software
Graph ESM-100 software: After connecting ESM-100 to a computer, remote control can be achieved through Graph ESM-100 software, and all measurement results can be recorded. This software is specially designed for ESM-100 and meets EMC monitoring requirements. With just a click of the mouse, you can draw, table, and create three-dimensional spatial distribution maps. The scale and corresponding axial letters are automatically generated. Simply select the corresponding control key to directly track the measured value or display the real-time measurement range curve.
Software Features
lVisual display of measurement value chart, real-time measurement curve online display, simple operation, intuitive desktop table display, each measurement value with annotation space for setting limits
lESM-100 memory block download burst control record
lSnapshot function
lMagnetic field workload correction ESM-100 remote control can output graphics and forms with perfect help function
lCompatible with Windows operating system
