I recently purchased a Boonton 8210 modulation meter, and have two questions about its operation. At turn-on, the display shows "12.88" for a few seconds, then "CAL". Does any one know the reason for the "12.88" display? Also - this unit has Option S/3, which places 2 AAA batteries inside the unit, connected to the "digital/PS" board. The military tech manual mentions this option, but does not explain it. Any ideas?

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 ?

About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well
Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for
Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer... -
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
