Digital meter for a wide range of tasks

The Universal Power Meter is a digital measuring instrument for a very broad field of application. It features a 6-digit 7-segment display and an RS 232 interface.

Power is supplied by an integrated mains unit. In the event of power loss, measured values are retained in a non-volatile memory.

Single-phase and three-phase measurements

The instrument is designed for both single-phase and three-phase networks. For single-phase measurements in a three-phase system with symmetrical load, a fixed phase factor of 3.0 can be activated for power and energy calculations.

The instrument also records min and max values for W, VA, var, V, A and power factor.

Visualization and logging

Visualization software Type 1091.2-EVDE is available as an accessory. It can display up to four measured values simultaneously in analogue and digital form, show one value as a large-format display and store data for later processing, for example in MS Excel.

The integrated data logger enables long-term measurements and Y/t displays with up to three logger channels.

  • Non-volatile measured-value memory during power interruption
  • Can be used as a demonstration instrument with visualization software Type 1091.2
