Certificates 3.1 Class Type Approval According to IACS UR‐Z17, the ultrasonic tightness testing equipment used by Class Service Suppliers for testing the weathertight integrity of hatch covers should be class type approved. Like its predecessor – the SDT Sherlog TA – both the Sherlog Kit Cadet (with SDT200 receiver) and Sherlog Kit Master (with SDT270 receiver) have been developed in order to meet with Class criteria for Type Approval. Both equipments have the necessary features on board to comply with, and exceed, Class type approval requirements. The high quality of SDT equipment reassures ship owners and their managers that their ships have been inspected with state of the art equipment that meets with the highest industry standards. 3.2 The calibration certificate SDT recommends annual recalibration of SDT instruments and sensors. This periodicity is coherent with the observed long‐term stability of SDT electronic equipment’s. However The first SDT certificate is valid for a period of 15 months (to avoid penalizing a customer receiving an instrument that stayed in stock for 3 months). SDT recognizes that each customer may have their own Quality Assurance Standards and internal requirements. If a customer has established a Quality Assurance Program that includes a documented procedure for measurement deviations, and if an instrument and the relevant sensor show acceptable deviations and do not show signs of physical damage, then calibration periodicity could be extended to two years. Third party organizations having more authority (Class, or State Administrations) may have defined their own regulations for example 6 months, or 2 years calibration interval: by evidence, local legally applicable regulations supersede SDT rules. For these reasons, SDT Calibration Certificates do no more mention a “calibration due date”, but simply the “last ...
Ultrasonic waves are sound waves beyond the range of human hearing (>20 kHz). To be detected, we need to use an instrument like the SDT270, with the capability to receive ultrasonic frequencies and convert them to corresponding audible sounds. Ultrasonic waves travel through gases (air), liquids (water, fuel) and solids (bearing housings) in a very directional nature; unlike audible sounds which disperse in all directions. Ultrasounds are low energy sound waves, therefore they are quickly absorbed by the medium through which they travel. Ultrasonic waves are generated by: Naturally occurring mechanical phenomena (friction of rotating equipment), pressure or vacuum leaks (pneumatic, gas, steam) or arcing and corona (electrical problems). Artificially by means of a transmitter (like the SDT 200 mW or the SDT 8 MS ‐ 8 x 125 mW) for tightness testing. 4.1.2 Applying ultrasonic waves on the Sherlog The SDT270 detects ultrasonic signals, converts them to audible frequencies, and amplifies them. The challenge is to transpose the received signal, using the heterodyne technology, into an interpretable audible signal. This solution extends the ability of the human ear beyond the simple audible range and into the ultrasonic one. ...

Due to logarithmic characteristics, each and every time the A l evel is increased (decreased) by 10 (next or previous step), the gain is multiplied (divided) by approximately 3. For example: A = 40 ‐> Gain = 100. A = 50 ‐> Gain = 300. Understandably, when the ultrasonic level is high, little amplification is needed. When the ultrasonic level is very low (small leaks), the amplification required will be high. When, in presence of a source of ultrasounds, the SDT270 receiver must be adjusted to an optimal A l evel. The SDT270 receiver assists ...

Like most batteries these days, leaving the SDT270 charging after the charger says it is charged does not hurt the battery – in fact it very slowly tops the charge up a little more. During the charging process, a status led on the charger will be blinking. For more info on the charger status see 17.4 Battery charger. You can charge the SDT270 receiver switched off. You can also trickle charge the SDT270 receiver switched on, so you can be using it to load and unload data, for example, and charge it at the same time. 4.7 The battery autonomy A fully charged battery will give you about 8 hours of continuous use. This will vary of course depending upon your need to use the backlight and the power drain of certain external sensors that you might be using. You can increase the autonomy by more than 20% by disabling the LAN. (see 0 Connecting the device on a computer network) You are also able to set an Auto Power Down and a time before Power Down switching off the backlight.

