Varistor are used to protect a circuit from high voltage surges. Circuit can function without varistor but no protection. Just take out the faulty varistor & test. Cheers!
@@LifeBeginsAtForty I have SurgeProtector Extension Box - it has MOV (210Joules) soldered. Can i test that MOV in Soldered State OR i should remove it and test it? (Extension box not connected to power)
@@LifeBeginsAtForty It has no PCB. It is a 4 Socket Extension Box. They directly soldered MOV between 2 LONG&THIN COPPER STRIPS which connects all 4 (1st STRIP LINE - 2nd STRIP NEUTRAL).
You may check/test without taken out the varistor. Make sure not connected to supply & load when do checking. Good varistor should read no continuity using multimeter.

I dont speak your language but in this video you demonstrated the difference between good and bad varistors perfectly. Well done and thank you
actions speak louder than words, cheers!
the varistor can try on the pcb or need to remove?
Remove from PCB.
Terima kasih Cikgu. Penjrlasan sngt lancar straight to the point tiada larut2 leret2. Sya sdh subscribe channel Cikgu.
Terima kasih
terbaek..penjelasan dgn tutorial yg sgt jelas..👍
Terima kasih

So if I understand when checking for ohm OL means it is good and any resistance means it is bad?
Exactly
well that sucks 😕
Picofarads was showing as "victofarads" in the subtitles 😂
I don't create the subtitles, it is auto generated by UA-cam.
@@LifeBeginsAtForty I know. I just thought that was funny.
Terima kasih pak, untuk pelajaran nya

Hi bos...varistor jika test ade bacaan sekejap selepas tu tiada bacaan kira rosak ke mcm tu?
Blh tlong tnjuk cara test ceramic high voltage capasitor masih elok atau tidak...trm ksh

Cara nk tau varistor untuk peti sejuk mcm mna? Saya punya dh burn tk nmpk code
Kalau nak yang sama rujuk pada PCB yang elok atau rujuk kepada schematic (jika ada).
bagaimana pula varistor dgn thermistor . adakah fungsi sama atau berbeza. adakah cara cek juga sama atau berbeza?

Varistor saya tertera 472M,,,apa saya bisa mengganti dengan 222M
472M/222M itu ceramic capacitor & bukan metal oxide varistor (MOV).
Terima kasih buat ini video
Sama-sama, semoga bermanfaat.
WHY do you use an ENGLISH description but the spoken language is NOT????????? Clickbait????
Many thanks 👍
You are welcome
Terima kasih, penjelasannya baik sekali 👍
Terima kasih kembali
Kalau di pcb board ada lambang berbentuk "Z" adakah simbol utk varistor nie???
Ya, MOV = metal oxide varistor
@@LifeBeginsAtForty tapi varistor saya nie bentuk mcm GDT (gas discharge tube),pergi cari dekat kedai elektronik pun dorg xtawu..😅😅😅😅
Mine has indeed gone bad then, can i put a regular capacitor in temporarily?

Can i test that MOV in Soldered State OR i should remove it and test it? (Extension box not connected to power)
Renove one terminal from pcb & check/test.
@@LifeBeginsAtForty It has no PCB.
It is a 4 Socket Extension Box.

Boleh ke uji dekat board?
Boleh tapi lebih tepat jika dikeluarkan dari papan litar atau buka satu terminal dari pcb.

@@aboothahiru6354 NTC is a thermistor. The resistance is 5Ω at 25°c.
@@LifeBeginsAtForty I get 4.9ohms under room temperature so it is working thermistor

please dont use english titles for forein spoken videos, be realistic !!
Agree
It's in settings. What are you talking about? Change it uf you don't like it.
Get out from here, shuh
damn got wong video no english
Summary, no continuity on a good varistor and the capacitance reading are stable.
@@LifeBeginsAtForty many thanks.
