F340A is a digital indicator for strain gauge type sensors that measure pressure, load and torque. It is best used in the Pass/Fail acceptance judgment performed by automated devices and testers. F340A is a practical device equipped with compact DIN 96 square size, peak/sample hold function, and the equivalent input calibration function which allows calibration by simply key-inputting the rated value of the sensor without applying an actual load. This digital indicator has been made affordable while including all of these convenient functions at the same time.
