7.3.4 MAN-DOWN ALARM
The Man-Down Alarm, when enabled, warns nearby personnel if the instrument remains motionless for
a pre-set time. If the instrument is fitted with the wireless modem option and connected to a network, it
sends alarm notifications to the command centre, enabling a rescue operation.
You can change various properties of the man-down alarm:
• You can turn the man-down alarm on or off.
• You can set the motionless time after which the instrument warns that it is
going to activate the man-down alarms.
• You can set the warning time. During the warning time, the user can prevent
the alarms from activating.
• You can set the sensitivity. High sensitivity means small movements are
enough to prevent the man-down alarm from activating.

7.4 DATALOG

The instrument automatically stores the detected concentrations at a pre-set time
interval. In the readout screen, the datalog icon shows that data is logged.
Data is stored in non-volatile memory for download to a PC. The data is retained,
even when the instrument is turned off or the battery is removed. Data is
organised in events, with a new event created each time the instrument is turned
on, a configuration parameter is changed or datalogging is interrupted. Every
event includes User ID, Site ID, serial number, last calibration date and the alarm
limits.
Notes
• You cannot turn off the datalog function.
• By default, the instrument stores the detected concentration every 60 seconds.
In the datalog submenu, you can adjust the interval and clear all logged data.
