the memory is full, the user may make non-stored readings in the MANUAL or AUTO read modes.
If the meter was in a STORE mode when it was turned off, it will display the last reading taken along with the STORE mode
when it is turned on again.
5.7.1.1 STORE ALL
Press STORE repeatedly until [STORE ALL] is displayed. Subsequently, every reading taken will be stored in memory.
Press the READ key to take a reading. The meter will display the number of the reading in the sequence and the letter of
the memory group. For example, [01A 365] would be the first reading in memory group “A”.
The automatic reading function and the memory function may be used together to store up to 2000 automatic, repeated
readings within a single group. This measurement and storage process will continue until interrupted by pressing the READ
key, or until the meter registers STORE FULL at 2000 readings.
Press the STORE key to select the memory mode, followed by the ALT key, then press the READ key to select automatic
readings. The meter will display [AUTO STORE], at which point the actual measurements are initiated by pressing the
READ key. The auto-reading memory sequence may be interrupted by pressing the READ key. [HALT] will be displayed,
followed by the last reading taken. The auto-reading memory sequence may be resumed by pressing ALT / READ again.
The TemProbe status, units (English or metric) and density selection (local or standard) must remain consistent throughout
a memory group. If memory group “A” is begun with a pitot tube reading using a TemProbe, then all following velocity and
flow readings in Group “A” must also use the TemProbe. If the probe is removed and the user attempts another pitot tube
reading, the meter will briefly display [TEMPROBE / CHANGE / NOT ALLOWD] and will not execute a reading.
The user may turn the STORE mode off while in a particular memory group. The user may then change the TemProbe
status, units and density selection and take non-stored readings. If the units have been changed, when the user presses
STORE to return to the current memory group, the meter will automatically restore the units previously used to store
readings. The meter will display the following sequence [STORE ALL / STORE MODE / UNITS / RESTORED].
If the density was changed, and the meter is being used in the FlowHood or velocity modes, the meter will also display
[DENS CHANGE / NOT ALLOWD] and will not store a reading until the density is set back to that previously used to store
readings in the current group.
5.7.1.2 STORE LAST
The STORE LAST mode is selected by repeatedly pressing the STORE key until the meter displays [STORE LAST]. Press
READ to take a reading. The meter will display the results along with the potential sequence of the reading and a question
mark. If the user presses READ while the question mark is being displayed, the meter will discard the displayed reading,
take a new measurement, and will display the new measurement with the potential sequence and a question mark. If the
user presses the STORE key while the question mark is being displayed, the meter will store the reading in the current
memory group, then display the measurement value and its sequence in the current memory group. The STORE LAST
mode may only be used with the MANUAL reading mode.
An individual reading may be abandoned in the STORE LAST mode while the meter is displaying the result of the reading
with the question mark. Pressing ALT / ALT will delete the reading, the meter will display [ESCAPE], will sequence through
the meter status displays, and then display [STORE LAST]. Previously saved contents of the memory group are not
affected and the currently selected memory group is not changed.
5.7.1.3 STORE OFF
Press STORE repeatedly until the meter displays [STORE OFF] to return to the MANUAL reading mode. Manual or
automatic manual readings may be taken without affecting the contents of the current or prior memory groups.
5.7.2 CLEAR MEMORY
The ALT / STORE sequence is used to clear all readings stored in memory. Press ALT / STORE. The meter will briefly
display [MEM CLEAR], then display [CLEAR MEM s]. Press the READ/SELECT key. The meter will display [CLEAR MEM]
and erase all readings from memory. If readings have been stored in more than one memory group and/or more than 50
readings have been stored in a single memory group, the meter will display an additional message [?CLR ALL?s]. If the
READ/SELECT key is pressed again, the entire contents of the memory will be erased. After clearing the memory, the
meter resets the memory group letter to the default “A”.
5.7.3 CHANGE MEMORY
This key sequence is used to change to a new memory group and to erase or replace readings in memory.
