So I recently purchased an Excelvan M6013 Capacitance Meter and was checking some new capacitors out. I was a little displeased that my previous favorite brand (lets call them Brand R) consistently read at least 10% below the factory rating and a few were barely in range at 20%, These are all new caps that are under two years from when I bought them from a major supplier. The Brand "N" and Brand "P" caps all read pretty close to the manufacturer specs. Is this normal? Wondering why a famously high quality brand test so poorly. Thanks.

Re: New meter, surprising results.
what series rubycons are you testing?
i want to repeat the test

all ZLx series i pull from stuff reads under, i never thought it was like that from new though.Comment

Re: New meter, surprising results.
What meter do you have?Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.
My computer doubles as a space heater.

I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue... -
Hi
I want to change the scale of an analog meter, to monitor the charge of an li-ion single cell, so the needle at the end would point 4.2 volts and the 0 on the meter would point 2.5 volts or so, i tried to add diodes or a zener in series with the meter but the changes of the ambient temperature also changes the voltage value on the meter
I wonder how i can accomplish this so the meter would be precise at any temperature ?

Greetings, new guy here but always interested in the crazy universe of modding
We just finished construction of around 25 vacation houses, all inside the same private area.
Each house has 3phase power , and we bought an atlas MK10 meter for each house (25 meters total ! )
The metering on a per-house basis is done privately. Its not done by a utility company. The utility company will only charge us for the total consumption of all 25 houses together.
Id like to do a small modification on the firmware of our MK10 to make it easier identify each house's...05-20-2025, 09:09 AM -
Most analog meters are actually current driven - a current is needed to deflect the pointer full scale. They can be lots of different values. There are ones that can take several amperes to swing the pointer as they have internal shunts.
On the other hand there are many that are rated in microamps for the intent that they draw as little power as possible from the devices under test. Some are 1mA, 500µA, 200µA, 100µA, and the ubiquitous 50µA frequently used in analog VOMs. There are even 20, 25, 30 µA and even down to 10µA. Been collecting a bunch of different ratings and... -
I have had this in my wish list for quite a while now and I might need to test BMS protection board with this device because of the limitations of the battery testing machine that I have been using
https://www.aliexpress.us/item/32568...yAdapt=glo2usa
What this will allow me to do is use my load testing machine that is having issues with the voltage cutoff set/ current meter monitoring system and I decided not to try to replace it or repair it I just going to use a very primitive load testing...
