To perform a reset:

Follow the battery removal instructions in “Replacing the Batteries” on page 16.
2. Remove the probe and the probe well from the instrument. Then, unplug the probe
connector by depressing the locking tab and pulling on the connector body. DO NOT pull

3. While watching the display, install the batteries per the instructions in “Replacing the

2.3.2 Power-On Self Test (POST)
The self-test will check the internal microprocessor,
instrument electronics, and display for correct operation.
The instrument performs the self-test series following all
power-on or reset cycles. During the self test sequence the
thermometer displays all LCD segments for 2 seconds.
Concurrently, the thermometer plays the power-on audible
notification and performs necessary self-testing.
