Why is my KM28B displaying ‘OL’?

Why is my KM28B displaying ‘OL’?

If you own a KM28/KM28B Thermocouple Food Thermometer and it is displaying ‘OL’ on the LCD Screen, as shown below, this could be for a couple of reasons.

Why is my KM28 displaying 'OL'?

The ‘OL’ message will appear if your KM28/KM28B Thermocouple Food Thermometer is turned on without a Probe connected via the device’s sub-miniature connection.

If a suitable probe has been connected via the sub-miniature connection on the front of the device and the ‘OL’ error is still being displayed, then this can indicate a fault with the connected probe.

In this instance we would recommend that the probe in question is disconnected from the device and a new or alternate probe is connected instead.

Should the ‘OL’ error message persist, despite alternate probes being connected and tried, then the Thermometer(s) in question will need to be returned to our Service Department for repair.

My Device is showing unrealistic temperature readings

My Device is showing unrealistic temperature readings

If you have set up your Device correctly, inserted a Sub-Miniature Connector Probe into your Device and taken a temperature reading, only to discover that the temperature recorded is vastly different to that which was expected, then it may be that the Probe Connector was in fact inserted incorrectly.

The Sub-Miniature Connector on all Comark Probes has two prongs, one slightly larger than the other. These prongs are also marked as positive (+) and negative (-) on the cable head itself, as shown below.

Sub_Min_Right_Way_Round_c

The prongs correspond to two similarly shaped slots on the Device, one slightly larger than the other.

In some cases, it may be possible to force the prongs of the Sub-Miniature Cable Connector in the wrong way around. If this is done then the symptoms would be as described above, recorded temperatures that are vastly different to those which were expected.

Sub_Min_Wrong_Way_Round_c

To resolve such an issue, simply unplug the Sub-Miniature Cable Connector, check the prong orientation and then re-insert.

  • Small Slot = Positive
  • Large Slot = Negative
