  5. To scroll through the register numbers use the arrow buttons
  6. To change the value in the register, press the enter button.
    1. The Hex and Dec values begin to blink.
    2. Use the arrow buttons to scroll through the numeric values.
  7. When you are finished making changes to that register, press the enter button to continue to the next register or press the menu button to save the changes.
Option Available Values
Reg List the register numbers.
Hex List the hexidecimal value of that register.
Dec List the decimal value of that register
*If you are viewing a scaled metered value, such as voltage, the circuit monitor updates the displayed value as the register contents change and scale factors are not taken into account in this view. This is the raw value with no scale factor applied. *
*NOTE: Some circuit monitor registers are read/write and some are read only. You can write to read/write registers only.
See the attached document for the original instruction release which also works for the CM3000 as well.
