The same TTR test circuitry from Megger that is in the existing TTR300, TTR310 and TTR330 can be found in the latest model. The primary differences between the units in the range are user–interface related and data storage capability.

Primary features of the TTR320:

  • Display: 5.7 in. color, icon based
  • Data Storage: USB flash drive; >100,000 files
  • Data Transfer to PC: USB flash drive
  • Print: 4 in. strip via serial

The four products in this series span from the top–end model (TTR330) to the remote controlled "black box" TTR300.
