1. Calibration material
MODEL FK-602F Transducers are calibrated for JIS SCM440 flat
surface (more than 54 mm dia.).
If the measured target is other than JIS SCM440 flat surface, it will
present a different characteristics. In such a case, calibration by the
connected equipment (e.g. monitor) side should be required for
system operation.

2. Shield wire connection

Connect shield wire of signal cable (3-wire shielded cable between
driver and monitor) to driver's "COM" terminal (Spring lock terminal:
"Shield" terminal) and monitor's "COM" terminal.
If this is not adhered to, noise may be caused.

3. Connector isolation, etc.

The connector connecting the sensor cable and the extension cable
shall be insulated with the attached insulation sleeve (transparent
shrink tube) or fluoro resin insulation tape.
The vinyl-insulating tape shall not be used.

4. Megger test of signal cable

If megger test is made on the signal cable (3-wire shielded cable), be
sure to discharge the charged electric load before connecting the
cable to driver.
If this caution is not adhered the driver could be dameged.

5. Sensor installation

Not available for rain water at out door use.
It may cause the sensitivity change and insulation down.

6. Calibrated as a system

The sensor, extension cable and driver, which are calibrated as a
system, shall be connected with each serial No. as specified in the
inspection test report. If this is not adhered the output characteristics
may be out of specification.
7. Linearity
The linearity margin provides for examination result in our factory. This
regulated value is not applied to the examination result in the site.
8. The instructions manual contains important information such as
conditions necessary for safe handling of the system.
2
Such information and conditions are important and indispensable for
2
ensuring safety. Therefore, be sure to read the instructions manual
thoroughly before handling the system.
9. Cable length 5.0m sensor is designed for 5m system only.
Can not use for 9m system.
