Appendix 6 Zero Adjustment

Appendix
To perform zero adjustment using measurement leads
When you actually perform zero adjustment using measurement leads, you may unexpect-
edly make the connection shown in Table 1 (b). Therefore, when performing zero adjust-
ment, you need to pay sufficient attention to the connection state of each terminal.
Here, L2101 Clip Type Lead is used as an example for the connection explanation. Table 2
shows the connection state of the tip of the lead and equivalent circuit in the respective cor-
rect and wrong connections. Table 1 (a) indicates the correct connection method, resulting
in 0 V between SENSE A and SENSE B. However, Table 1 (b) is the wrong connection
method, so that 0 V is not obtained between SENSE A and SENSE B.
