When Neutral plate cable is single lined
while using the single pad mode
When connecting 'Single Pad' while using
the dual pad mode
When the contact area is small while using
the dual pad mode
2 "ALr 2"
When the cable is disconnected or short
while using the dual pad mode
During the use of dual pad mode, more
than 20% of the originally attached sheet
is fallen off over 20.
- 'DRM Setting Lamp' and 'Return Fault Indicator' start to flicker and alarm tone sounds,
cutting off the output.
※ Alarm condition
- Eight or more lights are on and alarm tone sounds.
: Short circuit is generated between cables.
- 3～8 lights are on and alarm tone sounds.
: Pad contact area decreased 80% smaller than the initial area.
: HF current from surgical unit has deteriorated pad adhesives during long time
operation.
: In this case, Patch the pad to the patient and press 'DRM Setting Switch' to
continue to operate.
- One or two lights are on and alarm tone sounds.
: Return Electrode is dismounted from the device.
: Cable of Return Electrode is broken.
: Pad is detached from the patient.
: Pad is taken out from clamp.
5) Relation between the light count of Assist Resistance Indicator and pad resistance
- The following table shows the resistance at the both ends of pad foil when dual pad is
sticked to the patient.
- In general, 6～8 lights are on in case of new dual pad. If four or less lights are on even
though the pad is completely sticked to the patient, it is necessary to replace the pad
with a new one. The more the lights are on, the higher the conductivity degree of pad
becomes. The high conductivity of pad secures safety of operations by reducing
output loss.
- The wider the pad area sticked to the patient becomes, the smaller the resistance
becomes.
Replace the single lined
cable.
Use the 'Dual Pad'.
Apply 'Dual Pad' to secure
larger contact area.
Replace the disconnected or
short line.
Re-attach the peeled-off Dual
Pad, or Replace with a new
Dual Pad.
