General
The FTS Axiom H1 Datalogger is a robust weatherproof Datalogger with a built-in power management
system, support for a variety of sensors and telemetry devices, an industrial grade colour touchscreen
display, and standard USB ports.
The Axiom H1 employs the FTS Quick Touch System™ which combines a graphical user interface (GUI)
with a colour touchscreen display and USB ports for easy operation. On-site data retrieval, Datalogger
parameter optimization, and performance information are simple and intuitive.
The Datalogger can store multiple Datalogger configurations as well as several years of typical
environmental data. Data in the Axiom H1 is stored in a circular buffer in non-volatile memory with
time tags on each record. The time tags have a resolution of one second and correctly account for leap
years. Non-volatile memory ensures that data is preserved through power cycles and the circular buffer
ensures that the oldest data is overwritten by the newest data when the memory fills.
The Datalogger is watertight, even without connectors attached. Device connectors (sensors and
telemetry) are circular metal shell, bayonet, military style connectors which are uniquely keyed and
colour coded to minimize erroneous connections. The Datalogger supports SDI-12 sensors as well as an
FTS Rain Gauge.
Some models have a built-in power management system which integrates a SOLAR PANEL input and a
BATTERY input to provide a method of regulating and maintaining the optimal battery charge
condition.
Support for two independent telemetry devices is standard with each Datalogger. The Axiom H1
Datalogger can be ordered with two external telemetry ports or with an internal FTS G6 transmitter with
one external telemetry port. See Figure 1 for the available configurations. The Axiom H1 automatically
synchronizes with UTC time if an FTS G6 transmitter is connected either externally or internally to the
Datalogger. The Datalogger can be set to any time zone offset.
