Hanna Instruments HI 98811 - Manual (Page 4)

4
To prolong battery life, the backlight and printing features are
disabled when the batteries are getting low; "LOBAT" indication is
displayed on LCD to warn the user of this condition. However, the
meter continues to measure correctly even when the low battery
indication is displayed. The meter automatically switches itself off
when the batteries are too weak to support proper function.
The meter is equipped with an internal lithium battery that powers
the clock circuit even in the absence of power supplies.
For long term field and lab applications, this meter can be connected to
a 12VDC adapter.
HI 98811 has the capability to store the measurements in memory at
a user selectable interval from 1 to 180 minutes. This information can
be retrieved at a later time and also printed.
Each measurement/lot can be uniquely identified by assigning a
sample ID code obtained by reading from a Dallas i-Button
® tag
(DS1990A, etc) suitable placed in the field.
HI 98811 also allows the transfer of stored data to a computer via
the HI9200 infrared transmitter connected to the computer RS232
port.
Each meter can also be uniquely identified by the user by assigning
an instrument ID code.
