The BEGIN TIME data entry display will initialize with the current time shown as a reference. Enter a BEGIN TIME using
the number keys. If the user does not revise the BEGIN TIME before pressing the READ/SELECT key, the reading
process may be started manually by pressing the READ/SELECT key following the [STORE ALL / TIMED RDY / PRESS
READ] display sequence. Press the READ/SELECT key to confirm the BEGIN TIME entered and advance to the END
TIME data entry display.
The END TIME data entry display will initialize with the BEGIN TIME shown as a reference. Enter an END TIME using the
number keys. If the user does not revise the END TIME before pressing the READ/SELECT key, the reading process will
run until either the 2000 reading memory is full, or the user presses the READ/SELECT key to HALT the reading process.
Press the READ/SELECT key to confirm the END TIME entered and advance to the MAXIMUM reading display.
The MAXIMUM reading display will default to 2000 readings, the maximum number of readings which can be stored in
memory. Enter the required number of readings using the number keys, and then press the READ/SELECT key to confirm
the number of readings.
The meter will display [STORE ALL / TIMED RDY / PRESS READ]. When the READ/SELECT key is pressed, the timed
reading process will begin. The meter will display [BEGIN WAIT], followed by [TIMED READ] during the actual reading,
then display the actual reading, then display [TIMED WAIT] between readings. [TIMED DONE] will be displayed when the
timed reading process is complete.
The time at which a reading is taken is recorded at the end of a reading, after as few as one, or as many as eight seconds
of sampling time. For this reason, timed readings that were programmed to start at perfect intervals may create readings
whose time stamps are not so perfectly separated in time.
If the timed reading sequence is halted, either manually or automatically, it can not be started again. Additional readings
may be added to the current memory group by beginning a new TIMED READ sequence.
5.9.3 CONFIGURATION SETTINGS
Units (English or metric), density (local or standard), time and date are specified using the configuration loop. These
settings are saved indefinitely in memory with the exception of standard density. The meter always initializes in the local
density mode, unless the user has stored standard density readings in the
currently selected memory group.
Press ALT / MODE / ALT / MODE to access the configuration setup loop. The meter will flash the name of the selection
loop [CONFIGURE], then display [UNITS s]. Press the MODE key repeatedly to scroll through [UNITS s], [DENSITY s],
[TIME s], and [DATE s], then press the READ/SELECT key while the required option is being displayed.
5.9.3.1 CONFIGURE UNITS
Press the READ/SELECT key while [UNITS s] is being displayed. [ENGLISH s] will be displayed. Press the MODE key
to toggle between the two units options, [ENGLISH s] or [METRIC s], then press the READ/SELECT key to choose the
desired type of units.
5.9.3.2 CONFIGURE DENSITY
Press the READ/SELECT key while [DENSITY s] is being displayed. [LOCAL s] will be displayed. Press the MODE key
to toggle between the two density options, [STANDARD s] or [LOCAL s], then press the READ/SELECT key while the
required density is displayed.
The density setting must remain consistent for all readings taken within a memory group. In order to store readings with
a different density than previously used, select a new memory group, then immediately select the required density, and use
it consistently until the readings for that memory group have been completed.
NOTE: If the meter is turned off, either manually or automatically, the meter will reset the density selection from
standard density to local density, unless standard density readings have been stored in the currently selected
memory group.
5.9.3.3 CONFIGURE TIME
The meter may be configured to use either a 12-hour clock or a 24-hour clock. Press the MODE key repeatedly while in
the CONFIGURE loop, until [TIME s] is displayed. Press the MODE key to toggle between the 12 and 24 hour options,
then press the READ/SELECT key to select the format required.
The default time setup is a 24 hour clock. The meter will display its current time in the 24-hour format with colons between
the hours, minutes, and seconds. For example, [16:45:19 T] (rather than 4:45:19 PM). If the current time is correct and
no corrections are necessary, press ALT / ALT to exit the selection loop or press the READ/SELECT key to accept the time
displayed.
