HD2102 - 21 - V2.3
LOW BATTERY WARNING AND BATTERY REPLACEMENT
The battery symbol
on the display constantly shows the battery charge status. To the extent that batteries have
discharged, the symbol "empties". When the charge decreases still further it starts blinking…
In this case, batteries should be replaced as soon as possible.
If you continue to use it, the instrument can no longer ensure correct measurement. The memory
data are maintained.
If the battery charge level is insufficient, the following message appears when you turn the
instrument on:
BATT TOO LOW
CHNG NOW
The instrument issues a long beep and turns off. In this case, replace the batteries in order to
turn the instrument back on.
In order to avoid data loss, the logging session is ended, if the HD2102.2 is logging and battery
voltage falls below the minimum operating level.
The battery symbol turns off when the external power supply is connected.
To replace the batteries, switch the instrument off and unscrew the battery cover counter clockwise.
After replacing the batteries (4x1.5V alkaline batteries - type AA) screw the cover on clockwise.
After replacing the batteries, the date, time, baud rate, type of probe, printing interval, logging
parameters must be set again: in order to simplify the operation, on insertion of the new
batteries the instrument turns on automatically and requests these parameters in sequence.
