• Forced power off on low battery detection causes the log run to

be stopped before power is turned off.

• The zero key is active and an event record (including the change

in the zero offset value) is placed in the log.

• Auto off is disabled. It is restored to its original value at the end

of the run.

• The engineering units, damp, sample rate, tare, and custom

factor items on the existing configuration menu are disabled.

• The units field on the display cycles between the units, the text

LOG, and the text RUN at a rate of once per second. This
provides visual feedback that data logging is active, and the
number after the text RUN identifies the run number for later
reference.

3.3 Demand Mode

The Demand mode allows the user to conduct an impromptu data
measurement/log without the need of a computer to configure all of the
logging parameters.

Once data logging functionality is enabled, a new item is inserted at
the start of the configuration menu tree to direct the user to a
completely separate branch which contains all data logging functions.
This new menu item shows 'LOG' in the main display and 'DATA' in the
secondary display. Press the CONFIG key to proceed to the existing
configuration functions, or press the ENTER key to proceed to the new
data logging branch. The data logging configuration menu sequence
(new branch) is as follows:

1) Start or stop data logging

• Main display: LOG

• Secondary display: FULL if the log memory is full, OFF if not

logging data, else ON if logging data.

• the ▼ and ▲ keys are ignored if the log memory is FULL,

otherwise press either key to toggle between OFF and START if
not logging data, or to toggle between ON and STOP if logging
data.

• press the CONFIG key to step to the next menu item.

• press the ENTER key to exit configuration if the display is FULL,

ON, or OFF, to stop logging and exit configuration if the display
is STOP, or to start logging and exit configuration if the display is
START.
