ADJUSTMENT
Before starting measurements, adjust the analog output with
an actual target using the following procedure.
Connection
1. Connect a panel meter or voltmeter to the analog output
terminal of the controller using a shielded cable.
2. Complete the connections and then turn the power ON. The
POWER indicator of the controller lights and the sensor is in
operation mode.
* Before starting the adjustment procedure, allow the unit to
warm up for at least 30 minutes.
Setting the switches
1. Set the response time selector switch according to the required
measurement accuracy.

3. Set the cable length selector switch accord-
ing to the sensor head cable length.
4. Set the lock switch to FREE (the upper
position).
■ Analog output adjustment
1. Place the sensor head in contact with the target and press the
<1> key (zero-point set key) to check whether the output
voltage is 0 V.
Hold the sensor head in contact with the target
until the LED of key <1> goes out.
2. Set the distance between the sensor head and the target to the
maximum measuring distance. Then press the <2> key (Full-
scale set key) to check whether the output voltage is 5 V.
Hold the sensor head at the maximum measuring
distance from the target until the LED of <2> key
goes out.
