If your ZL6 data logger is not working as expected, use this guide to diagnose and resolve common issues.

Visual inspection
  1. Please make sure all sensors are plugged in securely and fully inserted into the port. 
  2. Inspect sensor cables for damage, cuts, abrasions etc.  
  3. Ensure all 6 batteries are oriented in the correct position.   | + | - | + | - | + | - |
  4. On the computer board, is there any corrosion or rust visible? 
ZENTRA Utility

To connect to the logger you need a USB to Micro-USB cable. The cable type used must be able to transfer data, not just power. If a connection cannot be made, try a different cable.   

  1. Open ZENTRA Utility
  2. In the drop-down you should see an option for “ZL6“.
  3. Click Connect. 
List carriers
  1. Click Actions
  2. List Cellular Carriers
  3. Click Start to begin the test

When the test is complete a list of cellular carriers in the area will be shown. If the test fails move a few feet and try again.  After the test successfully lists a cellular carrier, proceed to the next step. 

Communications test
  1. Click Actions
  2. Communication Test
  3. Click Test to begin the cellular communication. 

When the test is complete the signal strength, carrier, packet attempts and status of the test will be displayed. If the test fails or has low signal, move a few feet and try again.  

For the best signal the antenna should be unobstructed by structures or vegetation. If required an extension cable can be used to elevate the antenna. See the ZL6 ANTENNA EXTENSION guide.

Sensor connection issues

To check sensor communication to the logger when there is no visible damage open ZENTRA Utility.

  1. Press the SCAN button

What to try if the scan result is "invalid input" or an unreasonable measurement value:

  1. Manipulate the cable at the stereo end while scanning and observe the result.
  2. Unplug and plug the sensor then scan again.
  3. Clean the connection. Use isopropyl alcohol if available or water and a clean cloth.
  4. Plug the sensor into a different port and repeat the scan.  
  5. Try a different sensor in the port that was giving errors.

If the sensor responds when moving it to a different port the device will need to be sent in for repair.

If the sensor responds when the cable is manipulated the cable or connector sensor is bad and should come in for repair/replacement.

Device firmware

Device firmware should be kept up to date. To check for updates,

  1. Click Help
  2. Check for Firmware Updates
