Ⅲ Operating instructions

1． Preparation for measuring

When plug power line and testing line, opening the power switch on “1”, and the display and indicator lamp will be on. The display will shown “GW2100” (matches with GW2100) or “GW2100R” (matches with GW2100R) at one minutes later, the display shown“OPEN” (The state of measurement turns) or “-OU-”(The state of measurement resistance) after it flickers for about 15min. In order to test the instrument accurately, it should to be preheating 15min

2． Preferences(Only GW2100R)

To select test content according with actual measurement and the key of “PARA” can be pressed to conversion between turns test and DCR Test.

3. Measuring of turns

3.1 Select method of alarm setup (this selected method only applicable to the testing of turns, when testing the DCR, select this method is invalid);

Selections of message ring correspond respectively with the key” Phase”,” turnoff”, “silent” and matching indicator lamp. If the corresponding set testing happens in measurement, the inside hummer will go on ringing and inform the testers about the respective alarm.

When the phase key is pressed and the corresponding phase light is on, it suggests that the windings tolerate the phase. Interrupted alarm rings when the opposition is -

Press the key” turnoff”, the corresponding indicator lamp on, it is shown that the tested winding is turnoff (open). Otherwise, the interrupted alarm rings when it fails to connect, at the same time the “turnoff” lamp is on at the upper left of the instrument.The display will shown “-OPEN-”in testing open anytime;

Press the key” silent”, the corresponding indicator lamp on, the alarm still rings as it short.

3.2 Measuring of turns:：

To running the tumbler of transducer to propriety location (the corner ≦45^o) in counter-clockwise direction and to set the testing winding into the turns test transducer what is vertical to the instrument plane, then running the tumbler of transducer to close the vertical transducer in clockwise direction and then connect the testing clips and testing winding, the value what the display shown is the practice turns of testing winding value. Repeat above process and test next winding.

6．DCR test (Only GW2100R）

Press the” PARA” key into the state of measurement of resistance, and the display shown—OU—.

6．1 Clear：

The testing clips is short as following drawing, press the “clear” key to clear the base data what it is be applied in measurement resistance.

6.2 Measuring of resistance:

To connect the testing resistance into testing line, the instrument will automatic select span according with the size of resistance value and The LED digital display shown the testing value; select the measurement of resistance after turns testing finished, and can read out the copper resistance of measurement winding. The tested winding will not be set into winding test transducer in measurement of resistance.

Ⅳ Notice

1． Dot not lay the instrument near to the larger field, it will effect the normally test of instrument

2． If the testing winding has short by itself, it will affect precision.

3． The testing winding will be laid in centre of transducer to avoid affecting the test precision of the instrument.

4． Don’t through the test line into transducer; it will affect the results of testing

5． The testing line is wearing parts, if the instrument do not have nicely measure or do not test normality, please check the testing line break off whether or not, bad connection or the other failure.

6． The testing element should put and down lightly, to avoid impacting transducer, the rocker of transducer running should not exceed 45^O and running the rocker of transducer with high power should damage the transducer forever.

7． To protect transducer in transporting and handling the instrument.
