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.
