Enter a floating-point value using exponential notation
Exponential notation is used to enter values that are larger than 99999999 or smaller than
−9999999.
Exponential values entered via the display must be in the following form: SX.XXXEYY. In
this string:
• S = Sign. A minus sign (−) indicates a negative number. A blank indicates a positive
number.
• X.XXX = The 4-digit mantissa.
• E = The exponent indicator.
• YY = The 2-digit exponent.
Procedure

Switch from decimal notation to exponential notation.
a. Activate Select as required until the rightmost digit is flashing.
b. Activate Scroll until E is displayed.
c. Activate Select.
Tip
If you have modified the value in decimal notation without saving the changes to transmitter
memory, the changes will be lost when you switch to exponential notation. Save the decimal
value before switching to exponential notation.
2. Enter the exponent.
The first character may be a minus sign or any digit between 0 and 3. The second
