The 1007 DC Millivolt Potentiometer and Calibrator is ideally designed to provide an excellent quality performance and functionality for very specific purposes. It is a precise, cost-effective type of device which is ideal for potentiometric voltage measurement applications. It is integrated with 3 output ranges to provide several output values from 1µV to 1V with a basic 0.02% accuracy. The user is highly advised to turn the switch on, check the battery condition of the device, choose the range, and set the required voltage using the thumb wheel switches incorporated in the system. The 1007 DC Millivolt Potentiometer and Calibrator uses an accurate resistor to be able to provide a highly stable or fixed output on the superior quality apparatus or device. It is also built with 6 AA batteries to ensure a well-powered up system.
