There are two main causes for this.
- Getting a new unit and placing it straight in a fridge without starting it
- Stopping it to retrieve results, and not restarting it
The problem is quite simple – the unit is off and has no idea what is happening.
This problem tends to lead to some awkward follow-on questions like
- “How do I retrieve the readings then?” (You can’t)
- “So how can I get the results?” (You can’t)
- “Is there anything I can do to get the results?” (No)
Ways to avoid the problem include:
- Don’t stop the logger when retrieving results. Ensure that “rollover” has been enabled.
- Use a logger like the Logtag that has flashing red/green LEDs to indicate that it has started.
- Train your staff.
And this is our most commonly reported mistake. In my next post, we’ll discuss the most common mistake that is rarely mentioned to us.
