Long term stability: +/- 10 ppm per year
-
Resistances from 0.0001? to 10? are 4 terminals
-
Resistances from 100? to 10M? are two electrolytic copper terminals with 2 screws, one for current and one for voltage
-
The potential terminals are screwed with plug connection.
-
Current terminals are of electrolytic copper widely sizeable.
