The 1007 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 particularly useful for calibration and simulation of thermocouples. 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. Power is provided by 6 AA (penlight size) batteries. Battery life is several months, depending on usage. The battery condition is monitored by an indicator, which is mounted on the end of the unit. Unit comes supplied with dry cell batteries and sturdy carry case. The source version without null measuring facility is also available from Time Electronics (1006 DC Millivolt Source).
