Hand-held Analyzer Types 2250 and 2270 – User Manual

4.4.5 Use of Stylus and Navigation Pushbuttons

The stylus and navigation pushbuttons are used for setting up the analyzer, navigating through

the screens and managing the results.

A number of items that appear on the screen (parameter values or icons) can be selected,

updated and activated. For instance, a new parameter value can be selected from a drop-down

list.

The selection and activation of items on the screen can be done in two ways:

• Tapping once on the item on the screen will select and activate it, or

• Moving the field selector around using the navigation keys until the item you want is

highlighted, then pressing the Accept pushbutton to activate it

You can choose to use the stylus or the pushbuttons, depending on your preference and the

measurement situation. For instance, if the amount of noise generated by the analyzer needs to

be kept to an absolute minimum, consider using the pushbuttons rather than the stylus – this is

because tapping of the stylus on the touch-sensitive screen may create extra noise. However, if

speed is of major importance, the stylus can navigate through the setup and measurement

screens quicker.

Throughout the manual we have described how to perform the measurement procedures using

the stylus only, but you may also use the alternative method (using the Navigation and Accept

pushbuttons) if you prefer.

4.4.6 How to Change Parameter Values

Most parameter values are changed by selecting a new value from a drop-down list, which

appears when the parameter field is selected. See the example in Fig.4.3.
