The 4263B’s transformer measurement function enables the measurement of the N, M, L1 and the

DC resistance of the primary by changing measurement circuit connections with an internal switch.

Figure 5-20 shows a simplified schematic block diagram of the 4263B.

A test signal is applied to the primary and, L1 is calculated from the measured values of V1 and I1.

M is calculated from V2 and I1. N is obtained from the ratio of V1 and V2.

In the DC resistance measurement, the applied voltage at the Hcur terminal is DC. DC resistance

value is calculated from measured DC voltage V1 and current I1.

Using the 16060A transformer test fixture with the 4263B permits L2 and DC resistance measure-

ment for the secondary along with all the parameters for the primary. The circuit connection dia-

gram of the 16060A is shown in Figure 5-21.
