The Time Electronics 1007 is a DC millivolt potentiometer and source offering testing versatility for both potentiometric voltage measurement and millivolt source applications. The instrument features adjustable null zero and sensitivity via front panel controls, with maximum sensitivity enabling null balance to resolve 3 microvolts.

The 1007 provides three output ranges up to 1V with 0.02% accuracy. The null meter resolution is 2µV, allowing precise measurements. It delivers 20mA output current and includes short circuit and overload protection for reliable operation in various test scenarios.

The instrument is portable with rechargeable batteries and includes a carrying case. Battery life is approximately 100 hours typical with 6 AA batteries. Applications include thermocouple simulation, calibration of chart recorders, data loggers, and other millivolt-input devices.

Safety terminals are compatible with 4mm shrouded plugs, standard plugs, bare wires, and spade terminals. The 1007 is suitable for laboratory, field, and industrial use where accurate millivolt sources are required.
