Keithley 197 5.5 Digit Portable Autoranging Microvoltmeter
Description
The used Keithley 197A/72A/78 Portable Multimeter is a lightweight, portable DMM with a battery pack option. It combines 51/2-digit resolution (on a 220,000-count display)with 1µV, 1nA, 1mΩsensitivity. Basic DCV accuracy is 0.011%.
Measure voltage over nine decades from 1µV to 1000V. Input resistance on the two lowest voltage ranges exceeds 1GΩ. TRMS AC measurements can be made to 100kHz. Make 2- or 4-terminal ohms measurements over 11 decades from 1mΩto 220MΩ. Six current ranges measure from 1nA to 10A.
