When alarms have been activated and one of the alarm set-points has been exceeded while logging
(once, at least), or when battery is low, the ALARM red LED will also flash every 8 seconds. To
check if the alarm indication is due to a low battery, press the BATTERY TEST key: the instru-
ment will make a sequence of four green flashes if battery is charged (LOG LED) and of four red
