My apologies in advance for a newbie question.. For a typical AB safety relay with S11 to S12 for CH A, and S21 to S22 for CH B, what is the best way to check the safety circuit continuities? I think the best way is to first place the DC voltameter probes across S11 and S12. If there is 12V there, keep the probe on S11 and move the probe on the S12 back to each estop switch until reading 0 volt. Is there a better way? Thanks.
