6. Interface Spring Pins
When the probe interface is connected, it touches the pad on the interface
board of the oscilloscope. The probe's power and offset voltage are supplied
through this interface component. It also automatically recognizes the probe
type.
7. Latch Release Lever
Release the lock when connecting the probe interface to the oscilloscope
input.
If the waveform measuring instrument to be connected to the output
terminal (BNC) of this probe has other measuring terminals, the probe's
connection terminals and internal circuits may become hazardous live
depending on the types of devices that are connected to the instrument's
measuring terminals.
To avoid this, note the following:
• Ensure that basic insulation equivalent to that of the circuit under
measurement in terms of measurement category, operational voltage,
and pollution degree is used between the measuring terminal to which
the probe is connected and other measuring terminals.
• If the basic insulation across measuring terminals does not meet this
requirement, do not apply an input exceeding the safety voltage level to
any of the other measuring terminals.
• Always ground the measuring instrument.
• Take care to avoid electric shock whenever connecting the probe
to a measuring terminal. Also, never disconnect the probe from the
measuring instrument while the probe is connected to the circuit under
measurement.
• Before connecting the probe to the circuit under measurement, confirm
that the measuring instrument is correctly grounded, and that the probe
interface is properly connected to the measuring instrument's input.
• Make sure to read all safety precautions and warnings such as
information concerning electric shock for any instruments to which the
probe will be connected.
• Do not short-circuit between the two measurement lines with the metal
part of the sensor unit. It may lead to a serious accident such as the
occurrence of an arc.
To clean the instrument, wipe using a soft cloth with a small amount of
water or mild detergent. Never use detergents that contain benzine,
alcohol, acetone, ethyl compounds, ketones, thinner, or gasoline as
deformation or discoloration can result.
