Checking Speed Measures with EM Log Tester
You can check the speed measures of the sensor using an EM Log tester.

Sensor Configuration
Learn how to configure the sensor settings.
- Connecting the Sensor to Mosa2
  To configure the sensor, you need to connect it to Mosa2 application, using either the Dock or the Configuration Cable.
- Battery Information
- About the Virtual Water Switch Option
  Mosa2 has a virtual water switch option that changes the conditions under which the sensor is running.
- Diagnostic Information
  Scala2 and Mosa2 applications warn the user in case of water ingress in the sensor.
- Configuring the Trawl Node
  You need to give a trawl node to the sensor. It is the number corresponding to the position of the sensor on the trawl.
- Configuring the Uplink Frequency and Power
  Configure the settings of the communication link between the sensor and the vessel.
- Configuring the Echo Sounder
  Configure the echo sounder settings of the Speed Navigator.
- About the Automatic Range Mode
  The sensor has an automatic range mode that is useful to get better quality echograms when the trawl is close to the bottom.
- Checking Speed Measures with EM Log Tester
  You can check the speed measures of the sensor using an EM Log tester.
- Applying Offsets to Measurements
  You can apply offsets to temperature and depth measurements if the measured values do not correspond to the environment of the sensor.
- Testing Measures
  You can test the measures taken by the sensor (e.g. battery level, temperature, depth) to check that there are no faults.
- Memory Card Recording
  This topic explains the memory card recording feature (this feature is optional).
- Saving a Configuration on Mosa2
  You can save different configurations of the sensor to be able to quickly change the configuration when you change your fishing method.
- Exporting Sensor Configuration
  You can export the sensor settings you configured on Mosa2 on a file. You can afterward use this file when configuring a similar sensor.
- Importing a Sensor Configuration
  You can apply to a sensor a configuration that has already been made on another sensor.

Checking Speed Measures with EM Log Tester

You can check the speed measures of the sensor using an EM Log tester.

Before you begin

The speed of the sensor is calibrated.
The sensor is connected to Mosa2.

About this task

If you do not have the EM Log tester, please refer to your local Marport sales office.

The EM Log tester is also useful to check that the sensor is still operational over time. You can check speed before every fishing campaign to make sure the sensor works properly.

Procedure

From Mosa2, click Menu > Expert and enter the password copernic.
Go to the Measurements page, then click in Emlog Speed.
Put the EM Log tester on the EM Log pins according to the following picture. Make sure the 4 pins are correctly aligned and hold still the EM log.

Tip: You can place a double-face adhesive tape at the center of the four pins to stick the tester to the EM log pins.
Click EMlog Test.
The along speed must be between 2 and 3 knots for a standard installation (1.10 Along Gain) and 2.5 to 3.8 for a reversed installation (1.26 Across Gain), and the across speed must be between -3 and -2 knots.

Troubleshooting: If the along speed is negative and the across speed positive, it means that you placed the EM Log tester upside down.
Troubleshooting: If an error message says the offset and gain are incorrect or the EM log tester is broken, it may be because the EM log tester was not totally immobile during the test. Consider using double-face adhesive tape to stick the tester to the pins.
