Easily monitor leak current fluctuations
In combination with a HIOKI MEMORY HiCORDER this unit can be used for unattended monitoring for leak current condition.
Example for a monitoring system using the 3283 and 8807 MEMORY HiCORDER
The
3283
can supply a
REC
signal
(recording signal, 1V DC/f.s.)
or a
MON
signal
(waveform signal, 1V AC/f.s.)
. The
9094
OUTPUT CABLE
(option) or conversion
9199 BNC TO
BANANA ADAPTER
(option) can be used for connection to
the
8807.
For monitoring of instantaneous leak current
waveforms, set the output to
MON,
and select a suitable trigger
level in the memory mode of the
8807.
This will cause
recording to be performed only when leak current is detected.
The trigger output terminal (open collector output) can be used
as an alarm output. For long-term monitoring, the
8807
should
be powered from the
9418-10 AC ADAPTER
and the
3283
from the
9445-02 AC ADAPTER
.
Setting example for 3283 and 8807
When leak current exceeds 20 mA, the trigger is activated and recording is carried
out, extending also to data before triggering occurred. The
3283
is set to the 100
mA range, and the output is set to
MON.

WARNING
Inspect the unit and check that it is operating correctly before use. When carrying out
measurement on live lines, wear proper protective gear, insulating rubber gloves, insulating
rubber boots and safety helmet, and use extreme caution to avoid electric shock accidents.

DANGER
1. In order to prevent short-circuits and injury, use the clamp product on electrical
circuits with a voltage less than the maximum operation circuit voltage.
2. In order to prevent short-circuits and injury when the clamp core tip is open, do
not use bare conductors.
