Selection Summary

R6144 advantages: high accuracy of 0.03%, low noise, fast setup time, support for 4-wire Kelvin, 160 step sequence, GPIB programmable; Maximum output of 32   V/160   mA; suitable for calibration sources and ATE testing of precision devices.

Attention: The 10 mV and 100 mV ranges only support two-wire output, resulting in greater load effects; Large capacity loads will prolong the establishment time; Attention should be paid to temperature drift, and high-precision measurement should try to control the ambient temperature as much as possible.
