Each generated pulse produces a tick. When a stimulation current flows to the electrodes (greater than 2% of the maximum stimula- tion adjustable), the tick becomes louder.
If the stimulation current flowing exceeds the current set, then taking into account the measuring tolerance (see page 12 - Techni- cal data - Measuring tolerance), the Stimuplex® HNS 11 institutes an error message consisting of several tone groups of rapid frequency (approx. 6 Hz). The device is no longer operational.
Each time a button is pressed a short tone is produced of a differ- ent frequency as audible confirmation.
A click confirms that the instrument has been switched on.
Initial set up, maintenance, and general advice
Testing the Stimuplex® HNS 11 before an application
Switch on the Stimuplex® HNS 11 nerve stimulator by turning the control knob clockwise from position O. A short click confirms that switching on has taken place. When the
With the set current indication (mA 
), do not connect both elec- trodes - check both current ranges (1 mA max and 5 mA max) up to maximum.
Switch to actual current indication (mA
) - both mA ranges give a should reading of + 0.00 mA, independet from the set current.
Connect the two electrodes (clip and plug) together: check the mA value in each case up to the maximum. All mA values have a ”+” sign in front of the display. As soon as current flows, the LED above the display flashes in time with the stimulation current. The ~ symbol appears next to the ▲ and the tick becomes louder.
Set an actual current of approx. 0.30 mA and switch to set current (mA 
): the two values should be the same (see Page 12 - Techni- cal data - Measuring tolerance).
If all adjustments have been found to be correct, your Stimuplex®
HNS 11 is ready for application.
