Parameters
4.9. LCD Fast 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.
4.10. LCD Contrast
The factory setting is for optimum visibility at room temperature and in average light
conditions. Extremes of temperature will lessen the contrast.
Adjust the value to improve visibility in different temperatures and light conditions.
Change the value in small steps to ensure you can continue to read the display.
4.11. Memory Test
Allows verification of the RAM, EEPROM, and Flash memory of the SITRANS LR250.
• Press RIGHT arrow to edit then press any numeric key from 1 to 9 to activate the
test.
• The reading will display BUS and then the test result text.
Notes:
• 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.
