Check Value Menu Parameters

Pressing OK will initiate the current test using the
How to change parameters:
indicated parameter values.
Pressing the Down and Up buttons may be used to review and/or modify the parameter
values. The 'current' parameter, if any, is indicated by a > symbol. If there is no > symbol
present, pressing OK will initiate the current test using the indicated parameter values.
Parameters may be integers, floats, neumonics or strings. Pressing i with a > symbol
present, but not blinking, will provide a description of the indicated parameter.
Pressing OK with a > symbol present will 'open' the indicated parameter for modification
(it begins blinking).
Pressing i with a parameter 'open' will provide a description of the parameter
modification process.
Pressing Cancel with a > symbol present, but not blinking, will reset the indicated
parameter to its default value.
While a parameter is selected (blinking) the value may be modified. Modifications are
restricted so that the value stays within the minimum and maximum limits for the
parameter. Button presses are ignored if the resulting value would violate the limits.
The value may be modified on a per character basis. The initial
Integer Parameters:
character selected is the least significant character. For the most significant character,
pressing Up or Down will change the selected character in the respective direction around
the following ring;
[ 0 1 2 3 4 5 6 7 8 9 + -]. The selection will not advance if the new selection would cause
the value to be out of range. For other than the most significant characters, the + and -
characters are not included. Pressing Back or Cancel buttons moves the character selection
within the parameter. If the current selection is the most significant character, pressing the
Back button will add a leading 0 to the parameter. The number of leading 0's is limited to
the remaining space on the display line.
Modification behavior is the same as for integer
Floating Point Parameters:
parameters except that a decimal point may be specified at any digit postion. Multiple
decimal points will cause value errors. Exponent notation is not supported.
Pressing Up or Down will cycle through a ring of the
Neumonic Parameters:
available selections. The Back and Cancel buttons are ignored.
The string may be modified on a per character basis. The initial
String Parameters:
character selected is the right most character. Pressing the Up or Down buttons will
change the selected character. Pressing Back or Cancel moves the character selection
within the string. If the curent selection is the most significant character, pressing the Back
button will add a leading <SP> to the string if the string is less than the maximum length
(defined for each string).
When a number is saved, any leading 0 is discarded. When a string is saved, any leading
space is discarded, this allows the deletion of undesired right most characters.
