Model 2651A High Power System SourceMeter® Instrument Reference Manual
minimum and maximum can be used to limit the values that can be entered. When + is selected for format, the
minimum limit must be more than or equal to zero. When limits are used, the operator cannot enter values above
or below these limits.
The input value is limited to ±1e37.
After sending this command, script execution pauses for the operator to enter a value and press ENTER.
For positive and negative entry ("+" sign used for the value field and/or the exponent field), polarity of a non-zero
value or exponent can be toggled by positioning the cursor on the polarity sign and turning the navigation wheel
. Polarity will also toggle when using the navigation wheel
past zero. A zero value or exponent (for example, +00) is always positive and cannot be toggled to negative
polarity.
After exectuing this command and pressing the EXIT (LOCAL) key, the value returns nil.
Example
value = display.prompt("0.00", "V", "Input 0 to +2V", 0.5, 0, 2)
print(value)
The above command prompts the operator to enter a voltage value. The valid input range is 0 to +2.00, with a
default of 0.50:
0.50V
Input 0 to +2V
If the operator enters 0.70, the output is:
7.00000e-01
