SB800/SB800U
Ultrasonic Test Unit
Please check your package contents include:
Operating Guide and Technical Information manual.
Carry case containing transmitter probe, receiver probe and display unit.

1. Overview
The SB800 is an ultrasonic test unit for use in making single pulse transmission
time measurements in solid samples. The SB800 consists of three units:
A transmitter probe (Red)
A receiver probe (Blue)
A display module (Silver) where readings are given in microseconds (μS)
The unit operates by the transmitter probe producing an acoustic pulse at the tip
of the probe and timing the subsequent interval until the pulse is successfully
detected at the receiver probe. The transmission time will depend on the
propagation within the sample and the thickness of the sample.
The three units are switched on automatically when they are removed from the
carry case. Note that the carry case contains magnetic material that may damage
sensitive items, such as credit card strips, that are held in close proximity.
2. High-Voltage Warning!
The transmitter probe has a high voltage present internally. This can cause a
painful electric shock, and for this reason we recommend that you return faulty
units to Woodsonix or its authorized dealers for servicing.
The unit should not be operated with the probes immersed in any liquid.
3. Intellectual Property
All intellectual property relating to the concept, design and implementation of the
SB800 hardware and software belongs to Woodsonix Limited. Copyright, patent,
and other infringements will be dealt with aggressively.
4. Operating Instructions
The units are switched on automatically by removing them from their carry case.
In order to prolong battery life, the units should be turned off (by replacing the
base unit and probes in the case) whenever they are not in use.
4.1 Unit Identification
The probes are colour coded. The transmitter probe has a red coloured body and
the receiver probe is blue. Readings are shown on the display unit's screen. A
sample screenshot is shown in figure 1.
Figure 1. Display-unit screenshot
4.2 Displayed Measurement
With the probe tips firmly applied to a solid sample, a reading of the transmission
time in microseconds should be displayed. If no measurement is displayed this
can indicate that the attenuation in the sample is too great, the transmission time is
greater than 2000 microseconds, or the unit is faulty (check batteries). Figure 2
shows the display location of the reading.
Figure 2. Reading portion of the display
With the display unit turned on and the probes held apart, the screen should
show: ‘----’ instead of a reading, indicating that no measurement is being made.
If the display shows a reading in this situation this may indicate a faulty/damaged
probe or low battery voltage.

4.3 Previous Reading
The number in the top right of the display-module screen represents the most
recent good reading. Its display position is shown in figure 3.
Figure 3. Previous reading portion of the display
4.4 Battery-Level Indicators
There are three battery-level indicators on the right of the display-module screen
as shown in figure 4. See section 6 for more section for more information on
battery replacement.
Figure 4. Battery life indicator portion of the display
The unit is carefully calibrated after manufacture, and is rechecked during the
quality assurance stage. In order to test this calibration, and the correct operation
of the unit, press the two probe tips together; a reading of ‘0’ should be displayed.
5. Serial Number Identification
Each SB800 component is uniquely identified with a serial number. In addition to
a physical number, an electronic serial number is stored in each component and
these are shown on the screen when the display module is turned on. Note that
the displayed probe serial numbers are those in use when the display unit was
turned off. Therefore, the first time replacement probes are used, the displayed
serial numbers will not match the actual probes.
6. Battery Replacement
Each battery indicator is shown as a solid rectangle when the batteries are fully
charged. An empty, or near empty, rectangle indicates that the batteries in the
associated unit should be changed. The letter beside each battery tells which unit
the battery reading is for:
R (Red) for the transmitter probe
B (Blue) for the receiver probe
S (Silver) for the display module
The unit will continue to give accurate timing measurements when the battery
voltage is low, as long as the transmit pulses continue, but the sensitivity will be
reduced. Ensure that the batteries are inserted correctly and never mix old
batteries with new ones. For maximum battery life, alkaline batteries should be
used.
6.1 Replacement of Probe Batteries
Unscrew the cap at the rear of the probe by turning it anticlockwise. The battery
holder can be slid out and the batteries changed. Ensure that the terminals on the
end of the battery holder point towards the probe tip when it is re-inserted, and
that they line up the metal contacts in the probe. Figure 5 shows the probes with
unscrewed caps.
6.2 Replacement of Display-Unit Batteries
Remove the four screws on the rear of the display unit to open up the battery
cavity. Replace the batteries in the battery holder. Do not remove the plate that
covers the front of the display unit, as it seals the electronic and microprocessor
components from environmental damage. Figure 5 shows the display unit with
the battery cavity visible.

7. Care of the Unit
The SB800 is a sensitive piece of test equipment and should be treated with care.
Exposure to heat, moisture and dust should be avoided. If moisture is allowed to
enter the display unit or probes, the batteries should be removed and the units
thoroughly dried before reuse. The probe tips are especially sensitive to physical
shock. Do not tap or bang the probe tips sharply, as the internal transducer
ceramic is inherently brittle and may shatter. We recommend returning the unit
for service and calibration every year.
8. Probe Operating Range
The probes are designed to work reliably up to 5 metres from the display unit.
Depending on environmental conditions, the necessary sensitivity of the display
unit's radio receiver may cause it to pick up signals from probes up to 200 metres
away. This should be taken into consideration when simultaneous use is planned
for two SB800 units in the same vicinity.
9. Regulatory Conformance
The SB800 unit complies with AS/NZS 4268. It is approved for operation within
Australia and New Zealand.
The SB800U unit complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
