7. How to Calibrate the Load Measuring
Leaving the pre-adjusted menu-item unchanged means that the loads
are to be entered in terms of percent of the nominal load, such as for example
100% for full load and 105% for overload.
Take the following steps to calibrate the WeightWatcher Beam
1. Mount the rope-sensor to the upper belt
2. Connect WeightWatcher Beam to a power supply ranging between 12V and
28V DC Calibrate the WeightWatcher Beam both under full load and zero-load
conditions
a. How to Calibrate Zero Load
Purpose of this function is to compensate the weight of the empty
cabin. Take the following steps:
i. By navigate to menu-item and select it by pressing
. Then navigate by to menu-item and select it
by pressing . The standard value (refer to ) is
(0% load, i.e. empty cabin). As soon as you will have adjusted
the last digit, the whole figure will be flashing.
ii. Apply it by pressing . After that a countdown will be running
from to . At the current weight of the car
will be measured. It goes without saying that at that moment
there must not be anything in the cabin or on the car roof that
does not belong there under normal operation conditions (tools!),
and that there must not stay any person in the cabin or on the
car roof in order not to warp the zero load parameter.
b. How to Adjust Full load
Take the following steps:
i. By navigate to menu-item and select it by pressing
. Then navigate by to menu-item and select it
by pressing . After that adjust on the display an arbitrary load
to be loaded into the cabin. Unless you changed the standard of
menu-item enter this load in terms of a percentage of the
nominal load, i.e. 100% (), if you are loading the nominal
load, or 75% () if you are going to load ¾ of the nominal
