AC POWER SUPPLY/BATTERY POWER
The meter may be powered the following ways:
Batteries only
Typical operating time when using the three (3) each
AA alkaline batteries only:
Up to 1 year in display mode only, no data logging,
no alarms.
Up to 1 month with data logging on at a 1 minute
recording rate, with no alarms. Higher capacity
memory cards require more power to operate;
therefore, larger cards will exhaust the batteries
more rapidly.
AC power supply only
If the AC power supply is being used without
batteries, in the event of a power outage, the meter
will turn off and data logging will stop.
AC power supply and batteries together
Using the AC power supply and batteries together
allows the batteries to act as a backup power supply
in the event of a power outage.
When using the AC power supply and batteries
together, the batteries will need to be replaced
periodically to insure they have suf cient power to
operate the meter during a power outage (see the
“Battery Replacement” section).

ALARM SOUNDING
With an alarm enabled, when a reading being
measured is outside the alarm limit that has been
set (equal to or lower than the low alarm set point, or
equal to or greater than the high alarm set point):
  will  ash on the display next to the
measurement that is alarming (ambient
temperature, ambient relative humidity or probe
temperature).  will continue to  ash next to the
measurement until the measured value returns to
an in-range condition.
The red LED will  ash continuously for the  rst 10
seconds, and will then  ash every 10 seconds
until the measured value returns to an in-range