12 Using the multi‐setting transmitter 12.1 Recommendations The multi‐transmitter must be used: In combination with a SDT270 receiver; Outside any classified zone requiring intrinsic and fireproof safety. Away from discharge of water and must never be immersed. It is important to prevent any foreign bodies entering the ultrasonic transducers, such as grease, dust, etc. Within hygrometric and temperature limits stipulated in the technical characteristics. Note: If necessary, the transmitter can be protected / covered by thin / fine mesh cloth (e.g. nylon stockings) to prevent dust from entering into the transducers when working in a dusty atmosphere. 12.2 Working position When preparing for testing the weathertightness of hatch covers and determining the OHV (Open Hatch Value), the multi‐transmitter should be placed, ideally, in the center of the tank top. The multi‐transmitter covers an operational spherical volume of 20 meters (60 ft) around its position. For larger volumes, the multi‐transmitter should be moved several times; it is then necessary to take a new OHV (Open Hatch Value) measurement after having repositioned the transmitter. The volume covered by one multi‐transmitter. The zone covered by the multi‐transmitter when set to various points. If the hold is not empty, the multi‐transmitter can be placed on top of the cargo. ...
The 8 transducers of the multi‐transmitter work in t h e bi‐sonic mode on frequencies stabilized at 39.2 and 39.6 kHz, with total transmission power also stabilized at 8 x 125 mW. The measurements will be carried out by the SDT270 receiver (see chapter 15 for the use of the equipment). 12.6 Powering Off To power off the transmitter, set the switch to the Off position (1). The red operating status light should switch off. 13 Charging the SDT 8 MS transmitter battery pack The battery packs are charged in our factory for test purposes but the battery packs are discharged before being dispatched, because of international air transport regulations.

Before every recharging operation, unplug the battery charger from the mains and re‐plug it, in order to reset the internal timer. • Connect the plug to the battery’s support socket. • Place the battery in the support ( contacts inside). There is no preferential direction for the battery. ...
14 The multi‐transmitter operational problems 14.1 Ultrasonic transducer Decreasing ultrasonic signal The main reason, when an unstable signal is read/displayed on the SDT270 receiver, is that the battery is not fully charged. The discharge curve of the battery is constant over a long period. Any variation in power will immediate stop the transmitter in order to prevent incorrect measurements. Curve illustrating a decreasing ultrasonic signal. Low but constant level ultrasonic signal If the signal measured from a transducer during the function test (when the Amplification level is set at 10 and the transmitter selector switch position in position 1) is significantly lower than 95 dBµV and however remains constant, this indicates that the functioning of the transducer is impaired by some clogging/damage . In this case, clean the transducer(s) or protective grid . Do not used compressed air to clean/blow out any impurities. Defective transducers Transducers may become damaged due to: • A mechanical shock/impact: return the equipment to your distributor in order to change one or more transducers as necessary. • Water in the transducers: leave to dry and check that there is no water left, etc. • Dust, debris and grease: try to clean gently, do not used compressed air to clean/blow out any impurities. Above damages/problems will reduce the transmission power significantly which may result in incorrect measurements so that corrective action is required. ...

Therefore the multi‐ transmitter is to be placed (switched on) in the center of either the tank top or tween deck of the hold in question or on top of the cargo in the open uncovered hold. The OHV measurement is then to be made at hatch coaming level pointing down the receiver’s sensor to the multi‐transmitter. Alternatively, and depending on the hold design, the OHV can be taken from an access hatch (provided there are no obstructions between the transmitter and the operator’s SDT 270 (e.g. trunks, …) Important note: operators should always carry out the test with the same sensor (internal or flex) with which they have taken the OVH. Switching of sensor during the test will result in non‐conforming test readings/measurements. Whilst taking the OHV, the operator will have the possibility to adjust the headphone sound level of the OHV so that the max sound of the OHV is not too loud for comfort. However, once the OHV has been taken and confirmed, this sound level cannot be changed anymore until the next OHV for another hold is taken. 39/60 File name: MAN.MAS.EN‐‐02X‐‐Sherlog‐Master‐user‐manual‐Eng.docx...
