OPERATION:

Refer to Figure #3.
The memory tachometer will operate in a normal manner with the front toggle switch in the
“TACH” position and will be recording the maximum attained RPM. Changing the toggle switch
to the “MEMORY” position will move the needle to the stored RPM. Pressing the “PUSH TO
RESET” button erases the tachometer memory.

NOTE: Memory is valid for 20 minutes. Maximum RPM may be shown slower if checked after
the 20-minute period.
