The 8826 has separate inputs for eight probes, but the ground lines of
these inputs are not isolated from each other and from the frame ground
of the unit (common ground). If voltage having a different ground level
is input, a short circuit will occur, depending on the probe type.
Do not connect logic probes other than supplied by HIOKI to the logic
inputs.

9.1 Logic Inputs
■ Logic Probe Connection
・The logic input is located on the top side of the unit. Up to eight probes can
be connected.
・Since one logic probe can record 4 channels, the combined maximum
recording capability for logic waveforms is 32 channels.
・Connect the probe by aligning the groove on the plug with the ridge on the
connector.
・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 probe.
