The Keithley 2000-20 E 6.5 Digital Multimeter at 220V is a high-resolution measurement instrument combining a 6.5-digit multimeter with an integrated 20-channel scanner card for multi-point data acquisition. It delivers 0.002% basic accuracy on DC voltage measurements and supports a full suite of electrical measurements including voltage, current, resistance, frequency, temperature, and diode testing. The instrument achieves up to 2000 readings/second at 4.5-digit resolution with internal buffering, or 50 triggered readings/second at full 6.5-digit resolution over IEEE-488 GPIB. The 20-channel scanner employs latching electromechanical relays with <3.5 ms actuation time and supports both 2-pole (20 channels) and 4-pole (10 channels) switching configurations. Designed for research, development, and production environments requiring synchronized multi-channel measurement capability.
