All the TensCare devices (except TENSOne and Flexistim IFT and Microcurrent modes, because of technical differences) are designed so that if they are not correctly connected to your body, the strength in the channel which is not properly connected will automatically reset to zero.

(Perfect Mama has only one intensity control, so must have all four pads connected)

This is to prevent sudden changes if a broken connection is re-made.

The current has to go through one branch of the lead, through the electrode pad, through the skin, and back down the other branch. If there is a fault in the lead, plug/socket, or machine, or pad connection, then the stimulation will stop.

If you have set the intensity quite high to compensate for Accommodation (reducing sensation), then sensation will gradually return as the effect wears off.

A movement could then re-make the connection with broken lead or pad, returning the intensity to the high setting you had selected. This sudden change can feel like an "electric shock" and be quite unpleasant.

The Open Circuit Cutout feature prevents this.

If you cannot increase the Intensity above zero:

  • You must be connected with two pads for each lead you are using (some devices use only one lead.)
  • Check that the electrode pad is sticking firmly, and not starting to peel off. If is, try dampening the surface with a drop of water and pressing the pad firmly onto your skin. Wait 1 or 2 minutes for the gel to warm up and improve its connections
  • Check that the lead is plugged in to the socket of the channel that you are using.
  • If it still doesnt work, try swapping the leads. If this corrects the problem on this channel, then you need to buy a replacement lead.

Hi I recently ordered this from amazon but it has never worked. It won’t let me increase the intensity?



Dear Holly,

Recent testing has confirmed our probes do not contain nickel, so you do not need to worry about nickel allergies.

We will continue to sell our gold probe as an alternative for those who suffer from particularly sensitive skin, however most users will be able to use our standard probes without issue.

Placing anything between the probe/electrode and the skin will block the stimulation, meaning the device will not work, so you should use the probe uncovered with the addition of a water based lubricant if you so wish.

I hope this helps, if you have any further questions please feel free to reach out to where one of our friendly customer service team will be happy to assist you.



It seems that many of us may have nickel allergies. Would it help to put some type of thin cover over the probe (eg. a condom or something else)? to cover the silver contact?
