I won't start a new thread, so I'll post here:
I have a Sanwa 5000A meter, I bought it used a few years ago, it worked flawlessly. He tinkers sometimes, so I used it to calibrate some voltage measurements carried out with the help of Arduino, I tested the load on the charger for my own production batteries, etc ... Recently, when the power supply to the house failed, after restoring, instead of 230V, it showed me 350V. I called the power company and they show 230V with their meter. I lost my meter, time is up. I am considering buying a Rigol-class oscilloscope and once I heard that a seller, along with his oscilloscope, also offered a relatively good quality meter at a good price.
I am looking for a meter of a similar class, I care about the accuracy of the voltage reading (for measurements of a few V), automatic ranges, Auto-Off, if it had TrueRMS, and most importantly, that the measurements should be reliable. What would you recommend?
APPA meters - are they good? I saw an interesting model somewhere? And Unit-T? I considered this model with an 81C oscilloscope.
I also assumed the purchase of some simple model, with basic measurements, but it must have automatic ranges. Or buy anything for PLN 50 to have and calmly wonder what and where to buy? I planned to buy the Oscioscope itself in late autumn, but if there was an opportunity for some promotions, you can now.
