Main Specifications
Conditions: tachometer works normally in ambient temperature 0 ~ 60 ℃, relative humidity below 85%.
Basic error: under 20 ± 2 ℃, the basic error is ±1.5% of  upper limit.
Temperature effect: when environmental temperature changes within regulated range, the indication value (temperature changes every 10℃)should not be over absolute basic error value.

Backlash: indication backlash does not exceed the absolute value of the fundamental error.
Accessories: Each tachometer is equipped with a flexible shaft, flexible shaft length has three standards:230mm, 275mm, 850mm which are optional.
