5.6.1 Detection of a high resistance in the patient circuit
In the case, when at the start or during an electrotherapy / combined therapy treatment procedure, the device
detects a state of high resistance in the patient circuit, which may be caused by:
• incorrect connection of electrodes,
• a poor contact between electrodes and tissue (e.g. viscose pads are not moistened enough),
• worn electrodes,
• damaged interconnection cables,
the information about a probable cause of the problem will be shown on the display.
The detection system of a high resistance in the patient circuit is active during the treatment procedure. The
detection system works when current value is more than 2,5 mA or voltage is set above 15 V.
Detailed description of cables and electrodes condition control is given in chapter 10.4.
Depending on the conditions of a high resistance detected in the patient circuit, the device displays the messages
that are shown in Figure 5.6.
