- Data transfer to PC through serial link
- Capability to drive automatic multi-electrode switching system (E-NODE & MULTINODE)
EASE OF USE
Taking a reading is very easy:
- Strike SPACING to input spacings (AB/2, MN/2)
- Select output voltage (50V to 400V)
- Strike START
- V and I are displayed during stacking
- Strike RESULT to read Rho
- Strike MEMORY for data storage
ACCURACY
