3.4 Connecting the Probe
Connect a probe (or measurement input cable such as a BNC cable) to the input terminal on the
bottom of the front panel. The input impedance is 1 M
Ω
± 1% and approximately 20 pF in parallel, or
50
Ω
± 1.5%.
WARNING
• Always turn off the power of the object to be measured when connecting it to this
instrument. Connecting or disconnecting a measuring lead while the power of the object to
be measured is on is extremely dangerous
• Do not input excessive voltages that exceed maximum input v
oltage, withstand voltage, or
tolerance surge voltage.
• Always use a protect ground (earth) for the instrument to prev
ent electric shocks.
• Avoid continuous connections in environments where there is the possibility that tolerance
surge voltages can be generated.
CAUTION
• The probe interface terminal is located near the input terminal on this instrument. When
connecting the probe, make sure to prevent an excessive voltage due to static electricity,
etc., from being applied to the probe interface terminal, as this may damage it.
• The probe interface terminal is located near the input terminal
on this instrument. Do not
short the probe interface terminal.
• The maximum input voltage for 1 M
Ω
input is 150 Vrms when the frequency is 1 kHz or
less. Applying a voltage exceeding the value can damage the input section. If the frequency
is above 1 kHz, damage may occur even when the voltage is below the value.
• The maximum input voltage for 50
Ω
input is 5 Vrms and 10 Vpeak. Applying a voltage
exceeding either of these values can damage the input section.
Precautions to Be Taken When Connecting Cables
• When connecting a probe to the instrument for the first time, perform phase correction of the probe
as described in section 3.5, “Compensating the Probe (Phase Correction).” If you do not, frequency
characteristics will not be flat, and measurements will not be correct. Perform the phase correction
on each channel to which a probe is to be connected.
• Note that if the object being measured is directly connected to
the instrument without using a
probe, correct measurements may not be possible because of the effect of input impedance on the
instrument. Use caution.
