The above values indicate the deviations observed 30 minutes after the power is turned ON. (The resolution is measured with Omron's standard reference object at ½ of the measurement range with the ZX-EDA set for the maximum average count of 4,096 per period.) The resolution is given at the repeat accuracy for a stationary workpiece, and is not an indication of the distance accuracy. The resolution may be adversely affected under strong electromag- netic fields. *2 Linearity: The linearity is given as the error in an ideal straight line displacement output when measuring the standard reference object. The linearity and measurement values vary with the object being measured. *3 The value given is for an ambient temperature of 25°C. *4 Temperature characteristic: The temperature characteristic is measured with Omron's standard reference object at ½ of the measurement range. *5 The ambient temperature given is only for the sensor head. It is -10 to 60°C for the preamp. *6 Do not use in moist environments because the case is not waterproof.
