EVENT LOG AND TIME & DATE
An event log function is available that allows one to view certain events (danger and critical alarm) that occurred.
Up to 250 events are stored.
To view the log, from the main operating screen, press any push button and then LOG.
LOG MENU SELECTIONS
VIEW Access the event log selection menu.
TIME View and possibly change the time and date. Also, the power up timer (hour-
meter) is under this selection.
ESC
Go back to the main screen.
CH1 View the event log for channel one
CH2 View the event log for channel two (if enabled).
ESC Go back to the main screen.
While viewing the event log screens, there is no push button legend, so the push
buttons operate as follows (left to right): NEXT, LAST, (no function) & ESC. This is
consistent with the other screens. See the text box to the right; the top two lines
are displayed and the bottom line (not displayed) shows the push button
assignments.
The instrument logs danger and critical alarms (whichever occurs). The average gas exposure (AVG in ppm or
mg/l), maximum gas exposure (MAX in ppm or mg/l) and duration the alarm condition occurred (Ti) are logged after
the event no longer exists. The time is displayed as hours, minutes, and seconds (HH:MM:SS); the maximum time
duration (Ti) is 99:59:59.
SENDING THE EVENT LOG TO A REMOTE SYSTEM (COMPUTER)
Serial command EVL will send the following information to a computer RS-232/RS-485 port. The channel number is
specified (1 or 2). A header is sent, which contains the channel number and gas sensor type.
The data sent is the date and time of the event, event type (DGR or CRT), maximum (peak) exposure (in ppm/mgl
units), average exposure (in ppm/mgl units), and the duration (time in hours:minutes:seconds) of the event. Up to
250 events are logged, and when the log memory is full, the oldest event is replaced by the latest event. See the
serial command section of this manual for more information.
CLEARING THE EVENT LOG
The event log cannot be cleared from the front panel. There is a serial command that will clear the event log
(EVLCLR). See the serial command section of this manual for more information.
TIME MENU SELECTIONS
View and set the internal clock.One can set the time and date by pressing SET.
Screen time-out is thirty-seconds (returns to main screen).
HOUR METER
Displays the hours:minutes that the monitor has been powered. This counter
cannot be reset and is maintained by a capacitor-backed memory and EEPROM
when the monitor is powered down. Screen time-out is thirty-seconds (returns to
main screen). This counter cannot be reset.
