operating mode (Twitch, TO4, DBS or Tetanus) that flashes when
a stimulus pulse is delivered. Each flash of the pulse indicator is
accompanied by an audible chirp.
The stimulus pulse indicator will not flash if the unit is in an open
lead condition or paused. If the mode is changed when the unit is
paused, the static waveform changes to represent the new mode.
This field is blank only when the unit is in the null mode.
Error Codes: When the unit detects either current leakage or a software
error, it will cease operation and the LCD will display the appropriate fault
code (flashing every 0.5 seconds) until the user turns the unit off.
If either Er1 or Er2 is displayed, the device is defective. Discontinue
using the ES500. Refer to Section 8.0 - Limited Warranty.
If Er3 ( low battery) is displayed, turn the unit off and replace the battery.
Er1: Leakage Current detected
Er2: Software Error detected
Er3: Low Battery detected
