*1 Linearity was obtained using KEYENCE's standard target (Zirconia block gauge: LK-031/036, LK-081/086, LK-011, White ceramic block gauge: LK-501/503). *2 Repeatability was obtained using KEYENCE's analogue sensor controller (RD-50) with the number of averaging measurements set to 64. Note: The ripple of the analogue output may be 1 mV or more due to co mmon mode noise when observed with an oscilloscope or a high-speed A/D conversion board. *3 When measurement is impossible, 12 V (31.2 mA) is output.
