DC Voltage Current Source

6½-digit working standard suitable for calibration High-accuracy and highly stable with bipolar output

The 6166 is a DC voltage/current source that uses a PWM system in the reference voltage generation block for high accuracy, high stability and high resolution.
The DC voltage can be output over a wide range of ±10 nV to ±1199.999 V and the DC current over a wide range of ±1 nA to ±119.9999 mA. Especially with its high stability for DC voltage source of 25 ppm per 90 days (typical value), the 6166 can be widely used for calibration of highprecision digital voltmeters or analog indicator instruments or as a generation source for a variety of tests.
In addition, the 6166 has a built-in function to generate thermal electromotive force of thermocouples according to the JIS table, enabling easy calibration of thermometers and other instrumentation systems.
