Introduction: This meter is a contact and non-contact tachometer.It combines the accuracy & quick measurements and high RPM measurement of a modern laser tachometer. It provides measuring range of 2.5~99,999RPM (laser), 0.5~19,999RPM (contact) and surface speed is displayed in both m/min & ft/min. Features: Laser photo & surface contact measurements With Auto Ranging and automatic low power indication LSI-circuit and crystal time base mechanism for high accuracy & fast measuring time Last value, maximum value and minimum value Insignificant zero suppression Durable & light weight Specifications: Measure in ft/min and m/min Display : 5 digits, 10mm LCD with function annunciation Measurement Photo Tach : 2.5 ~ 99,999 RPM Contact Tach : 0.5 ~ 19,999 RPM Surface Speed : 0.05 ~ 1,999.9m/min 0.2~ 6,560 ft/min Resolution:Accuracy : ±(0.05% +1 digit) Photo Tach : 0.1RPM (2.5 ~ 999.9 RPM) 1 RPM(over 1,000 RPM) Contact Tach : 0.1 RPM (0.5 ~999.9 RPM) 1 RPM(over 1,000 RPM) Surface Speed : 0.01 m/ min.(0.05~99.99 m/min) 0.1m/ min.(over 100 m/min) Surface Speed : 0.1ft/min (0.1 ~ 999.9 ft/min) 1ft/min (over 1000 ft/min) Sampling Time : Photo Tach (1 sec,over 60 RPM); ContactTach (1 sec, over 60 RPM) Photo Tach.
