The CMM Precision Process Multimeter offers simultaneous source and measurement of current and voltage, along with measurement of temperature, frequency, duty cycle, pulse width, and resistance with up to 0.03% accuracy. The meter features rms measurements of non-linear voltage and current loads and is programmable for 16 continuous or timed step outputs or 999-step ramps. The meter's large, dual (4000/40,000-count) backlighted LCD shows the primary and secondary source and/or measured values and functions selected. The unit can source bipolar current of ±25 mA and voltage of ±1.5V, ±15V with a constant current output for loads up to 500W. A built-in isolated RS-232 interface with optional Windows software provides advanced data acquisition and documentation functions.
