General Tools and Instruments CT6235B - Manual (Page 8)

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 Measure-
ment 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 measure-
ment. 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 in-
structed to.
To simulate recalling stored measurements, press the
MEM button once and hold it. This illuminates the display,
which now shows the highest of the three readings you have
just stored. Note that if you continue holding the MEM button,
the display alternates between showing
the highest value and the letters “UP”,
signifying the maximum speed.
