5 Operation
There are no user controls on the actual uDL1. Data acquisition cannot be scheduled to start at a particular date and
time. Instead, the device automatically powers up when the measurement cable is installed and immediately starts data
acquisition activities. The device ceases data acquisition and powers down when the measurement cable is removed.
The waterproof connector that mates to the uDL1 has an automatic physical locking function. The white arrow on the
cable should align with the black arrow on the top graphic overlay of the uDL1. When the cable is inserted it will "click"
to indicate that the connector is locked in place. The cable is released by pulling back the black ring (which has the white
arrow) of the connector.
The measurement cable has two banana plugs to allow connection directly to banana jacks. There are also two extension
clip wires included that can attach to the banana plugs of the measurement cable.
The bottom of the uDL1 includes a magnet which allows the device to be attached to ferrous surfaces. There are also
two holes in the base of the device that allow the device to be secured to a string or structural wire in applications where
it is dropped down a tube such as test point stations. In GPS equipped models the GPS antenna is located on the end
opposite the uDL1 connector. Even though the GPS antenna in the uDL1 is reasonably omni-directional, best GPS signal
reception will generally occur when the GPS antenna system is pointed upwards towards the sky.
The label on the bottom of the uDL1 identifies the type of unit, the hardware generation, the factory options and the unit
serial number.
