This chapter describes the accessories, operating environment, precautions, and operating check for person-
nel who operate the 6166. Read through this manual before use.
1.1 Product Overview
The 6166 is a DC voltage current source that adopts a PWM system in the reference voltage generation block.
The 6166 is ideal for the working standard capable of manual setting by keyswitches, 1000-channel memory
setting, and remote setting.
In addition, its thermal electromotive force output function allows thermometers to be calibrated easily by
entering temperature values.
