Note:
To maintain accuracy whenever outside this temperature range, apply the
relevant temperature coefficient adder.
Settling Time: ---------- Less than 2 seconds to within 10ppm of 0.25µV
Drive Capability: ------ 15mA max. (50
output impedance below 220mV, 0.1
above 220mV)
Overload: --------------- Output fully protected against short-circuits
Long-Term Effects: --- Add 25ppm of output to 1 year specification for 3 year
accuracy
DC Current Output Specifications
DC current output is available in both the 2000I, 2000M, 2000IN and the
2000MN instruments. Refer to Table 8.
