The status function of each LED is as follows:
GREEN STATUS
LED OFF Logger is turned OFF or in Low Power Standby state*
LED Single-blink Logger is in Standby Mode (and not recording)
LED Double-blink Logger is in Record Mode
ORANGE STATUS
LED OFF Logger is not in an Overload condition
LED Single-blink One or more inputs are in an Overload condition
YELLOW STATUS
LED OFF No alarm has been seen on any input
LED Single-blink At least one channel has seen an alarm at least once
LED Double-blink At least one channel is currently in an alarm condition
RED STATUS
LED OFF No data in memory
LED Single-blink Memory is partially filled
LED Double-blink Memory is full
BLUE STATUS
LED OFF Battery voltage is above 1.8 volts
LED Single-blink Battery voltage is below 1.8 volts
*To determine whether the unit is OFF or in Low Power Standby state, press the PRESS
button for 0.5 seconds. If the LED blinks, it is not OFF.
Note: Overload occurs when any input is 10% above its input range. When
the battery voltage goes below 1.7 volts the instrument will shut down
(terminating the recording, if it is recording).
In the STANDBY and OFF modes, the logger retains recorded information
for transfer to a computer.
Both of these modes have low power states, which require very little
power from the battery. The LEDs will not blink at this time. By using these
low power states, the instrument can be programmed to start recording at
some time in the future without draining the batteries.
STANDBY mode:
•
The instrument enters the low power state if the
button is not pressed for one minute. It will remain in this state until
either the button is pressed or the internal clock reaches the start
time for a scheduled recording.
RECORD mode:
•
The instrument enters the low power state
between sample sets. The slower the storage rate, the greater the
portion of time the instrument is in the low power state. Thus, the
slower the storage rate, the longer the instrument can record.
