5–20

Advanced Operation primary winding inductance of 100mH ±0.5% and a Q factor greater than 0.5 would be sorted into bin 2.

Figure 5-19 is an alternative set-up with stacked limits, sorting the transformers by absolute value. In this case, a transformer with a primary winding inductance of 112mH and a Q factor greater than 0.5 would be sorted into bin 3.

5.9.1.1 BINNING MODE – Set Parameters

Parameters which are common to IMPEDANCE MODE are described in section 4.7.2—

IMPEDANCE MODE Parameters.

Reset

Resets all bin limits to 0 after displaying a warning message, shown in

Figure 5-20 below. Confirm by pressing the Yes soft key. Absolute and percentage limits must be reset separately, but since the minor term is common to both, it is reset from either limits mode.

Series/Parallel

Abs %

Nominal

Only available for tests of: L + Q (Pri), L + R (Pri), C + D (Pri), and L + R (Sec). Selects series or parallel equivalent circuit for measurement of the selected parameters.

Toggles between Abs and %. When Abs is selected, absolute Hi and Lo limits (i.e. units of the measured parameter) are displayed.

When % is selected, a nominal value together with Hi and Lo percentage limits are displayed.

The limits and nominal value must be set using the navigation keys to highlight each parameter, and the data entry keypad to set each value (the use of the data entry keypad is described in section

4.2.6). When in % mode, the Hi and Lo limits can be set equidistant about the nominal by setting either of the limits then highlighting the other limit and pressing the keypad Enter key twice. This mimics the setting of the first limit but with the opposite sign.

This soft key operates only when percentage limits are displayed.

The nominal value is displayed below the percentage limits and can be seen, set to 100mH, in Figure 5-18. The nominal is set by pressing the Nominal soft key and entering the value using the data entry keypad.
