Troubleshooting: Other Pocket Digitals

Here are answers to the questions our Tech Support team is asked most often about our pocket digital thermometers.

(See this comparison chart to determine which pocket-digital thermometer is right for you.)

Question (applies to all models): My thermometer is displaying an LLL or HHH error. What does it mean?

There are several reasons your thermometer may display either an LLL or HHH error, the most common being that the probe was damaged or broken.

If your thermometer may have been exposed to temperatures above or below its temperature range (see below for your model), you will see one of these errors. The errors may also indicate that there are other types of damage to the probe.

Sometimes, doing a hard reset will resolve the problem. Remove the battery. Leave the battery out for at least one minute before installing a new battery.

If you need additional help, please contact our Tech Support team. Their contact information is below.

How do I test my thermometer for accuracy?

The best way to test your thermometer for accuracy is with a properly prepared ice bath test, as it a standard laboratory test that is easily replicated at home. Directions for making a proper ice bath are found here.

If your thermometer is accurate within specs (found below), you can rest assured that it is reading accurately in food and at higher temperatures.
