Very good information. Thank u very much. If possible please give all resitance value and their position (and their function in different rnage) on pcb of this multimeter.
Aapka video lajawab hua hai per Mera ismein DC rechargeable system Kiya hai voltage adjust karke Diya fir bhi wrong voltage show kar raha hai kya problem ho sakta hai
hi. i am facing issue with metrasafe-20 , it is showing wrong voltages while i measure 7805 positive voltage regulator with variable load. Can anyone let me know the reason of variable voltage at the o/p of 7805
I have same multimeter same model lam facing problem like above countineous beep sound on continty mode without to sorting the probes. Other parameter also not proper no physical damage on component side l checked sliders are OK plguide me thanks
@@etechniques I have the same multimeter and it has now started giving high readings. It showed 1.85 volt when I measured a 1.5v AA cell and 1.7V on a 1.2V cell. How can it be fixed ?
@@narakumar3175that's how you fix it. turn the potentiometer to calibrate. you will need another multimeter which is accurate and possibly a variable power supply
AC voltage reading shown abnormal in DT9205A multimeter i.e. 230 volt instead of 280 volt and more volt shown. How to repair. Await video from your end and notification pl.
Check resistance and diode near voltage line and also white capacitor (low capacitance) usually these caps are in nano farad range or even pico farad near main ic on different multimeters. If these caps go bad they can give infinite beep sound, fading display (or ghosting), and blinking numbers
Sir I stick the black and red probes on my mastek multimeter in continuity mode the (000) digit doesn't come. and it does(004/012), please tell me if this is normal. And it doesn't come all the time, sometimes it does. Sir please reply
@@etechniques I once selected the continuity mode with the multimeter by mistake and applied DC current and it shut down immediately but since then this thing has been happening but all other values are fine. And continuity is working fine that's the only problem. Reply sir
@@etechniques yes .who can i put them back in the original organization.bcoz i dropped them.one more thing i can send you photos to see the avo from inside .sorry my English not good .thank you

May be the load consumes more current that why

Did you check the two fuse
Hello
what does the potentiometer on the back change?
For voltage calibration

I have exactly same problem. How to make a slide contact as i have no other okd multimeter
unfortunately there is no other option dear friend.. Sorry..
@@etechniques i made it . A thin plate of copper make as a slide contact.. thanks .
@@Sekhar_Home wow! 👍👍👍 Great
Sir how to caliberate mastech it shows resistance 0.7 ohm on it
.7 Ohm reading in 200-Ohm range is normal
Where will I get slider
I got from a broken old multimeter

Sir I stick the black and red probes on my mastek multimeter in continuity mode the (000) digit doesn't come. and it does(004/012), please tell me if this is normal. And it doesn't come all the time, sometimes it does. Sir please reply
Please check with a new probe. If the problem repeat again , may be the problem with its sliding contacts or wear and tear of the rotary switch .

@@Subham7426 oh oh.. is it!
@@etechniques What does this mean?
pls help my avo pines mixed up i wanna put them back .i dont know how?its Dt5802
Sorry I didn't get you clearly.
You mean trouble with rotary switch contacts?
@@etechniques yes .who can i put them back in the original organization.bcoz i dropped them.one more thing i can send you photos to see the avo from inside .sorry my English not good .thank you
@@user-gw1bq7rj6m please watch the video again You can see the all sliding contacts positions.
