Sourcing and reading dc like a milliamp or voltage calibrator, simulating and measuring T/Cs and RTDs like a temperature calibrator, and generating and counting frequency and counts-per-minute like a frequency calibrator are all possible with the CL329 Process Calibrator. It can also check continuity and measure ac line voltage like a multimeter. Users simply select a function and choose a range, then turn the knob for the precise output required. The instrument will store three output values per range for instant recall with QUIK-CHEK switch.
