No, the room lighting is not sufficient for this. The light-sensitive sensor is set so that the second display line is only activated by a strong light source, such as direct illumination with a standard torch.

The current power, marked with a "P", is only displayed permanently if the PIN is or has been deactivated. If you have activated the PIN, your saved consumption data will be displayed in the second line after flashing a light on the optical button. You will find further information on this in the operating instructions, starting on page 12.

With a special meter type by the manufacturer Iskra (eHZ-MS2020, type MT691-D4A52-K0y-H01), the current power is not permanently shown in the second line of the display if the PIN is deactivated. Please flash a light briefly on the optical button of this meter, and the current power will then be displayed in the second line of the display for 120 seconds.

After entering the PIN, you can activate or deactivate the optical information interface under "InF" in the display sequence. The information interface is activated when "InF on" is displayed and deactivated when "InF OFF" is displayed.

If the information interface has been activated, data can be read and further utilised via an optical scanner and a computer with the appropriate software. As an optical scanner also covers the optical button, it is not possible to input via the optical button.

Activating the optical information interface has no effect on the data shown in the display.

If you flash on the optical button again, a display text will appear, and you can then jump through the display sequence for the second display line by pressing it again. Please refer to the operating instructions starting on page 12 for the display sequence when the PIN is activated.

If the PIN is deactivated, you can enter the PIN in the second step after flashing on the optical button and the display test.

No. If you have a smart meter system, only the menu items "InF" and “PIn" are displayed on the basic meter.
