Gauge error table
1 Scope
This standard specifies the basic error limit gauges and hysteresis, tapping displacement allowable value, ambient temperature, etc. indication errors.
This standard applies to the elastic element is different sensor accuracy class, measuring range of the gauge (the meter).
This standard specifies the instrument operating ambient temperature deviates from the reference temperature indication of the margin of error, this standard applies only to the elastic modulus of the material
The temperature coefficient "K" of the instrument 0.04%/℃ of.
