1. Overview
4. Operating Instructions
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.
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.

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.
