*1. The measurement may become saturated if the Sensor is too close to an object being measured, even if it is within
       the measurement voltage range. Use the distance from the measurement surface (mm) times 1 KV as a guide.
*2. This is the minimum value obtainable when a ZJ-SDA11 Amplifier Unit is connected.
*3. When the ambient temperature is stable at 25°C.
*4. When the measurement distance is 10 mm and the measurement voltage is -5 to 5 KV.
*5. When a Preamplifier is used (excluding the Sensor Head).

*1. The response time of the linear outputs is calculated as follows: Measurement period × (Average count setting + 1).
       The response time of the judgment outputs is calculated as follows: Measurement period × (Average count setting +
       1).
*2. The output can be switched between a current output and voltage output using a switch on the bottom of the Amplifier.
*3. Setting is possible using the monitor focus function.
