ESSENTIAL PERFORMANCE:

• The ES500 in Low Current Mode (LCM) shall deliver LCM ≤ 5.15 mA.
• The ES500 in High Current Mode (HCM) shall deliver HCM ≤ 84 mA
Caution: Use of the ES500 outside the specified
electromagnetic environment may degrade or lose the essential
performance due to electromagnetic disturbances. In result, the
ES500 may stop operating, restart during procedure, operate outside
the current range specified, or go into error mode.
NOTE: The unit is considered to be in a null mode when no stimulus
mode/pattern is selected in HIGH output range.
The LCD provides a real-time display of user-set functions and
battery status, as shown and described in detail in Section 2.C. In
addition to the visible LCD Output Stimulus Pulse Indicator, the unit
provides audible chirp/beep feedback.
The Stimulus Amplitude Control dial provides variable current control
• 0.05 to 5.0 mA in the LOW output range
• 0.05 to 80 mA in the HIGH output range
All other controls on the face of the unit are buttons. Depending
upon the output range in use, any of the available modes is activated
by pressing the button for that mode.
