Available functions
The ALRS load cell is a multi-range system that gives you four units of measurement in
(Te/Kg/Lbs/US TN). The system has a peak mode and an auto on/off function which is a
battery saving option.
We can guarantee you a telemetry working range of a minimum of 300 metres over
360°, this will give you peace of mind knowing that you will never lose signal.
The load cell is turned on via a switch on the load link and the monitoring system is
switched on via the on button on the ALRS handset. This is to save battery during long
term out of use. The load cell can be left switched on and can then be switched on/off
from the ALRS handset but it will stay in standby mode using battery.
The ALRS also has a data logging feature so when needed your load cell can do so much
more for you.
The ALRS system also has a peak hold function so you can monitor your peak load.
You can check the battery system on both the handset and load cell at any time.
