# [TEMPERATURE RESOLUTION DEFAULT VALUE](#TEMPERATURE_RESOLUTION_DEFAULT_VALUE)

## [tempres](#tempres)

*read-write, integer*  
The device employs a non-volatile memory to store the default temperature resolution (9, 10, 11 or 12 bits) to be applied after power-up. This is useful if you use *simultaneous* temperature conversions. Reading this node gives you the value stored in the non-volatile memory. Writing sets a new power-on resolution value.

As a side effect, reading this node resets the temperature resolution used by *simultaneous* temperature conversions to its power-on value. It also affects the resolution value used by **latesttemp,** to scale the latest conversion value, so make sure to re-sample the temperature before accessing **latesttemp** after writing or reading the **tempres** value.
