2.3) Proximity Indicator
This is only relevant for Locating Mode
The proximity indicator notifies the user that the target charge range has been reached.
This function allows the user to set up an upper and lower limit of charge. When
contraction is elicited at the set charge, this indicator should indicate to the user that the
needle has reached the desired proximity to the nerve. This proximity is indicated both
visually and audibly.
Visual Indication:
•
Visually indicated in the diagnostics screen by two arrowheads.
•
Arrowhead indicating the lower threshold points upwards.
•
Arrowhead indicating the upper threshold points downwards.
•
The dotted line representing the selected current will be positioned between the two
arrowheads if the target charge range is entered.
Audible Indication:
•
A successful stimulus above the proximity range will make a single beep.
•
A successful stimulus within the proximity range will make a double beep.
•
A successful stimulus below the proximity range will make a triple beep.
