1007 DC mV Potentiometer and Calibrator

The 1007 is a handheld calibrator that 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.

Three output ranges are provided to give adjustable output values from 1 μV to 1 V with a basic 0.02 % accuracy. For signal injection, the operator needs to switch on, check the battery condition, select the range, and set the required voltage using the thumbwheel switches. The 1007 uses a precision reference diode and low temperature coefficient resistors to give a highly stable output.

Power is provided by 6 AA batteries. Battery life is several months, depending on usage. The battery condition is monitored by an indicator situated on the top of the unit. The 1007 has up to 20 mA drive current and is short circuit and overload protected. An off/normal/reverse output polarity switch is provided.

  • Accuracy 0.02 %
  • 20 mA output current
  • Short circuit and overload protection
  • LED null measuring facility
  • 100 hours typical battery life
  • Portable with protective rubber cover
1007 Safety Terminals

Safety Terminals

The instrument connections are via safety terminals that are compatible with 4 mm shrouded plugs, standard plugs, bare wires, and spade terminals.

These terminals are specifically designed with safety features including limited opening distance and a raised flange around the metal connection surface. This ensures that the clearances are sufficient to make the exposed metal parts touch-proof.

1007 Protective Boot

Added Protection

The 1007 DC mV potentiometer/source comes fitted with an ergonomic rubber cover providing increased protection and durability. It has a textured grip for comfortable handling and a top opening for access to the battery level indicator and cell compartments.

It is easy to remove if the user prefers a stand-alone unit or to house the instrument in the optional 9027 carry case.

1007 Applications

Suitable for calibration and simulation of thermocouples. Accurate voltages equivalent to the output from a thermocouple can be set quickly and easily on the 1007, enabling fast calibration of temperature measuring equipment.

Alternatively, the 1007 can measure thermocouples output by operating as a potentiometer. Other applications include chart recorder calibration, A/D converter and multimeter calibration, and use as a stable voltage for backing off DC offsets.
