Fluke 189 Digital Multimeter

0.025% basic DC accuracy
50,000-count resolution with instant readings enables detailed analyses
100 kHz ac bandwidth opens the possibilities of modern applications not possible with less capable DMMs
Internal memory allows for stand alone logging of measurement changes (up to 3 days) indentifying stable and unstable periods with a real-time stamp.
MIN MAX to record and timestamp values in real-time.
250 µS Fast MIN MAX for peak transient capture.
Temperature readings in ºC or ºF using optional K-type thermocouple
Enhanced ranges, such as dc voltage measurements down to 10 µV, and capacitance up to 50,000 µF
Multiple reading display with bargraph has two-level backlight
The Fluke 187 and 189 both have on-line logging capabilities when connected to a PC. The 189 has the additional cabability of logging 995 readings in a stand-alone application for later download to a PC.
