Key facts

  • 6½ digit calibration working standard
  • ±10 nV to ±1200V / ±1 nA to ±120 mA
  • High-precision bipolar DC voltage/current source
  • High accuracy: ±35 ppm/year (±25 ppm/90days); ±5 ppm/24hrs
  • JIS-compliant thermal electromotive force output function

High-precision DC voltage/current calibration source

The 6166 is a highly accurate, highly stable bipolar calibration source with voltage settings from 10 nV to 1200 V and current settings from 1 nA to 120 mA. Due to its outstanding accuracy and stability, it is ideal for calibrating high-precision digital voltmeters and other instrumentation systems or sensors.

Features & benefits

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

High resolution and voltage supply up to ±1200 V

The output voltage can normally be set in four ranges from 0 to ±1199.999 V in minimum 1 μV steps. When the divider voltage function is selected, the voltage can be set in three ranges from 0 to ±1199.999 mV in minimum 10 nV steps. This is ideal for adjusting, testing, servicing and calibrating high-sensitivity devices and elements. The output current can be set in three ranges from 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) and current sourcing. They can protect against damage caused by an operating mistake.

Output characteristics

JIS-compliant thermal EMF output function

Optimal for temperature calibration of thermometers/sensors

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. 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.

Support of different thermocouple modes

Smooth polarity switching with bipolar output

Continuous zero-crossing

Since the 6166 features a bipolar output, the source polarity can alternate between negative and positive without switching the internal relays. This streamlines zero-crossing evaluation. The 6166 not only offers improved operability, it is also free of concerns about the mechanical parts lifetime.

Smooth polarity switching by activating bipolar output mode

Comfortable program function

1000 data set memory for automatic test runs

The 6166 has a memory  capacity of 1000 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 this data can be output or the data from the first number to the last number can be scanned. This function makes it easy to build a simplified auto test system and greatly improves the operating efficiency.

Memory scan operation

Easy system integration

USB and GPIB interfaces as well as trigger and interlock inputs

The 6166 is equipped with GPIB and USB interfaces. The BCD parallel interface installed on the former 6161 model 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 with a foot switch, etc. has been added in consideration of voltage sourcing up to 1200 V for easy and secure safety control.
