Time/Date Synchronization
The MC-III EXP includes a real-time clock for timekeeping and log time stamps. Upon connecting with
the instrument, the interface software prompts the user to synchronize the instrument time and date with
the time and date displayed on the computer if the time difference exceeds 60 seconds. To change the clock
synchronization threshold to a value other than 60 seconds, see General Options, page B-1.
A user can synchronize the instrument and computer clocks at any time by clicking the “Sync to Computer
Time” button on the System Setup screen.
Contract Hour
Hourly ow totals are logged in the archive on the hour. The contract hour determines the exact time when
the daily ow total is logged. The contract hour is easily adjusted by selecting the appropriate hour from the
dropdown list on the System Setup screen.
LCD Contrast Adjustment
LCD contrast is temperature-dependent and may require adjustment for optimum readout visibility. A slide
bar allows users to quickly adjust the contrast of the LCD.
