Introduction
This chapter describes the 2000I, 2000M, 2000IN and 2000MN DC power source
instruments and highlights their features and functionalities. The 2000 instru-
ments were introduced in 1989 to support the fields of Process Control, Calibra-
tion, and General Equipment Testing.
Product Description
The 2000I, 2000M, 2000IN and 2000MN products are portable, lightweight DC
power source instruments. Their capabilities include the generation of precision
bipolar DC voltages1; precision bipolar DC currents2; the high accuracy simula-
tion of a variety of thermocouple types with optional active cold junction com-
pensation; and measurement of voltage and thermocouple outputs. On a 2000
instrument, you may enter a scaling factor, an offset factor and a “units” text
string, which enables the calibration of four 20mA loops in the “actual” units and
scaling of the transducer. Optional IEEE488 or RS232 isolated interfaces further
enhance the 2000 instruments, allowing them to be used in varying applications.
The 2000I, 2000M, 2000IN and 2000MN 2000MN instruments use microproces-
sor and digital-analog conversion technologies to produce highly flexible, accu-
rate instruments with high reliability. The combination of HCMOS
microprocessor technologies with low-power precision analog circuitry yields a
long battery life while maintaining a lightweight rugged package and a 0.5ppm
analog output resolution.
Automatic internal calibration and simple front panel (covers on) external calibra-
tion maintain high accuracy. A comprehensive range of computational abilities
enable a variety of applications.
1DC voltage expands up to 22V and down to 10nV resolution
2DC current expands up to 22mA and down to 10pA resolution
