2-3-4. SELECTING DISPLAY FORMATS
You can select from four 4278A display formats. To observe the available display formats,
confirm that softkey page 3/4 is displayed in the lower-right hand corner of the LCD, and
perform the following procedure.
1. Press the `DISPLY PAGE' softkey, and the four available format selections will be
displayed.
2. Press the 'SORT PAGE' softkey. This format displays bin sorting results.
3. Press the TRIGGER key and observe the display. The bin number selected and the
capacitance and conductance measurement values for the capacitance measure-
ment you just performed will be displayed.
4. Press the 'LIMIT PAGE' softkey, and the Limit Table will be displayed. From this
format, you can establish comparator limits, as explained in paragraph 2-3-3 (the
preceding procedure).
5. Press the 'return', `COMPARATOR', and 'COUNT' softkeys.
6. Press the `COUNT ON' softkey. Observe the COUNT column (right-most column) of
the Limit Table, and perform a measurement by pressing the TRIGGER key. The
count number for the bin a capacitor is sorted to, depending on measurement re-
sults, will increase by one for each measurement performed. This allows you to
keep track of how many capacitors are sorted to each bin.
7. Press the 'RESET COUNT' softkey. Note that all bin counts are reset to zero.
8. Press the 'return' softkey twice, then press the 'DISPLAY PAGE' softkey.
9. Press the 'STATUS PAGE' softkey and observe the display. This page displays the
present compensation data status.
10. Press the `MEAS PAGE' and `return' softkeys.
11. Press the 'DISPLY CONTRL' softkey.
12. Press the 'No. of DIGIT' softkey. This page allows you to select the number of dis-
play digits, and, therefore, displayed measurement resolution. Press the TRIGGER
key and note that measurement results are displayed to six digits. You can control
the number of displayed digits by pressing the corresponding softkey.
13. Press the '6 DIGITS' and 'return' softkeys.
14. Press the 'DISPLY VALUE' softkey. Because MEAS VALUE is selected (default set-
ting), capacitance measurement values are displayed as Cp.
