SET DATE allows the current date to be set. In the M&C shell, the
format is MMDDYYYY and al fields must be set.
SET TIME allows the current time to be set. In the M&C shell, the format
is HHMMSS and all fields must be set. The time is in 24-hour format.
RESTORE ROM DEFAULTS – WARNING: This will erase user and factory
calibration settings!
Selecting YES and pressing ENTER restores all DTR parameters to factory
ROM defaults. The DTR will reset.
FORCE CLEAR FAULTS forces the system to clear all faults. Faults which
are set periodically will appear again. Also see ACKNOWLEDGE FAULTS
below.
4.2.5.6 INTERFACE OPTIONS
LCD CONTRAST adjusts the contrast of the LCD display. Choose a value
between 0 (for least contrast) and 30 (for most contrast). The default value
is 6.
LOW LEVEL SIGNAL – This value, in dB, sets the trigger threshold for the
LOW INPUT SIGNAL fault. Regardless of this value, the LOW INPUT
SIGNAL fault will still occur if input signal is undetectable. The default value
is -120 dBm.
LOW SIGNAL ALARM – LOW SIGNAL ALARM enables the LOW INPUT
SIGNAL alarm, allowing the fault to be reported. This is not useful for most
applications and is disabled by default.
HIGH TEMP LIMIT – This value, in degrees Fahrenheit, is used to trigger the
TEMPERATURE ALARM fault. The default value is 120 F.
4.2.6 ACKNOWLEDGE FAULTS
Choosing [ACKNOWLEDGE FAULTS] clears current alarm conditions. The fault
messages remain displayed on the screen, but no longer cause an alarm and the
summary fault contact closure is no longer asserted by the faults. Also see FORCE
CLEAR FAULTS.
