4.1 Rotational Speed
After starting the instrument, the first menu is rotational speed, in RPM or
in Hz, and these units can be chosen in the Settings menu. Speed can be
measured both using laser (and reflective tape), or using the available tips
included in the case with the TKRT 21 Tachometer. The Tachometer detects
automatically if the laser is being used or if a tip is being used. When a tip is
used, the laser is not activated.
The speed measurement can be used in two different ways:
Short press (< 0.5 s) on button "measure" (3) activates the laser and
A.
starts a continuous measurement. Another short press on (3) turns the
measurement off.
Long and continuous press (> 0.5 s) on button "measure" (3) activates
B.
the laser as long as the button is pressed.
Fig. 4 – Example
• Units can be changed in the Settings.
• When measuring, a dot is used to indicate decimals.
• Measuring time appears when a measurement starts,
when a signal is detected from the laser or a tip.
• Laser icon is displayed when the laser is used to measure a speed.
