Used OHMITE 3430A #9293094 for sale

OHMITE 3430A is a high precision electronic test equipment that is commonly used throughout electronics manufacturing, testing, and servicing industries. It measures the electrical resistance of materials, devices, and components and is capable of giving accurate and repeatable results with high levels of accuracy. The instrument is a highly reliable and versatile piece of test equipment that can be used to measure extremely small resistance values and also measure high resistance values up to 10 MegaOhms. 3430A is a solid-state design utilizing a solid-state gold palladium alloy sensor element, allowing for both long life and excellent accuracy. The gold palladium alloy sensor element is connected to a bridge circuit, which provides an extremely high-resolution reading of resistance. The bridge circuit utilizes two fixed resistors and two variable resistors, which can be adjusted to set the range and resolution of the measurements taken. The HOMITE OHMITE 3430A features a robust user interface, providing three modes of operation. It has a manual mode, which requires simple direct connection of the leads to the device and adjusting the range and resolution manually. It also features a calibrate mode, which enables the user to input a reference resistance value and allows the instrument to perform an automatic calibration against the reference. Finally, it has an auto mode which allows the user to specify a desired range and resolution, and the instrument will automatically adjust the variable resistors to achieve this. 3430A also features a wide range of safety features, including an overload protection circuit, which prevents damage to the device due to over-current. It also has a high voltage protection circuit, which prevents arcing and sparking and possible damage from high voltage. Additionally, it has an open connection protection circuit, which prevents a short circuit if the leads are connected to an open circuit. Overall, OHMITE 3430A is an extremely reliable, accurate, and versatile piece of test equipment. It is easy to use, requires only basic setup, and provides repeatable and highly accurate resistance measurements. With its wide range of safety features, 3430A is well-suited for use in any electronics laboratory environment, while its user interface and three operation modes make it an excellent choice for use with automatic test equipment.
