initiated by either the Manual or Automatic Hold operations.
The Manual Hold operation is triggered by pressing the HOLD button. Once the
Manual Hold operation has been initiated, an average weight is calculated over a
period of time determined by the Manual Hold Period parameter. Once
calculated, the averaged weight will be shown on the display. At this point it can
be saved or discarded. When saved, it can also be directed to a serial port for
output to a computer or printer.
Note: There is also an Automatic Hold feature available
Note: The Manual Hold feature trigger can be disabled with the Hold Button
parameter in the Auto Hold menu.
1. From the Normal Operating mode
and with an active load on the
scale, press the HOLD key.

2.5 Auto-Hold Stable Weight Detection
The 300 Series can store Weight Records and the record storage process is
initiated by either the Manual or Auto-Hold operations. The Auto-Hold feature is
controlled by a number of parameters in the Auto-Hold menu.
The Auto-Hold operation is triggered when a measured weight is in range. Once a
sufficient number weight readings have been collected and a valid average has
been calculated, the averaged weight will be locked on the display. If sufficient
change in the weight occurs, the lock will be released and the 300 Series will
attempt to reacquire a valid average and lock condition. A locked weight can be
saved. When saved, it can also be directed to a serial port for output to a
computer or printer.
Note: There is also an Manual Hold feature available
Note: The Auto-Hold feature trigger can be disabled with the Activate parameter
in the Auto Hold menu.
1. From the Normal Operating
mode, when an in-range load is
placed on the scale, the Auto-

valid average has been calculated,
the averaged weight is locked on
the display and the HOLD status
indicator flashes rapidly.
Sufficient activity on the scale (or
the EXIT key) can cause the lock
to be released.
