The NSRTW_mk2 is always on. However, when not in operation it only measures time, which only takes a tiny operating current. In that Idle state it can stay on for up to 6 months. When the NSRTW_mk2 is actively measuring, its power consumption allows it to record for 1 week.

 

The NSRTW_mk2 can be configured to connect to a server at regular intervals. When that function is enabled, the NSRTW_mk2 will activate its WiFi™interface at the defined interval, and attempt to connect via WiFi™for up to 1 minute. During that time, the instrument’s power consumption will be increased. If the connection fails the NSRTW_mk2 will fall back to its previous state (Sleep or Recording).

 

Note: WiFi™ communications consume battery, so when leaving the NSRTW_mk2 unused for a long time, it is important to disable the WiFi™periodic connection feature.

 

In applications where the NSRTW_mk2 must record for longer periods of time, it can be connected to a USB charger. For outdoor-use, a USB-output solar panel, such as the one found in https://convergenceinstruments.com/product/data-logger-accessories-solar-pannel/ is an ideal solution that will power the instrument indefinitely.
