BATTERY INSTALLATION and REPLACEMENT
Battery Installation:
All meter mounted confi gured IT 300N models are shipped without the batteries installed. When using external
BATPACK, mount within 12" and plug connector into 3 position square posts (see Fig 1). Polarity is not a concern
because center is common.
To install the batteries, begin by locating the battery holder. This requires opening the enclosure cover and removing
the IT 300N to expose the battery holder.
The plus terminal of the battery is marked with a (+) symbol stamped into the battery holder. Be sure to install the
batteries correctly.
Install batteries to begin setup procedure. See Programming Flowchart to setup desired operating parameters.
Battery Replacement:
The IT 300N has a battery monitor feature which illuminates when the lithium battery voltage approaches its end
of life. A descriptor, “BAT”, illuminates when the battery voltage falls below this predetermined value. The low bat-
tery detector operates correctly with all power options.
The battery, or batteries, should be replaced within several weeks of the fi rst occurrence of low battery warning,
“BAT”. Left unattended, the unit may become inaccurate, cease to operate or malfunction.
Before replacing the battery(ies), Press the ← (left arrow) key to save the totalizer. The display will show "SAVE
TOTAL". This will save the current total value and the total will resume from this value when the new battery(ies)
is(are) installed. NOTE: If the display starts to fl ash after the "
SAvE totAL" message times out, press the "E" (enter)
key. If the message "E FLASH" is displayed, then there was not enough power left to save the setup and totalizer
to fl ash memory. At this point you must record the totalizer and setup information and re-enter the setup data after
the new battery(ies) is(are) installed.
Install new battery(ies) as described above.
