Parameters to Configure
There are four parameters you can configure:
• NumberOfDecimals defines the number of decimal places displayed for the
Process Value, e.g. setting NumberOfDecimals to 3 will give a displayed
Process Value in the form 1.234.
• MinValue and MaxValue define the lower and upper limits respectively of the
acceptable range for the Process Value.
• Unit defines the engineering unit in which the Process Value is shown and
appears on the display.
Configuration Step-by-Step
The steps listed below describe how to enter the Configuration mode and set each
of these parameters in turn. As an example a Process Value within the range –20
to +120°C with two decimal places is used.
1 Press and hold the Next key.
2 If you are prompted to enter the password, press the Up and Down keys to
change the displayed number until it matches your password.
3 When the password is correct press the OK key.
