Hi This is Kishore Kumar. Most of my postings pertain to electrical safety awareness and safe practices along with demo's. You are welcome to consult me regarding electrical safety subjects like
Earthing (design, testing, improvement, maintenance), Insulation Resistance (testing, improvement), MCB sizing, Residual Current or differential current (RCCB) breakers (sizing, testing), Leakage current testing and remedial measures, HV dielectric withstand testing, Energy audit, Safe practises. Selection and Purchase of Meters and Testers etc.

SMPS or Linear adaptor? Which one is safer?
I need a meter to measure less than 200ma . Can you show like dc ma
Can I check DCma.means less than 200
You have to buy AC and DC leakage current meter. Read the specs and ensure that the model has DC feature before buying.
I been using the exact same multimeter for for y to thirty eight years and I have never had any problems and it has never let me down and I even test three phase supply with it as well as 240v single phase supply.
Agreed. But now components quality are compromised, especially caps.
Thank u very much sir
Sir good evening ❤
Speech error @7:25 to 7.35 - 4.6Amps NOT 5.6 Each division value is 0.1Amps NOT 0.2Amps
Sir neenga palayamadhri Tamila video podunga sir plz

Waco earth tester mein charging led on ni ho rha..
How to test smps sir
By using DC load bank and measure voltage.
Purchase link sir

Safety warning: Always discharge capacitors before testing and after testing using suitable resistors (another subject). A charged capacitor is like a bomb. Do not short capacitors.
Useful sir
Very useful sir
Sir best capacitor check meter best model
HTC CM 1500/1501
Very useful sir
If you can use it for a year then your lucky😂😂😂
நீங்கள் சொல்வது சரிதான்.. ஆனால் எந்தக் குறையும் இல்லாமல் 14 ஆண்டுகளாக உபயோகிக்கிறேன்.. 2 அல்லது 3 வருடங்களுக்கு ஒரு முறை புதிது வாங்கி விடனும்...ரூ 200 தானே.
But this is new purchased from Robu.in Sealed packing.
And what about the decal? For proper mounting it should be removed.
In this case suppose the voltage drops to 8.5 V or below @ 1 amps draw, means the adaptor cannot deliver full power and its useless, cheating by the manu. You can use automotive lamps as load instead of resistors.
Sir iwant ac capacitor check meter best and cheap which one you r choice
HTC CM 1500
Kishore sir very useful
Sorry sir romba nalla video podava illa ❤❤❤
Why sir long video
How many adopters you have killed?
Sir is this good. Can i purchase and what is the difference between htc emf523 and this
For this price we don't get calibration certificate.
Your N-E voltage seems a bit high like mine. Mine is around 6V in the evening and 1V in the morning. Is it okay?
OK Try wetting the earth pit.
You put primary side high current load like equal to 100amp .if 100/5 or 100/1 amps ct means you put more current in primary. 200w load not affected
Note that there is no raise in voltage. If you have ref source please post the link. We believe sun raises in the east and sets in the west!
Thank u Sir...❣
This is an accurate, tough and waterproof (IP 67) LCR meter. I recommend.
hi can you share your number
Well done sir 🎉🎉
Tum ho india me video bana rahe ho English me .hindi me banao
Valuable information ❤ well 😊
Nice sir thank u
I like the dual colour display feature. If the tested circuit parameters are OK, the display is green. If it senses faults like reverse polarity, missing earth then the display turns red. This ensures that we won't miss faulty circuits.
How much time will press the test button for reading
Until reading is stable.
Gud one sir ❤
How many second rotate hadle sir
Refer user manual. Normally 160rpm
Sir which side input or out put...for rccb
According to labelled diagram
Netural earth link aanulum light eariumeay sir...?
Sir iam felix from ooty...rcd available a sir please rate and details and rccb and rcd different sir
RCCB and RCD are same. About rate enquire in electrical shops.
Sir what happened when we set 10 ohms
Like multi meter display will show OL if the resistance value exceeds 10 ohms. If you mean "get" instead of "set" then 10 ohms is acceptable. Sorry for late response.
@@30mAkills I have get reading 01.8 is it good
@@Blathurkaran what's the resistance value of lead wires? Also study FOP method from AEMC/Fluke/Megger knowledge base which are freely available at their web sites. FOP graph will be useful. Hope this helps.
IR Testers or Meggers are widow-makers unless you follow the below safety precautions: 1. Always wear gloves. 2. Check the probes and leads visually for damages like cracks, frayed necks and exposed wires. 3. Ensure that the device or circuit under test is not energized. 4. After testing, discharge the residual voltage retained by the device (cables, motors and transformers due to capacitive effect) simply by grounding the device terminals for a minute.
Kishore ji, ur contact no. pliz need to talk to you about power plant equipments.
Meter price sir
Check in amazon
You can also destroy a multimeter by trying to measure volts when the probes are plugged into the amps port!

DUT: HTC CL 2054 Leakage current Clamp Tester. Purpose of video: Calibration of mA range. Verdict: Readings are within tolerance limits. Hence Recommended. Uses: Leakage current testers are commonly used for measuring leakage currents (differential) which are present in mA range in any electrical circuit or equipment, which cannot be sensed by normal clamp meters. At higher ranges say 1 amps and above the leakage tester can be used as normal clamp meter. Usage method for measuring leakage current: Clamp all current carrying and neutral conductor (if present) together between the jaws or only the earth wire of the circuit. Precautions: 1) The wires should be approximately at the centre of the jaws. 2) The jaws should be closed firmly without any gap. 3) Wear gloves for safety. Causes of Leakage current: Insulation failure, capacitance, filters, improper earthing, are some of the common reasons. Effects of leakage current: 1) Can cause nuisance tripping of RCCB's. 2) Fire. 3) Electrocution during monsoon. Audio Correction @ 6:39 = RCCB and not MCB

Don't do this if you don't have the guts😮 So we should not measure volts when the probes are plugged into the amps port. Great lesson.
