From my observations about accuracy, that comes after testing old gear ( digital and analog ) VS the modern expensive one models.
The conclusion are that any well made old gear, it can handle nicely the Ohms law and the variations of it,
about Amperes or Volts.
Allot of complexity added in the new gear, with the addition of circuitry's like:
True RMS on AC / Frequency counters / Min-Max-Average/ Temperature / db / etc etc
All those functions demands, additional electronics that they should coming with,
lots of speed and accuracy, so to be called as acceptable.
What made me to test this little DMM, was the fact that now I own one enormous amount of hand-held DMM,
and I wanted to test it, so to make my mind if I will put it back on my ( travel light) toolbox,
or send it for recycling.
After all this tests, I got surprised of how well it responds even today,
and I am going to keep it.
Its stamped as CAT I 600V, and for such tasks its good to go.
If I do anything wild with it, like using it in other CAT higher categories,
I will had to blame my self, and not the DMM.
Another interesting observation, is that the PCB on the range switch,
its still like new, no signs of wear at the contacts or any damage.
( I got it back at 2000, and so it is active for almost 11 years,
but I do not remember the price that I payed for it)
