To correct a data entry error:
1. Press the CLR key. This initializes the entry point either to a blank area
or the previous data.
2. Enter or reenter the entire numeric. If the CLR key is pressed at this time,
then the numeric entry is aborted, the display returns to the previous
display.
3. If an incorrect multiplier key is pressed, then simply press the correct
multiplier to overwrite the previously selected incorrect one. If no
multiplier is required, but one is inadvertently selected, then press this
multiplier a second time to clear it.
4. If the decimal point is inadvertently pressed, then press the decimal point
again in the correct position to override the previous entry.
The previous sequence for numeric entry is generally used throughout all
entry sequences. Where specific differences exist refer to the following
paragraphs for an explanation.
Direct Entry of Required Output Level
When the display shows the actual output level and status, the required output
level may be entered. Key in the numeric data followed by the required
multiplier (if desired), and the required units (the units key terminates the
entry). The following entries are examples of this procedure.
If the required output is a voltage or current, then the required numeric data is
entered (with a multiplier if desired) followed by the required V or A units
key.
