The needle on the meter should “spike” to the right, showing zero
resistance. Figure 6.12 shows the meter set to RX 1 KΩ, with the leads
crossed and the needle to the far right, indicating that there is no
resistance and that the meter is working properly. Figure 6.13 shows
testing the conductivity of the solder connections.
