Technical Features

  • The digital ALMEMO® D7 measuring module uses its own integrated AD converter. The overall accuracy of the measurement is independent from the ALMEMO® V7 display unit/data logger. The measurement rate is solely defined by the integrated AD converter. On the ALMEMO® V7 measuring
    instrument all D7 measuring plugs work in parallel at their own measuring rate.
  • Dynamic measuring signals are measured by the ALMEMO® D7 measuring module at a fast conversion rate.
  • The ALMEMO® V7 measuring instrument saves the measured values, and the measuring software WinControl will display them graphically.
  • The maximum, minimum, and average values can be calculated by measuring functions in the measuring device or in the measuring software.
  • The measuring input is overvoltage proof and galvanically isolated from the ALMEMO® V7 measuring device.

Applications

  • Inexpensive monitoring of several DC voltage signals with a large number of measuring modules.
  • Monitoring the charge and discharge processes (current, voltage, power) during the development of rechargeable batteries/ batteries for electromobility and for other battery-operated devices.
  • Monitoring the supply voltage and the current consumption during switch-on and switch-off processes of DC motors and other consumers.
  • Checking switches and circuit breakers using fast switching cycles.
  • Measuring the response time of electronic switches.
  • Calculating the power by simultaneously measuring voltage and current in one measuring module.
  • Monitoring the electrical parameters voltage, current and power of photovoltaic modules and photovoltaic systems while environmental parameters such as temperature, global radiation, and other meteorological parameters are recorded at the same time.
  • Measuring fast changes in power during load tests with rapid load changes.
