| Automatic Multipoint Testing of High Voltages |
|
- Maximum of 32 Channels
In single mode, an individual 3930 can measure eight channels, and up to four units can be connected together for a total of 32 channels.In multi-mode, the 3930 has four high and low channels, respectively;and when four units are connected, up to 16 high and low channels can be tested.
- Safe Design
The 3930 can handle up to 5kV of direct current or alternating current.
- The 3930 is a general-purpose high voltage scanner that can not only be controlled
by using the HIOKI 3153's program function, but also by general-purpose logic and sequencers.
