Abstract: An energy consumption meter includes a first input for providing a first input signal derived from a voltage, a first analog-to-digital (A/D) converter electrically connected to the first input to generate a first output signal based on the first input signal, a second input for providing a second input signal derived from a current, a second A/D converter electrically connected to the second input to generate a second output signal based on the second input signal, a multiplier to combine signals corresponding to the first and second output signals, and a phase evaluation block having two inputs that are electrically connected to the first input and to the second input. The phase evaluation block measures a phase difference that corresponds to a phase difference between the first input signal and the second input signal. A phase correction block corrects for the phase difference in one of the first output signal and the second output signal.

An exposer has an exposure drum for holding the printing plate, and has a cylinder. An internal pipe and webs connect the cylinder to the internal pipe. Using a rotary lead-through, a temperature-control liquid is led into the internal tube of the exposure drum and, by thermal conduction via the webs and the cylinder, keeps the printing plate at a constant temperature.

Abstract: An energy consumption meter arrangement is specified which has two inputs (1, 2), to which signals are fed which are dependent on an electrical voltage (V) and an electrical current (I). These signals are digitized in analog-to-digital converters (3, 4) and combined with one another. In order to correct phase differences which may be caused by means for coupling-in the signals (12, 14), a phase evaluation block (9) is coupled to the inputs (1, 2) of the energy consumption meter arrangement. The phase evaluation block (9) drives a phase correction block (6) at the output of an analog-to-digital converter (4). As a result, cost-effective compensation of phase errors is possible with little complexity, which makes DC isolation possible at the input whilst avoiding measurement errors. The described energy consumption meter arrangement is particularly suitable for implementation using integrated circuit technology.
