Chroma 19035 series with 5 kvac / 6 KVDC high voltage output, meeting the withstand voltage of the winding component test requirements, the maximum output current can be up to 30 ma.IR insulation resistance test can measure the range of 0.1 M Ω to 50 g Ω, up to 5 kv voltage output.DCR dc resistance measurement of the basic specifications, in addition to measuring winding component can also be used as a safety pressure test before connection (contact) check.
19035 series has a Flashover (electrical Flashover), OSC (open circuit detection), and other powerful additional function, and can program voltage value, time parameter, etc., according to different feature, the object under test to prevent bad product easily through quality verification, enhance confidence in the test itself and the quality of the product.
The product application
19035 series for motor, transformer, heaters and other related winding component test requirements, the design of comprehensive safety tester.Most winding component has multiple sets of winding, such as the three-phase motor, double winding transformer, etc., using 19035 eight channel scan, no manual switch test point, a multipoint once testing is complete, save the test time and human cost.
19035 series provides the OSC and DCR function, test whether poor contact or yet to be tested in the process of the phenomenon of short circuit, motor and transformer winding component tests such as what happened when the contact problem, improve the testing quality and prolonging the life of the device under test.
For different test applications, 19035 series include:
- Motor, fan special: 19035 - M
- Simple type (micro motor) : 19035 - S
- Standard (switch, wire, transformer, electric heat pipe) : 19035
Measurement technology
Flashover Detection electrical Flashover Detection
19035 and other safety test instrument series has the same Chroma Flashover detection function.Flashover was due to the high electrical insulating material internal or surface produce electric discharge, the insulation characteristics of a loss of the original object under test, the formation of instantaneous discontinuity or discharge, resulting in carbonized conductive pathways or product damage.With leakage current bad decision often cannot be checked out.Must to test the voltage or current leakage rate determination of detection.So the Flashover detect one of the indispensable review project for the high pressure test.

Ground Fault Interrupt (GFI) body protection circuit
Safety test equipment must be able to have function automatically cut off when the operator to get an electric shock, is the GFI help improve human body circuit.As shown in figure, I can be obtained by the ammeter A1 and A2, respectively1And I,2;When the operator to get an electric shock, ammeter respectively different measured values, the difference is I1-i2= IH.When IH.Too high, that is judged to be poor GFI, and immediately cut off the output signal, to ensure the safety of the user.

The Open/Short Check (OSC) on Short circuit detection
OSC function to detect whether there is open circuit in the process of testing (poor contact) or short circuit (short circuit) object under test conditions.In case of open circuit phenomenon, in the process of testing can lead to bad product as fine products,In case of short circuit phenomenon, can be learned and early screening, reduce the harm of fixture device, save the test cost.
General pressure test the product is a capacitive (Cx), may be under normal conditions for decades between pF and number u F.In the event of connection circuit in circuit interface form tiny capacitance (Cc), generally less than 10 pf, and presents the overall capacitance is far lower than the normal product, and when the short circuit or close to the object under test short-circuit always will present electric capacity is much higher than normal, so can use upper and lower limit value of capacitance change whether connection is good.

High Speed Contact Check (HSCC) Contact inspection at a High Speed
High speed contact check function is a new research and development of Chroma detection technology.HSCC can quickly scan circuit contact object under test is normal.This new technology can let the withstand voltage test before contact check more rapidly than ever before.
DCR dc resistance second-line/four line test
Chroma 19035 series will DCR measurement (tier 2/4 wire) listed as one of the standard test item.Second line measurement is suitable for the DCR bigger measurement, four-wire measurement has higher accuracy, is suitable for the DCR small measurement.
Bring about DCR measurement schematic diagram
Temperature Compensation function (Temp Compensation)
Equivalent of smaller DCR value, the temperature difference caused by the problems often.Equivalent time measurement of temperature is not at the same time, the measurement of resistance will be different.So 19035 joined the temperature Compensation function (Temp Compensation), through the transformation of temperature coefficient, the DCR conversion for the standard temperature measurement value, reduce the effects of temperature difference.
Dc resistance balanced judgement (DCR Balance)
DCR value is often associated with feeling quantity balance.When the DCR imbalance of three groups of motor winding, lead to unbalanced rotation, after long-term use can cause poor quality.DCR maximum minimum balance will determine winding is presupposed, exceeds the set value range is the bad product, is the motor product reliability test of auxiliary tool for a long time.
The product application
Motor/dc fan electrical test
Dc fan motor, such as a rotary motor of semi-finished products, including the stator and rotor two parts, all need to withstand voltage, dc resistance, short circuit between the layers and other electrical scanning test.The 19035 - M无须计算机控制，单机提供DCR四线量测，以8组分离式测试端点(Drive和Sense分离)，让您可以一次扫描测试二颗待测物，提高生产产能。 通道CH 1, 2, 3, 5, 6, 7可设定为高压输出/关闭。通道 CH 4, 8 可设定为参考端/关闭。

Time measurement item function - winding more than test components
Manufacturers in order to withstand voltage test efficiency, often in parallel test as a solution.Parallel test, but can't correct upper and lower limit set current, lead to bad product outflow or ryohin keikaku sentence to bad product;And after bad to needs to test station, increase the station number and the cost.
To solve the parallel test of 19035 series provide time measurement function (sub - step).When production need parallel test, through the program editor, with bad (Fail) as a test item start conditions.Means when the test items from the main test (parallel), it will be for time measurement test (single), and can judge the bad product for which an object under test.This feature of the import, would considerably increase pressure test efficiency of production line.
Ex. :
Step 1: AC Hipot/pin1 to pin5, 6, 7
Sub step A: AC Hipot/pin1 to pin5
Sub step B: AC Hipot/pin1 to pin6
Sub step C: AC Hipot/pin1 to pin7
