s  Δf/f.
(6). Voltage load mode: testing each winding respectively
(7). OK/Reject verify way: Program reads the standard value of wave between turns, compare the testing wave to standard wave. The software gives acousto-optic alarm if beyond setting value.
5. motor rotation test
(1). Testing voltage range:  220V
(2). Voltage adjusting way:  220VAV voltage adjusting manually.
(3). Verify way:  CW, CCW or stop
(4). Voltage load mode: main phase and high gear.
(5). OK/ Reject verify way: Program reads motor rotation direction. The goods in different direction to the setting direction is taken as reject. The software will give acousto-optic alarm
6.no-load current test(design testing range and method as per customer requirement).
(1).testing voltage range: confirmed as per the voltage of testing motor(power supplied by customer);
(2).testing range: 0～5A～10A～20A～40A；
(3). Integrated accuracy: ±0.5%
(4).testing way: high gear, medium gear;
(5).OK/Reject verify way: when the no-load current higher than the setting value is taken as reject, The software will give acousto-optic alarm
7. no-load power test(testing range and way designed as per customer requirement).
(1).testing voltage range: confirmed as per testing motor voltage(power supplied by customer).
(2).testing range: 0～100W～500W～1000W～2000W；
(3). Integrated accuracy: ±0.5%
(4).testing way: high gear, medium gear;
(5). OK/Reject verify way: when the no-load power higher than the setting value is taken as reject, The software will give acousto-optic alarm
8. Locked current test(testing range and way designed as per customer requirement)
(1).testing voltage range: confirm as per testing motor voltage(power supplied by customer).
(2).testing range: 0～5A～10A～20A～40A.
(3). Integrated accuracy: ±0.5%
(4).testing way: read current of motor start.
(5). OK/Reject verify way: when the Locked current higher than the setting value is taken as reject, The software will give acousto-optic alarm
9. motor rotating speed test(testing range and way designed as per customer requirement)
(1).testing voltage range: 220V/50HZ,110V/60HZ(testing power supplied by customer)
(2).testing range: 0～3600 rpm
(3). Integrated accuracy: ±1%；
(4).testing way: optical fiber induction output.
(5). OK/Reject verify way: when the motor rotating speed higher or lower than the setting value is taken as reject, The software will give acousto-optic alarm
Main feature:
1.Each test items could be on or off randomly. Approval standard also could be set up randomly. The machine will give acousto-optic alarm for reject motor.
2.Auto statistics the quantity and qualified rate, reject motor statistics classification
3.Single station/double station can be chosen, with high utility and testing efficiency
4.Customer can do item programming automatically as per testing requirement.
5.System switch part use imported high voltage vacuum steel spring tube relay, withstand voltage 10000V,work test 100000000 times
