Chapter 2 Malfunction? First, Investigate.
Corrective Action to be Taken in Case of an Abnormality
If maintenance service is required, or if the instrument still does not operate
properly even after proper corrective action has been taken, contact your
nearest YOKOGAWA representatives listed on the back cover of this manual.
Symptom
Possible Cause
Corrective Action
Cannot make DC measurements
(or at low frequencies up to few
hundred Hertz) or the amplitude
is small in the given frequency
region.
Power is not turned ON.
Turn ON the power.
The measurement instrument,
such as an oscilloscope, is set
to AC coupling.
Set the instrument to DC
coupling.
The sensor is not locked
(it is not hooked securely).
Lock the sensor.
Cannot adjust to the zero level
using the zero adjustment dial.
The sensor is magnetized.
Demagnetize the sensor
before adjusting the zero level.
The amplitude is small across
all frequencies.
The input impedance of the
measurement instrument,
such as an oscilloscope, is
set to 50
Ω.
Set it to 1 MΩ.
