Being a true electrostatic voltmeter, not a field meter means that it reads actual voltage, without confusing it with electrostatic field strength, which is quite different.

It easily measures voltages on devices and subassemblies that cause Charge Device Model (CDM) and Charged Board (CBE) ESD events.

The ceramic tips are used to measure voltage on ESDS devices and subassemblies where discharge and production of transmitted EMI and RFI are major concerns.

Metal tips are used to measure machine tools, production aids, chairs, carts and other objects in the static sensitive environment. The ceramic tips are quite strong but brittle and are used only for ESDS devices, while the plated metal tips are very robust and are used to measure non-ESD sensitive tools and equipment, and to perform routine audit measurements.

- Connect the probe assembly to the CVM-780 with supplied cable
- Ground the unit
- Slide the Power switch to the ON position
- Contact the probe tip to the front panel ground plate to adjust display to zero
- Measure object by touching it with the probe tip

The CVM-780 is a must have for the serious ESD Control Team. One can measure electrostatic voltage at virtually any point in the manufacturing process without discharge, without RFI, without device damage.
Portable, easy to use and accurate, the CVM-780 is designed by leading ESD professionals for ESD analysis professionals and practitioners.
