• Alarm - There is a severe problem causing the channel to
be out of action, and the system alarm relay to be enabled
• Warning - Events less critical than a system alarm (e.g.
measurement alarm)
• Information - For information only; no action is required
In addition to the above, if the RTC battery is running low and needs to be
changed, the icon illustrated left is displayed in the bottom right corner of the
numerical view screen.
If using a portable instrument, this icon blinks alternatively with the standard
battery icon.
