• 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))
