INSTALLING THE BATTERY:
The battery compartment is located on the underside of the case, at the bottom of the handle.
1. Open the battery compartment by sliding the lid back while pressing on the release indent.
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.
