What to do if my Jumper Thermometer displays "Er1"?
If your Jumper Thermometer displays "Er1", it means the ambient temperature is either lower than 10°C (50.0°F) or higher than 40°C (104°F). To resolve this, take a measurement when the ambient temperature is between 10°C (50.0°F) and 40°C (104°F).
Why my Jumper JPD-FR202 Thermometer fails to power on?
If your Jumper Thermometer fails to power on, there are a few potential causes: * **Low battery:** Change the batteries. * **Incorrect battery installation:** Ensure the batteries are installed with the correct polarities. * **Damaged thermometer:** Contact the manufacturer for assistance.
What to do if my Jumper JPD-FR202 Thermometer reading is too high?
If your Jumper Thermometer shows a temperature reading higher than the typical body temperature range, it could be due to a damaged temperature probe. In this case, contact the manufacturer.
How to fix low temperature readings on Jumper JPD-FR202 Thermometer?
If the temperature reading on your Jumper Thermometer is lower than the typical body temperature range, consider the following: 1. **Dirty lens:** Clean the lens of the temperature probe using a cotton swab. 2. **Excessive distance:** Move the thermometer closer to the target. 3. **Recent cold exposure:** Wait for more than 30 minutes after the thermometer is moved into the measurement environment before using it.
