Page 14: Tachometer Mode
8.0 TACHometer Mode Tachometer measures speed or linear rate with respect to time. Time intervals are sceonds, minutes, or hours. Rotational speed can be measured in Revolutions (Revs) per second, per minute, or per hour. The most common measurement is RPM or Revs per minute using the optical tachometer mode. 8.1 TACHometer Setup Turn Last Units selected... - Page 15 RPS, RPM or RPH Enter selection of Units Select Units Repeat until desired Units displayed Save and advance Enter selection NONE, 1, 2 or 3 of number of decimal places 10.
