The 1007 DC Millivolt Potentiometer and Source can be used for potentiometric voltage measurement in addition to its operation as a millivolt source. The null zero and sensitivity are adjustable via front panel controls - maximum sensitivity enables null balance to resolve 3 microvolt.

The 1007 is one of Time Electronics' comprehensive portable testing equipment range, and is particularly useful for themocouple calibration and thermocouple simulation. Accurate voltages equivalent to the output from a thermocouple can easily be set on a 1007, enabling fast calibration of temperature measuring equipment. Alternatively, the 1007 can measure thermocouples output by operating as a potentiometer.
