HZ-3320D DC Winding Resistance Tester 20A 3 channels

Summary

DC resistance of transformer is one testing item which must be tested during ex-work test of semi-finished products and final products, installation, acceptance test and preventive test of electric power department, which can effectively find out material selection of transformer coil, welding, looseness of connection part, missing strand, broken wire etc manufacturing defect and existing hidden problems after operation. In order to meet rapid measurement demand of transformer DC resistance, HZ-3320D DC Winding Resistance Tester 20a 3 channels applies new power technology, which is characterized with small volume, light weight, big output current etc. The whole machine is controlled by a single chip microcomputer, which has automatic self-inspection, data process, display etc functions, it also has automatic discharge and discharge audio alarm and indication etc functions. Testing accuracy of instrument is high, operation is easy and simple, and it can realize rapid measurement of transformer DC resistance.

Tech Data

Common Problems And Solution Methods

1. Don't start and buzzer continues sound

Firstly check whether power supply is connected with AC380V or voltage of input power supply is too low under such condition.

2. Crystal screen can't be lit when machine is started.

Firstly check whether power supply is normal in case of this situation, then check whether fuse is broken. If it is broken, replace new fuse.

3. Liquid crystal screen for starting machine is lit but display is abnormal or not display

Firstly start again and press re-set key once under such condition.

4. Testing data isn't stable or error is too great

Firstly check testing wire whether it is virtually connected and loose under such condition. If it isn't still solved, check whether the sample is corroded.

5. Always display "Charging …." during testing process

Firstly exclude magnetic circuit problem of the transformer in case of this situation. If the current isn't changed for long time and it is always around zero, check whether there is short circuit phenomenon in the circuit. If current isn't always charged, check whether measurement scope is exceeded.

6. "Exceed measurement scope". If resistance value is greater than 50Ω during testing process, it will inform "Exceed measurement scope", the instrument will not stop testing, and it will continue display testing result. But the measurement result may be inaccurate, it belongs normal phenomenon.

7. "Overheat protection" Temperature may rise up because the power supply in the instrument works for long time or is damaged, it will inform "Overheat protection". Start the machine and don't carry out testing, let the air fan work for 10 minutes and let internal temperature drop down as soon as possible, and then carry out testing. If it can't be tested, power supply may be damaged.
