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.

Features


DC voltage/current sourcing in 10nV/1nA steps

The output voltage normally can be set in four ranges of 0 to ±1199.999 V in the minimum 1 μV steps. When the divider voltage function is selected, it can be set in three ranges of 0 to ±1199.999 mV in the minimum 10 nV steps. This is ideal for the adjustment, test, maintenance and calibration of high-sensitivity devices and elements.

The output current can be set in three ranges of 0 to ±119.9999 mA in 1 nA steps. Both a voltage limit and a current limit can be set for voltage sourcing (except divider voltage) or current sourcing. They can protect against damage caused by an operation mistake.

6166 Output Range

JIS-compliant thermal electromotive force output function

The 6166 has a function to generate thermal electromotive force of thermocouples according to the JIS table. Selecting the type of thermocouple and temperature to be generated will output voltage corresponding to the setting temperature. The type of thermocouple is selectable from eight types: T, J, E, K, S, R, B and N. The JIS standard is JISC1602-1995 or JISC1602-1981. For type N, only JISC1602-1995 is applicable. The reference junction temperature can be set arbitrarily within a range from -270 °C to 120 °C. This function enables temperature calibration of thermometers and other instrumentation systems.

6166 Thermal Electromotive Force Output Function

Smooth polarity switching by bipolar output

As the 6166 employs bipolar output, the source polarity can alternate between negative and positive without switching the internal relays. Consequently, even zero-crossing evaluation is made smoothly in a shorter time. While offering improved operability, the 6166 can be used free from the concern of the mechanical parts lifetime.

Greatly improved operating efficiency by program function

The 6166 has a memory with the capacity of 1,000 data sets for the program function. Voltage, current, thermal electromotive force, temperature, voltage limit and current limit can be stored in this memory.  Any of these data can be output or the data from the first number through the last number can be scanned.

Expanded specifications for system use

6166 Expanded Specifications for System Use

The 6166 is equipped with the GPIB and USB interfaces. The BCD parallel interface that is installed on the former model 6161 is also available optionally.
In addition to the TRIGGER IN signal input for starting the output voltage or current saved in the program memory, the INTERLOCK signal input for controlling the output status by a foot switch, etc. is newly added in consideration of voltage sourcing up to 1200 V, thereby securing easily the safety control.

To give flexibility to the output lines incorporated in a system, the rear output terminals are also mounted. For external control, the remote commands of the former model 6161 are available by using the compatible mode. The 6166 can be replaced with a minimum modification of an existing system.
