Using the device display (optional)

A 4-line liquid crystal display (LCD) is used. The local display shows measured values, fault
messages and notice messages.
The display can be removed for easy operation (see diagram, steps 1 - 3). It is connected to the
device via a 90 mm (3.54 in) long cable.
The device display can be rotated in 90 ° stages (see diagram, steps 4 - 6).
Depending on the orientation of the device, this makes it easy to read the measured values.
