For measurements in the secondary of a power supply you don’t have to worry about cat iii or cat iv
-The magna Psu already has a meter, it should be checked for calibration but I see no reason to use another external meter
Every supply we got has a inbuild meter, nevertheless we use everytime a multimeter for controlling the voltage.
Background:
As mentioned in another thread before, I´m planning a testing place for pcbs.
We must test/adjust dc-link supervision circuits for example.
Thresholdvoltages could be going up to 1000Vdc, in future projects above 1000v.
In the past we realize the voltage by connecting supplies in series - I don´t want that anymore for safety reasons.
So I´ve ordered a single supply from Magna-Power , which could deliver 0-1500Vdc/1A.
Multimeter is needed for controlling the outputvoltage.
Brymen 867/869 ?
For that I'd grab some resistors and build a fixed x100 voltage divider* to attach to the output then use a 10V multimeter to measure it. Put it inside a well insulated box.
For private use, I would do it also.
At work, it´s a little bit "different"...
In the specifications it says Cat IV 1000V AC / 1500 V DC which I find confusing
The scaling reading - Will everyone at everytime keep in mind, that e.g. 1.450V means 1450V ? Or 14.50 ? Or 145.0 ?
You may say sure, why not - But I want to minimize possible problems.
Actually it seems there´s no alternative to the beha-amprobes, the linked UT-196 seems nowhere to get.

Interesting to see that the brymen can handle voltages over 1000v, but like it´s mentioned before, it is not specified so it won´t be calibrated.
