  • Page 3: Introduction

    The charger/battery system is designed for long, safe battery life, the charger will not over charge and the unit will re-set if a high current operation is call with low batteries. We highly recommend users to watch instruction videos, visit www.momento.se Page: 2 / 32...
  • Page 4 The Δσ pulse-echo ultrasonic time-of-flight measurement device; measures, displays, stores and transfers bolt load data. The Delta Sigma uses a sealed colour touch screen for all operator I/O. All data is entered and presented on a 4.3” colour, resistive touch screen. Data and digital signal traces are stored for later display and transfer.
