Introduction
The T24-HA is an advanced handheld with the ability to
display data display from up to 12 sensors/acquisition
modules. The handheld will display data from any of
Mantracourt’s acquisition modules (strain, voltage or
current).

The wide temperature operating range and the robust technology
ensures that the module it is not susceptible to harsh physical or
electrical environments. The module can operate in two modes:

The handheld has an auto 'off' function which can ‘power off’
acquisition modules to extend battery life and reduce
maintenance costs. The handheld will also power itself 'off'
and acquisition modules if no buttoms are pressed in a
specified period of time.

Result Mode:
This default mode creates a single result by summing the values
from up to 12 acquisition modules simultaneously as well as
allowing users to view the discrete values that make up the result.
Item Mode:
In this mode each acquisition module is treated as a separate
entity and the T24-HA is used to cycle through all available items.
