Usage Notes
CAUTION
• When connecting an input connector other than
a BNC connector, for example a conversion
plug, do so such that the BNC center conductor
is positive and other metallic parts are ground
potential (or negative).
Reference
• Device output is terminated internally. Since the output
resistance is 50
Ω
, the device must be used with a
waveform measurement instrument (oscilloscope,
recorder, etc.) that has an input impedance of at least
1 M
Ω
. Accurate measurement is not possible with
waveform measurement instruments that have an input
resistance of 50
Ω
.
• An AC voltage waveform may appear in the output
under certain circumstances, even under conditions
of no input, if the device is connected to the 3269 or
the 3272 Power Supply while the power supply is on.
This does not indicate a malfunction. The AC voltage
waveform that appeared in the output will disappear,
and operation restored to normal by opening and closing
the sensor head.
