Pulse LED display The small orange LED above the LCD display flashes according tothe pulse frequency set (1 Hz: once per second; 2 Hz: twice persecond) when current is flowing through the electrodes. At thesame time, a louder tick can be heard. The LCD display According to the display mode selected,...
Page 11 - The tone; Initial set up, maintenance, and general advice; Testing the Stimuplex
The tone 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, thentaking into account the measuring tolerance (see page ...
