Notes | This is a 4-terminal resistance standard; 10000 ohm 0.03 amp rated at just over 10 watts. Two of the terminals have Dymo-tape labels ("IO." and "II."), probably the current-input terminals; the other two are unmarked but are probably the voltage-sensing terminals. It also has a shield terminal, a recess for a thermometer and a plunger with knob (used to agitate the internal coolant to ensure even temperature distribution). The unit is also marked in red paint with "F.A.T." (Factory Acceptance Test) |
