1. CALIBRATION MATERIAL
MODEL FK-143F Transducers are calibrated for JIS SCM440 flat surface
(more than 81mm 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, which may cause the wiring
trouble in the case of temperature more than 80°C.
The connector shall not be located in the oil environment.
The oil penetration to cable through the connector may cause the sensitivity
change, due to the change of the cable capacitance.
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.

NOTICE
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. SAFETY BARRIER
In case of the intrinsically safe specification, the approved following safety
barrier is recommended.
•
MTL 7796-
9. The instructions manual contains important information such as conditions
necessary for safe handling of the system.
Such information and conditions are important and indispensable for ensuring
safety. Therefore, be sure to read the instructions manual thoroughly before
handling the system.
10. Cable length 5.0m sensor is designed for 5m system only.
Can not use for 9m system.
