The frequency of measured power spectrum is output after being
converted to the pulse signal. Therefore, the displayed value may
differ from the frequency of pulse output when the rotational
speed is selected as a display.

FT-2500
When installing the FT-2500, the following precautions should be taken care of.
Some installation conditions may give adverse influence against the noise tolerance.
•
Separate the power supply cable of the FT-2500 from the power line which is connected to high-power
load.
•
Be sure to use the power supply cable which is provided as standard accessory.
•
Do not arrange the wiring of the FT-2500 cables in parallel or together with the power line.
•
Do not extend the sensor signal cable longer than necessary.
•
Use cables of 5m or less in length for DIGITAL-I/O and V-OUT.
•
Use a shielded cable as the signal cable. In addition, be sure to ground the shielding wire.
•
Keep the FT-2500 as far away as possible from devices, which are generating the strong high-frequency
signal or surge.
•
Keep the FT-2500 and its cables away from devices, which are generating the strong electric and
magnetic fields.
•
Be sure to connect the FT-2500 to protective ground.
•
When installing the FT-2500 inside a control or measurement panel, ground the instrument shielding wire
to the panel and also ground the control or measurement panel.
•
If it is subject to influences by electrical strong noise or surge, use a surge killer and noise filter inside the
control or measurement panel as shown in the figure left.
*
It is requested to wire the signal cable as short as possible. Keep the minus side of the surge killer within
50 cm. Ground both ends of the shielding wires of all input/output signal cables to the ground terminal of
the panel.
