• Last error code: 0 = no errors
An error causes a 3-digit error code to appear on the display. The
first digit indicates the command number, while the remaining two
digits indicate the parameter where the error occurred (i.e. first
parameter is indicated by 01, second indicated by 02, and so on).
• Auto-ID resistance value (Ω) for CH1, CH2, CH3, and SONIC
A reading in the vicinity of 999 kΩ indicates that the applicable
channel is open.
• List of all active channels (Variable)
0 to 1023
Calculation Method:
(See circuit diagram)
1023(bit)×R÷(R+10(kΩ))
