MODEL 660 GUARDED DC DIFFERENTIAL VOLTMETER INSTRUCTION MANUAL
■The Keithley Model 660 Guarded DC Differential Voltmeter is a convenient, self-contained potentiometric system that accurately measures dc voltages. It has 20.02% limit of error from 100 millivolts to 500 volts full scale, 0.005% repeatability, and a reference supply stable to 0.005% indefinitely without manual standardization. Maximum null sensitivity is ±100 microvolts full scale; resolution is within 2 microvolts.
■Features for convenient use include: five in-line readout dials with automatically lighted decimal points; 10 to 25-millivolt recorder output; input polarity switch; floating operation up to 500 volts off ground; fast overload recovery; better than 45 decibels of 60-cps rejection.
