thumb. Note that this illuminates the display window. The
display should show “
0
”, either with the letters “
rpm
” directly
below it or with the letters “
m/min
” below it to the left,
depending on the position of the function switch.
To simulate a speed measurement
, keep the tachometer
cradled in your right hand and spin its shaft by “flicking” it
with the middle two fingers on your left hand while pressing
the
Measurement
button with your right thumb. Note how
the display tracks the force of your flicks, and also how the
instrument powers off whenever the
Measurement
button
if released (this “dead man switch” feature extends battery
life considerably).
To simulate storing measurements
, keep the
Measurement
button depressed with your right thumb while
you make three simulated speed measurements, as follows:
• Flick the shaft with your left index finger once. Store the
displayed reading by pressing the
MEM
button with your
left thumb.
• Flick the shaft again to make another simulated
measurement. Store this reading by pressing the
MEM
button again.
• Flick the shaft a third time and store the third reading as
well by pressing the
MEM
button.
After simulating and storing three measurements, release
the
Measurement
button and do not press it again until
instructed to.
