Keithley 199

The Model 199 is a 5.5-digit system DMM in a compact, half-rack package. The DMM features six standard measurement functions - DC and AC volts, DC and AC amps, ohms (2- and 4-wire), and dB (for AC volts and amps) along with the IEEE-488 interface.

More Performance, Maximum Utility

Sensitivities are 1uV, 1mOhm, and 100nA with 60 ppm basic 90-day accuracy in DC volts. AC voltage accuracies are good to <1% of full scale, much better than competitive units. Enhancements include a digital FILTER for noise reduction and a ZERO function to subtract offsets or make measurements referenced to a specific baseline.

The Model 199’s functions and features can be pre-set for power-up, and the display can be programmed with operator
messages.

Fast—Where it Counts
The Model 199 has the speed for a high performance test system. It can be externally triggered to meet system timing requirements at up to 150 readings/second with 4.5-digit resolution. By storing the readings in its 500- point memory, the controller from real-time data collection.

Stand-Alone Data Logging
Use the Model 199 to track drift or other trends. The 199 can be programmed to automatically store up to 500 readings at intervals from 15ms to 16.6 minutes (over 5 days of data), or by external trigger.
