4.6 ERASING THE MEASUREMENT MEMORY
To initialise the measurement memory, press simultaneously on MEM when switching On with the
rotary switch and do not release until it is erased. The MEM symbol lights up, the Init message is
continuously displayed (top right) for 3 seconds and the number of addresses available appears on the
digital display.
After 3 seconds Init ashes once and a beep indicates that the memory has been erased. The number
of addresses available then changesto 1920 which is the maximum capacity of the memory.
Note:
Before the beep you can release the MEM button at any time. In this case, it will not be erased.
