3 Product
The ALMEMO® WLAN module is used to establish a wireless connection between
the ALMEMO® measuring device and a PC and one or more ALMEMO® measuring
devices. In doing so, the connection can be established either via the local WLAN
network of the ALMEMO® WLAN module (use as access point) or via an external
WLAN network (e.g. company network) (use as client).
The connection to a PC, tablet or smartphone can be used to configure the
ALMEMO® measuring device or to read out measured values during or after a
measurement.
Examples for networking with the ALMEMO® WLAN module
