2.6 Connecting the Logic Probe
______________________________________________________________
WARNING
The ground sides of the logic inputs are connected in
common to the frame ground of the product. Therefore,
if the product is powered by the AC adapter and the
object to be measured is powered from a different
power source, the possibility exists for electric shock
or damage to the equipment. Furthermore, even when
power is supplied from the same source, a potential
difference can exist due to different ground-side wiring,
resulting in current flow through the logic probes that
could result in electric shock or damage.
To avoid these hazards, before connecting a logic
probe to the product and the object to be measured,
confirm that power is supplied from the same
grounded outlet using 3-wire grounded power cords.
Do not connect logic probes other than supplied by
HIOKI to the logic inputs.

NOTE
If no logic probe is connected, the corresponding logic
waveform is displayed on the screen at high level.
Carefully read the instruction manual supplied with the 9320-01
or 9321-01 LOGIC PROBE.
2.6 Connecting the Logic Probe
The logic input is located on the
top side of the product. Since one
logic probe can record 4 channels,
the combined maximum recording
capability for logic waveforms is 8
channels.
