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.)
9199
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.

! DANGER
Option
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.
