(Page 95).
LCD Fast Mode (4.9.)
Note
• LCD Fast Mode takes effect only after 30 minutes of inactivity. (Each time the device is
powered up, a further 30 minutes of inactivity is required.)
• LCD Fast Mode affects Measurement mode only; it has no effect on Navigation mode.
Enables a faster rate of measurement from the device by disabling most of the display area.
Only the bar graph will be refreshed when LCD Fast Mode is set to ON.
Values
LCD Contrast (4.10.)
The factory setting is for optimum visibility at room temperature and in average light
conditions. Extremes of temperature will lessen the contrast.
Values
Adjust the value to improve visibility at room temperature and in average light conditions.
Change the value in small steps to ensure you can continue to read the display.
Secondary Value (4.11.)
Use the secondary value to capture the menu navigation path to any viewable parameter.
Once the navigation path is stored, the value of that parameter will be displayed in
Measurement mode as the secondary value.
While in Parameter View of the current parameter [see Parameter View under LCD Display
(Page 48)], press the decimal point key. This stores the path to the current parameter in the
Secondary Value, and displays the value for that parameter on the LCD display when in
Measurement mode. See The LCD Display (Page 48) for an illustration.
Simulate Enable (4.12.)
Replaces a physical jumper switch found on some FF devices to enable simulation when set
to ON. (Available only via LUI.)
Options
For more information on Simulation, see Simulation (Input) under Operation (LTB) (Page 75)
in AMS Device Manager. [See also Simulation under How the AIFB works in manual
