If your electric thermometer says 'Lo', it means that the temperature is too low to be measured by the device. This is a common issue with digital thermometers, which are usually designed to measure body temperature. When the thermometer is outside the body, the temperature is usually lower, and the device will display 'Lo' to indicate that the temperature is below its range of measurement. This is not an indication of a low battery, which is usually displayed as Lo batt.
| Characteristics | Values |
|---|---|
| Meaning | Low temperature |
| Low battery | No |
| Low battery sign | "Lo batt" in the corner of the display |
| Display | "Lo" is shown in the display where the temperature is normally displayed |
| Thermostat display range | Lower than 40 F (4 C) |
| Display on start-up | "Lo" is standard practice for most digital thermometers when turning the device on |
| "Lo" indication | Temperature is outside the temperature range |
| Troubleshooting | Check if the thermometer is correctly positioned, press the on/off button to switch off and on again, and re-start the measurement |
| Measuring | Make sure to keep your mouth closed before and while measuring, and only press the on/off button once the thermometer is in the correct position |

What You'll Learn
'Lo' means low temperature
When a thermometer displays "Lo", it means that the device is sensing a temperature lower than its measurement range. This is usually the case when the thermometer is outside the body, as most digital thermometers are designed to measure body temperature. For example, the NC° Thermometer Gen1 can only measure down to 32°C (89.6°F), so if the temperature is lower than this, it will display "Lo".
The "Lo" indication on the thermometer means that the temperature is outside the range of the thermometer's measurement capabilities. This is a standard feature of most digital thermometers, and it does not indicate a low battery, which is usually displayed as ""Lo batt" in the corner of the screen.
If your thermometer shows "Lo", you can try the following:
- Ensure that the thermometer is correctly positioned. For oral thermometers, this means placing the thermometer as far back as possible in the mouth, underneath the tongue, and keeping the mouth closed before and during measurement.
- Press the on/off button to switch off the thermometer, then press it again to switch it on and re-start the measurement.
- Check the connection between the probe and the top of the thermometer. If the connection is bad, the thermometer may display "Lo". Try cleaning the connection with an eraser, an old electronics trick to improve conductivity.
By following these steps, you can address the "Lo" indication on your thermometer and obtain an accurate temperature reading.

It does not mean low battery
If you see "Lo" on your electric thermometer, it means that the thermometer is reading a low temperature. This is usually because the thermometer is reading the room temperature, which is too low for the thermometer to measure. For example, the NC° Thermometer Gen1 can only measure down to 32°C (89.6°F), so if the room temperature is lower than this, the thermometer will display "Lo".
It is important to note that "Lo" does not indicate a low battery. If the battery is low, the display will usually show "Lo batt" in the corner of the screen. The "Lo" indication means that the temperature is outside the thermometer's measurement range. This is a standard feature of most digital thermometers, which are designed to measure body temperature.
If you see "Lo" on your thermometer, you can try adjusting the way you measure. Ensure that you place the thermometer as far back as possible in your mouth, with your mouth closed, and underneath your tongue, right at the root. You can also try troubleshooting steps such as checking the connection between the probe and the top of the thermometer and ensuring that the thermometer is correctly positioned.
In the case of an infrared thermometer, "Lo" may indicate that the current ambient temperature is outside the range of the thermometer's measurement requirements or that there are fast changes in the environment temperature. In this case, it is recommended to keep the thermometer in an appropriate environment for 20-30 minutes to avoid this situation.

The thermometer may be measuring room temperature
The "Lo" indication on an electric thermometer means that the device is sensing a temperature that is outside its range. Most digital thermometers are designed to measure body temperature, so when they are outside the body, they usually sense a lower temperature and display "Lo". This is why the thermometer may be measuring the room temperature.
The room temperature is usually too low for most digital thermometers, which often have a minimum measurement threshold. For example, the NC° Thermometer Gen1 can only measure down to 32°C (89.6°F). If the thermometer is exposed to a temperature lower than this threshold, it will display "Lo".
In some cases, the thermometer may display "Lo" due to a bad connection between the probe and the top of the device. Users have reported that they were able to fix this issue by taking the device apart and cleaning the connection between the probe and the top with an eraser.
It is important to note that "Lo" does not indicate a low battery. The low battery sign is typically displayed as "Lo batt" in the corner of the screen. If the thermometer shows "Lo", it is recommended to check if the device is correctly positioned and then turn it off and on again to re-start the measurement.

The thermometer may be positioned incorrectly
If your thermometer is displaying 'Lo', this typically means that the thermometer is reading a low temperature. This is not an indication of a low battery—the sign for this is usually \"Lo batt\" in the corner of the display. Instead, 'Lo' means that the thermometer is reading a temperature that is lower than its lower limit. For example, the NC° Thermometer Gen1 shows 'Lo' when the temperature is below 32°C (89.6°F).
If you are using an infrared thermometer, 'Lo' may indicate that the current ambient temperature is outside the range of the thermometer's measurement requirements or that there are rapid changes in the environment temperature. In this case, you should keep the thermometer in an appropriate environment for 20-30 minutes to allow it to adjust.
If the thermometer continues to display 'Lo' after addressing the positioning, you may need to troubleshoot further. Check the connection between the probe and the top of the thermometer, as a bad connection can lead to an inaccurate reading. Additionally, consider completing a measuring training program, which can help you ensure that you are using the thermometer correctly and that all components are functioning properly.

The thermometer may have a bad connection
If your electric thermometer is displaying "Lo", it is likely that it is indicating a low temperature reading, rather than a low battery. However, it could also be the result of a bad connection.
Bad connections can occur due to a variety of reasons. Firstly, a low battery can cause connection issues, especially if the device has not been fully charged. In such cases, ensure that the thermometer is charged to full battery life before attempting to use it again.
Another common cause of connection issues is physical barriers between the thermometer and the device it is trying to connect to. Certain materials, such as metal, concrete, brick, and certain types of glass, can interfere with Bluetooth signals. Ensure that there are no such barriers between the thermometer and the device, and that both are within close proximity of each other.
Wi-fi interference can also cause connection problems. Your smartphone or mobile device may experience interference from its Wi-fi router, preventing it from pairing with your thermometer via Bluetooth. Try moving away from the Wi-fi source or power off the Wi-fi router temporarily to see if this resolves the issue.
If the issue persists, try resetting your thermometer. Power off both devices, then go through the resetting process for your thermometer. Once they are powered back on, select the "forget this device" option for the thermometer in your smartphone's Bluetooth settings. This will force your phone to recognize the thermometer's Bluetooth signal as new, increasing the chances of a successful connection.
If the problem still persists, there may be damage to the sensor's components or connections. This could be due to environmental factors such as extreme temperatures, humidity, corrosive chemicals, or physical damage. Mechanical stress, electrical overload, or issues with the temperature controller setup could also be contributing factors. In such cases, it is recommended to consult a professional or the manufacturer for further guidance and repair options.
