2. Ensure correct polarity, and push the battery in flush with the bottom board until the
connectors snap together on both sides.
3. Replace the battery compartment lid.
IMPORTANT NOTE:
DO NOT REMOVE THE BATTERY WITHOUT TURNING THE METER OFF FIRST.
BATTERY REMOVAL WHILE THE METER IS ON MAY CAUSE LOSS OF STORED
READINGS AND MAY CORRUPT THE STORAGE MEMORY. IF THIS OCCURS,
CERTAIN FUNCTIONS (SUCH AS STATISTICS, READING RECALL, ETC) WILL FAIL
AND LOCK UP THE METER. If the battery is removed by accident while the meter is
ON, and if the readings already stored are important, DO NOT store additional readings.
Turn the meter back on and perform a PC download. Beware that any readings stored
during the power cycle that included the battery removal WILL NOT be available and
CANNOT be recovered. Once the download is complete, perform a meter reset by
choosing “RESTORE DEFAULTS” in the Storage Menu. If a download is not necessary,
go directly to “RESTORE DEFAULTS”.
LOW BATTERY:
The meter features a battery status monitor, designed to warn the user as well as protect
measurement accuracy from impending battery failure conditions. The battery warning is
triggered by either continuous or temporary low voltage conditions. Visible (a battery
icon on the top right side of the display) and audible (buzzer warble) indicators
accompany a battery warning.
Once a permanent low battery condition is detected, all measurement functions are
disabled. Enough power remains for other menu functions, including a PC download,
although almost any user action at this time causes a low-battery warning to be
generated. The battery should be replaced immediately. If the battery reaches critical
levels, the meter will refuse to stay on at power-up.
This gradual warning system is intended to provide the user advanced battery status
notice and give ample time for replacement before operational limitations occur.
NOTE: Stored readings are not lost during battery replacement or low battery conditions.
Current meter settings are maintained as well.
