Press Next / Prev button to switch the Channel  

Note: The unit shall measure the impedance of each channel, creating the high and low limits automatically. Whenever the 

measured impedance falls outside the limits, the channel shall be considered faulty. The limits are typically 15%, eg if the 

circuit has impedance of 1K 

Ω, the limits generated shall be 850 to 1.15K Ω.
