Description of system
The ALRS2 load cell is a multi-range system that gives you six units of measurement:
Te
KGS
LB
KN
(UST) US Tons
mV/V
With a telemetry working range of a minimum of 700 meters over 360°, this will give you peace of
mind knowing that you will never lose signal.
The system has a constant peak mode that is displayed on the handset, the displayed peak can also
be zeroed, and a power saving mode which is a battery saving option.
With the safety feature of an audible and visual overload alarm gives you complete control over your
lifts.
The load cell is turned on via a switch on the load link and the monitoring system is switched on via
the power button on the ALRS2 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 ALRS2 handset.
Note: The load cell referred to in this instruction manual refers to any load monitoring device that
the ALRS2 electronics are calibrated to. This includes, but is not limited to, load link, load
shackle and compression load cell.
