5.4 Test Block
A test block is included with the PUB equipment to allow the
transducers and inter-connecting cables to be functionally
checked.

2. Select Quick start and enter the parameters shown in
the table below for the appropriate transducer type (A or B):
3. When the above data is entered, the SENSOR SEPARATION screen will be displayed.
4. Press either the UP/DOWN cursor keys to go to the SENSOR SELECTION menu.
Sensors: INVALID Interpretation: The selected temperature is higher than the maximum allowed for the
sensor type.
Response: Enter a different temperature.
Mode: Err Typ Interpretation: The selected sensors are invalid and the mode cannot be verified.
Response: Select a mode that gives a non-zero separation distance.
BATTERY ERRORS
Battery Low Interpretation: The battery has discharged to below 30% remaining. This leaves the
instrument with approximately 4 hours remaining, depending on power usage, before it
needs recharging.
Response: Recharge the internal battery at the earliest opportunity. Do not leave the
instrument for a prolonged period with a fully discharged battery.
Battery Exhausted Interpretation: The battery is approaching a fully discharged state and the instrument is
about to store the internal data and shut-down.
Response: Recharge the battery.
