If the instrument is used in a manner not specified in this manual, the protection provided by the
instrument may be impaired. YOKOGAWA assumes no liability for the customer’s failure to comply
with these warnings and requirements.
LEDs on the Frequency Module
On the front panel of the frequency module (701280 (FREQ)) are LEDs for each channel. These LEDs
allow you to check the input condition of the pulse.

Green: Pulses are being received.
Red: The input voltage range has
been exceeded.
Off: Pulses are not being received.
Note
• The LEDs on the frequency module illuminates 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 waveform acquisition of the
DL850/DL850V.
• When the preset of the frequency module is set to EM Pickup (electromagnetic pickup), the LED will not
illuminate in red when the range is exceeded.
For information about presets, see section 1.7, “Configuring Frequency, Revolution, Period, Duty Cycle,
Power Supply Frequency, Pulse Width, Pulse Integration, and Velocity Measurements,” in the user’s
manual.
