Main Specifications
Conditions: tachometer works normally in ambient temperature -20 ~ 50 ℃, 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.
Swing: pointer is allowed to swing slightly when tachometer works, but swing range should not be over absolute value of basic error.
Rotating in the same direction: clockwise one-way rotation, pointer and rotary spindle are of the same direction.
Dust-proof: tachometer has sealing device which is dust-proof.
