TERA Ohmmeter TOM 600

Item Number: 866.600.1

The TERA - Ohm Meter TOM 600 works with the current-voltage measuring process.

To the adaptation to international norms (IEC) EN, DIN, VDE i.e.) you can select the measuring
time with an internal timer.
The measuring voltage can be selected automatically or manually.

An internal EEPROM memory can save up to 99 measured values.
With an Excel software you can read out and control the TOM 600.
