Indication
| Display: | - High-resolution graphic display with backlight - 4-button operation - Freely configurable display modes - continuously rotatable by ± 170 (detent every 90°) - Optional: Remote display and control unit, can be used up to 10 m away from measuring point |
| Configuration memory | - All parameterisation data can be copied from the devices into the configuration memory in the display module. The data is permanently stored there. - The parameters can be transferred simply and quickly to other devices. - The data continues to be stored even in the event of power failure. |
