Conditions: tachometer works normally in ambient temperature -20 ~ 50 ℃, relative humidity below 85%.
Basic error: under 20 ± 2 ℃, the basic error is ±1% 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.
