  1. What are the dimensions of the DCM100 current transducers? The DCM100 is packaged with a Hall Effect sensor (P/N: LEMHTA200-S) which is rated to measure currents up to 200 Amperes.If your application requires measurements exceeding 200 Amperes,  Maretron offers additional sensors:400 Amperes measurement. Use... Read More
  2. What are the specifications for the Current Transformer (CT) that comes with the Maretron AC Monitor (ACM100)?  The ACM100's current transformer specifications are as follows: Part Number: M000630Current Range: 100 AmpsOutput Ratio to Input: 1000:1 (100maAC Max)Frequency Range: 45-60HZDielectric Withstand: 1000VAC (RMS)Insulation resistance Class: .5KVFu...

  3. What happens when I use the TLM100/150 without a focus tube? A focus tube is recommended for tank applications that experience a drastic level change when the vessel is underway.The TLM100 transmits an ultrasonic pulse that allows the device to calculate the distance from the sensor to the fluid surface (simil...

  4. Why is the DST110 Speed Through Water (STW) reading different from the Speed Over Ground (SOG) reading? Speed Over the Ground (SOG) is the speed of the vessel relative to the surface of the earth. Speed Through Water (STW) is the speed of the vessel relative to the water. It is possible for the STW to be zero while the SOG is 5 knots, for example if th... Read More
  5. Why is the GPS100 Speed Over Ground (SOG) reading different from the Speed Through Water (STW) reading? Speed Over the Ground (SOG) is the speed of the vessel relative to the surface of the earth. Speed Through Water (STW) is the speed of the vessel relative to the water. It is possible for the STW to be zero while the SOG is 5 knots, for example if th... Read More
  6. How do I make the SSC200 agree with other compasses on the vessel, or, in other words, how do I align the SSC200 with the boat? The SSC200 compass is aligned with the vessel by pointing the arrow shown on the top of the compass towards the bow. There are alternative mounting options, which can be found the users manual. Once you have performed magnetic deviation calibration o... Read More
  7. Why is the WSO100 wind direction incorrectly displayed on my display? The WSO100 will not show the correct wind direction if it hasn't been aligned with the boat. You align the WSO100 in one of two ways:align the post (there are three posts attaching the top of the WSO100 to the base) closest to the humidity senso... Read More
  8. What is ground wind? Ground wind is the speed and direction of the wind referenced to a compass rose, which is different from apparent and true wind which are referenced to the bow of the boat. The apparent and true wind are interesting to see how the wind is affecting o... Read More
  9. What is true wind? True wind is what the wind is truly doing and it can be computed from the measured apparent wind by subtracting the vessels speed. For example, if the vessel was moving at exactly 5 knots and the wind was blowing in the exact opposite direction at 5 ... Read More
  10. What is apparent wind? Apparent wind is what the Maretron WSO100 measures and doesn't necessarily reflect what the wind is truly doing. For example, if the vessel was moving at exactly 5 knots and the wind was blowing in the exact opposite direction at 5 knots, then t... Read More
