Today I've done a quick check on my existing DMMs. Absolute interesting - all three multimeter are showing an excellent accuracy compared to each other - independent of their age!
An old Nordmende -TR-6355 which basically was manufactured by Takeda Riken in Japan. This one is for sale here.
|2.2527 V||2.25 V||2,25 V|
|0.29876 V||0.298 V||0.299 V|
|16.787 V||16.78 V||16.79 V|
|40.993 V||40.9 V||41.0 V|
|49.694 V||49.6 V||49.7 V|
|23.677 mA||23.7 mA||n.a.||The Fluke 12 has no current measurement capability|
|56.63 mA||56.7 mA||n.a.|
|1.047 A||1.05 A||n.a.|
|2.01 Ohm||1.9 Ohm||2.2 Ohm|
|508.32 Ohm||507 Ohm||509 Ohm|
|4.673 kOhm||4.64 kOhm||4.68 kOhm|
|462.6 kOhm||460 kOhm||463 KOhm|
As can be seen in the numbers, even the old Nordmende DMM shows an excellent accuracy - not more than +-2 digits compared to the Fluke 289 - excellent these guys have used first-class components - lets see, how the new Fluke behaves after such a long time!
