About 30 mA
2.2 Memory Function
When the power is ON, we can check the
MAX/MIN/ LAST
value by keep pressing the
?
MEM

button. The
LCD
display MAX
value first,then
MIN
value, finally
LAST
value.
2.3 Battery replacement:

appear on
the display.

Open the battery door and remove the
battery.

I
nstall the new batteries (3pcs AAA
battery) properly.

If the unit will not be used for a long time,
take out the batteries to prevent leakage of
the battery.
2.4 Notes:
There are 3 kinds of rubber tip for rotating
speed measurement. The big cylinder-
shaped and cone-shaped are suitable for
low speed meas urement, the small cone-
shaped is suit ablefor high speed mea
surement. as shown below:
