Error message
Reason
“Hi” or “Low” is displayed when the temperature
measured is outside the HAL and LAL limits.
“Er 2” is displayed when the ambient temperature
changes quickly. “Er 3” is indicated when the
ambient temperature falls below 0 °C (32 °F) or
e50 °C (122 °F). Allow at least 30 minutes
for the thermometer to adapt to the room
temperature.
“Er 5” … “Er 9” means that you must reset the
thermometer. To do so, turn the device off, remove
the battery and wait for at least one minute before
you reinsert the battery and turn the device back
on. If the error remains, please contact PCE
Instruments.
“Hi” or “Lo” is indicated when the temperature
measured is outside the measurement range.
7 Storage and cleaning
The device should be stored at room temperature. The sensor lens is the most sensitive part of the
thermometer. Therefore, it should always be kept clean. Please be careful when cleaning it. Use a soft
cloth or cotton swab with water or medical alcohol. Do not submerge any part of the instrument.
8 Batteries
The battery level indication can be as follows:
“Battery OK”: measurements are
possible.
“Battery low”: measurements are
still possible, but battery needs
to be replaced.
“Battery flat”: measurements are
no longer possible.
When the “Battery low” icon appears, the battery should immediately be replaced by a new 1.5 V
AAA battery. To avoid malfunction, please switch off the device before replacing the battery.
Dispose of used batteries immediately and keep them away from children.
For the disposal of batteries, the 2006/66/EC
directive of the European Parliament applies. Due to the
contained pollutants, batteries must not be disposed of as household waste. They must be given to
collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or
give them to a recycling company which disposes of the devices in line with law.
