If you use the instrument in a manner not specified in this manual, the protection
provided by the instrument may be impaired. Yokogawa Electric Corporation assumes no
liability for the customer’s failure to comply with these requirements.
LEDs on the Frequency Module
On the front panel of the frequency module (701281 (FREQ) and 720281 (FREQ)) are
LEDs for each channel. These LEDs allow you to check the input condition of the pulse.

LED
Green: When pulse is applied
Red: When the input voltage level
is over range.
Off:
When pulse is not applied
Example: 701281(FREQ)
Note
• The LEDs on the frequency module illuminate in green when pulse is applied and red when
the input voltage level is over range. It is independent of the start/stop condition of the
waveform acquisition of the SL1000.
• If the frequency module preset (see the
Acquisition Software User’s Manual IM720120-61E
)
is set to “EM Pickup (electromagnetic pickup),” the LED does not illuminate in red even if the
input voltage level is over range.
