D [Sel]
The [Sel] key is used to enable an entry field for input by the user. When the [Sel]
key is pressed, the field is highlighted in white and a number of underscores are
used to indicate the maximum length of permissible entry. Pressing this key when
a field in a dialog has been selected for user input will result in entry of the number
“2” or the entry of the letter “t, u, v’ if the field is non-numeric.
E wxyz
A number and a series of letters appear beneath most of the keys on the numeric
keypad. These can be used when an entry field has been selected for user input
using the [Sel] key. Refer to the example of text input later in this chapter.
F [+/-]
Used to enter a “+” or “-“ symbol in a numerical entry field.
G Decimal point
Used to enter a decimal point in certain fields for numeric entry.
H [Clr] / Local
The [Clr] key is used in a user entry field to delete the letter or number that was
last entered. It is also used to revert the unit from remote to local operation.
I [On/Standby]
Used to turn the power meter on and off once the main AC power has been
supplied.
