Appendix A–Output Specifications
The DC voltage and current output capabilities of the 2000I and the 2000M
instruments are provided here. Additionally, specifications for the 2000M
instrument’s of thermocouple measurement and simulation option are
included here.
DC Voltage Output Specifications
The accuracy figures given in Table 7 are valid throughout the temperature
range of 18º to 28ºC. The 24 hour stability figures are for constant load and
temperature (within 1ºC) and are measured using a DC to 2Hz bandwidth.
The accuracy figures are relative to calibration standards. Add 3ppm + 1µV
to the voltage figures for absolute accuracy.
