MEMORY
The memory button is able to recall the records from the last time the

time. The first time the button is pressed, the maximum recorded value is
shown, alternated with “UP.” See Fig. 2.
Figure 2
The second time the button is pressed, the minimum recorded value is
shown, alternated with “DN.” See Fig. 3.

The third time the button is pressed, the last recorded value is shown,
alternated with “LA.” See Fig. 4.

The fourth time the button is pressed, there will be a countdown from 20
to 1. After this, the display will show “An **.” The number that is displayed
after “An” is the number of seconds that the tachometer was recording for
during the last session. In the case of Figure 5, the tachometer recorded
for 64 seconds.
Figure 5
Each time the button is pressed after that, it will show the recorded value
for each second it was recording. After having gone through all of the
values, pressing the button will start from the beginning with the
maximum measurement.

When the batteries need to be replaced, the battery icon will appear in the
bottom left corner of the display. To replace the batteries, slide the battery
cover off of the tachometer and remove the 4 batteries. Install the new
batteries in the same position as the previous ones.
