DT-100A Tachometer
Operation Manual
• When using the 6” wheel, do not use the extension shaft - the wheel
may fly off the shaft and cause damage.
• Although the tachometer alone is able to achieve the higher ranges
listed in the Range and Accuracy table on page 3, the wheel at-
tachment has a maximum speed limitation of 5,000 FPM (for safety
reasons).
