SB800/SB800U Ultrasonic Test Unit Operating Guide and Technical Information Please read this documentation before operating the SB800/SB800U Model No: SB800/SB800U Display Unit Serial No: Transmitter Probe Serial No: Receiver Probe Serial No: Quality Assurance Completed: Manual code: SB800INST3.1 Manual date: October 2014 Copyright© 2014 Woodsonix Limited 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. Figure 5. Probes and display unit opened for battery replacement 7. Care of the Unit The SB800 is a sensitive piece of test equ…
