The Battery Error Preventing System (BEPS) recognizes batteries levels
as they become weaker.
To prolong battery life, the backlight and printing features are dis-
abled when the batteries are getting low; "LOBAT" indication is displayed
on LCD to warn the user of this condition. However, the meter contin-
ues to measure correctly even when the low battery indication is
displayed. The meter automatically switches itself off when the batter-
ies are too weak to support proper function.
The meters are 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, these meters can be connected
to a 12VDC adapter.
HI98801 and HI98804 have 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.
HI98801 and HI98804 also allow the transfer of stored data to a
computer via the HI9200 infrared transmitter connected to the com-
puter RS232 port.
Each meter can also be uniquely identified by the user by assigning an
ID code.
