Capacitor Test

If a commercial capacitor checker is not available, the following test may be made:

1.Briefly short the capacitor terminals together with a screwdriver.

2.Disconnect a wire from either capacitor terminal.

3.Adjust an ohmmeter to a high value such as RX10K or RX1 Meg.

4.Connect the ohmmeter leads to the capacitor terminals.

5.A good capacitor will cause the indicator to move quickly to zero ohms, then slowly return to infinite ohms. An open capacitor will not cause any indicator movement; a shorted capacitor will give a continuous zero ohms reading.

6.If the test is to be repeated, the capacitor terminals must again be shorted together briefly.

Diode Test

1.You must have a #308 ct. Everready continuity tester or equivalent/

2.Desolder both wires from the diode lead connections. (Clamp heatsink pliers on the diode leads to avoid damaging the diodes.)

3.Attach one of the test unit leads to either diode lead.

4.Attach the other test unit lead to the diode heatsink.

5.Turn the test unit on and note if the test unit bulb lights.

DANGER: Reversing charge or polarity of wiring couldcausebatteriestoEXPLODEcaus- ing serious bodily harm to yourself or others.

6.. Reverse the test unit leads in Steps 3 and 4.

7.Turn the test unit on and note if the test unit bulb lights.

8.Good diode - test light bulb should light up in one of Steps 5 and 7 and not in the other.

Defective diode - test bulb will light up in both Steps 5 and 7.

Defective Diode - Test bulb will not light up in either Steps 5 or 7.

SPS-28 specifications

The Clarke SPS-28 is a cutting-edge marine navigation system designed to enhance vessel safety, efficiency, and performance. This innovative system integrates advanced technologies to provide real-time data and analytics, improving situational awareness for operators in various maritime environments.

One of the standout features of the Clarke SPS-28 is its robust Global Navigation Satellite System (GNSS) integration. The SPS-28 uses multiple GNSS signals, ensuring high accuracy and reliability, even in challenging conditions. This multi-constellation support allows the system to maintain precise positioning for vessels navigating through busy ports or remote areas alike.

Another key aspect of the SPS-28 is its advanced radar capabilities. The microwave radar technology employed in the system allows for accurate object detection and tracking in all weather conditions. The radar’s long-range capabilities enable users to identify potential obstacles or vessel traffic well in advance, giving operators ample time to make informed navigational decisions.

The user interface of the SPS-28 is designed for simplicity and ease of use. Featuring a high-resolution touchscreen display, the system allows users to quickly access essential data, including navigational charts, AIS (Automatic Identification System) information, and vessel performance metrics. The intuitive graphical interface minimizes the operator’s workload by presenting critical information in a clear and concise manner.

Safety is a paramount consideration for the Clarke SPS-28. The system includes built-in safety features such as collision avoidance alerts and anchor watch functionalities. These features provide real-time alerts to prevent potential accidents, ensuring that vessels can navigate safely in congested waters or during challenging weather conditions.

In addition to navigation, the SPS-28 is equipped with several communication technologies, including VHF radio and satellite capabilities. This connectivity ensures that vessels remain in contact with other ships and shore-based operations, facilitating smooth coordination and response during emergencies.

Furthermore, the SPS-28 is designed with adaptability in mind, able to integrate with other onboard systems such as autopilot, engine management, and environmental monitoring tools. This integration enables a comprehensive approach to vessel management, streamlining operations and maximizing efficiency.

Overall, the Clarke SPS-28 represents a significant advancement in marine navigation technology, offering a suite of features that enhance safety, performance, and operational efficiency for modern seafaring vessels. With its state-of-the-art technologies and user-friendly design, it is an invaluable asset for mariners navigating the complexities of today’s maritime challenges.
