IRT 4520:
This model stores the last 8 temperature measure- ments. To display the stored measurement, the thermometer must be turned on. Then press the «I/O» button for at least 1 second. The display shows the memory number (e. g. MEM 1), and when releasing the «I/O» button, the stored temperature for that memory number is displayed, together with «MEM». If «I/O» button is pressed too long, the thermometer will be switched off. Each time the «I/O» button is pushed, the remaining memory numbers are displayed (up to MEM 8).
MEM 1 is the most current reading, MEM 8 is the oldest.
The memory mode is left automatically after displaying the oldest reading, or after pressing the «I/O» button for at least 1 second.
