Entering new calibration


I have recently calibrated a Fish Fat Meter for Murray cod. I am now trying to enter this calibration into the fat meter. I am using the calibration module, and following the methods provided. However, when I get to the end of the procedure it keeps coming up with:

Run-time error ‘424’: Object required

I am not really sure when, because I am following methods correctly. The only things I can think of is are the wrong COM port is selected (I have just been plugging the cable into a USB port, and selecting COM 1), or that the calibration data has decimal points (although I tried it with some dummy data without decimals and the same problem was occurring.


The USB Com port will NOT be COM 1… that is you normal serial port COM.


There is a NEW, UPDATED version of our Data Management Software(DMS) on our Website. This makes the creation of custom calibrations a lot easier…

  • Entering custom data is easier
  • You can monitor the graph, as data is addedYou can choose three different graph types… Exponential (default), Linear, and Polynomial.

The light on my charger just blinks and won't stay on


The light on my charger just blinks and won’t stay on.


This would indicate a short circuit at the plug which connects to the Torrymeter. Can you please check that the cables have not been twisted when inserting the plug into Torrymeter… this would cause the wires to come together, inside the plug, causing the charger to indicate a short circuit by flashing led.
