1007 DC mV Potentiometer/Source Data Sheet - 1

Time Electronics 1007 DC Millivolt Potentiometer and Calibrator Description The 1007 is a versatile portable 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. • Removable protective cover Safety Terminals: Fitted as standard and fully compatible with 4 mm shrouded plugs, as well as standard plugs, bare wires, and spade terminals. • 3 ranges up to 1 V • Accuracy 0.02 % • Best resolution 1 μV • Short circuit and overload protected • LED null measuring facility • Powered by 6 x AA batteries • 100 hours typical battery life • Optional carry case Added Protection: The 1007 comes fitted with an ergonomic rubber cover providing increased protection and durability. It has a textured grip for comfortable handling and openings at the top and bottom to allow access to the battery indicator and a position to place labels if required. It is easy to remove if the user prefers a stand-alone unit or to house the 1007 in the optional 9027 carry case. 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.
