positive electrode around. Your objective is to find the spot where the
minimum muscle contraction will cause the greater EMG response.
5. Turn on the unit by pressing the ON/OFF button. Place the unit on a desk
in its stand or hold the unit. Relax so that the microvolts reading is as low
as you can manage, ideally below 1uV.
6. Press SET and contract as high as you can for 3 seconds to adjust the
Threshold automatically (see next chapter for threshold automatic and
manual operation). The threshold level should match your current muscle
performance, so when you contract and then relax, the bargraph should go
the full scale up and down in accordance with your movements.
To start the programme, press the START/ESC button.
7.
Follow the audio and display prompts: relax as much as you can when you
hear single beep sound and the display shows arrow down. Contract as fast
and as much as you can when you hear double beep sound and the display
shows the arrow up.
To end the programme before it is complete, press the START/ESC but-
ton again or turn the unit off.
8. When you have finished, remove and replace the electrodes onto the
clear plastic film and reseal them in the plastic bag.
If you are using a VeriProbe, clean the probe and let it dry before
sealing it in its plastic bag.
9. Store the electrodes in a cool dry place, such as a fridge, which prolongs
the life of your electrodes.
