displayed as nnR nn, where nnR is the sequence number of the reading and nn is the actual reading. Subsequent readings
will be displayed in succession.
The reading and memory entry process will continue as long as the READ key is pressed (up to a maximum of 200
readings). Press the STORE key at any point to view the sum and the average. The number of readings that have been
taken, along with the average of the readings will be displayed, such as 070 395. The first two or three digits are the
number of readings taken. Press the STORE key again to display the sum of the readings. The number of readings in
memory will not be displayed with the sum.
Press the STORE key again to display the minimum reading. The sequence number of the reading will be displayed along
with the minimum reading, such as xx
º n.nnnn. Press the STORE key again to display the maximum reading. The
sequence number of the reading will be displayed along with the maximum reading, such as xx
¸
n.nnnn. The
measurement sequence may be resumed by pressing the READ key, and may be interrupted at any point by pressing the
STORE key again.
The measurement mode or other conditions may not be changed while the meter is in the memory function.
Air flow readings may be saved as either a sequence of nonbackpressure compensated readings, or as a sequence of
alternating nonbackpressure compensated and backpressure compensated readings, with display of the sum, average,
minimum and maximum reading available for each type of reading. See Section 11.1 AIR FLOW - NONBACKPRESSURE
COMPENSATED READINGS and Section 11.2 AIR FLOW - BACKPRESSURE COMPENSATED READINGS for more
information.
The TemProbe must not be connected or disconnected during a STORE sequence. If this occurs, TEMPROBE will be
displayed followed by CHANGE. The TemProbe must be reconnected or disconnected before further readings can be
taken. The STORE mode may be exited by pressing SHIFT/CLEAR if no further readings are needed.
If the meter's full capacity of 200 readings has been reached, STORE FULL will be displayed. Press the STORE key to
alternately display the average and sum, or one of the RCL keys for recall of the individual readings. The memory must
be cleared before a new reading sequence may be begun.
5.4.2 RECALL
The RCL keys are used while a reading sequence is halted to sequentially recall all readings that are in memory.
= RCL
displays the last reading stored, and then displays readings in reverse order. RCL
< displays the first reading stored, and
then displays readings in the order entered. These keys may be used either before or after the STORE key has been
pressed. The sequence of the reading will be displayed along with the reading, such as 07s 395. A brief press of a RCL
key will advance the display one number at a time. Holding a recall key down will fast forward or fast reverse the display
through all the numbers that are in memory.
5.4.3 REPLACE READING IN MEMORY
A reading in memory may appear to be abnormal, or may have been taken at the wrong time, or with an improperly
positioned sensor. Readings stored in memory may be replaced with a new measurement. Press one of the RCL keys to
toggle through the individual readings in the stored sequence. Select a specific reading such as: 07s 395. This reading
may be replaced while it is on display by pressing the MODE key. REPL n? will be displayed where n is the sequence
number for that reading. Press the READ key. The meter will initiate a new reading and the result will replace the value
previously stored for that position in the sequence. REPLACING will be displayed while the meter takes the new reading
and stores it to memory. The new sum and average will be calculated using the new measurement and may be displayed
by pressing the STORE key.
5.4.4 ERASE READING IN MEMORY
Readings stored in memory may be erased without replacement. Press one of the RCL keys to toggle through the individual
readings in the stored sequence. Select a specific reading such as: 07s 395. This reading may be erased while it is on
display by pressing the MODE key twice. ERASE n? will be displayed where n is the sequence number for that reading.
Press the READ key. ERASING will be displayed. The erased reading will now be displayed as nn
S ERASED. There will
be no value associated with that place in the sequence and the reading may be left blank or may be replaced with a new
reading. The sum function will disregard the erased reading unless it is replaced. The average function will display the
revised number of readings included in the average and the average of the revised sequence.
5.4.5 CLEAR MEMORY
The memory is cleared and the STORE mode is exited by pressing the SHIFT key followed by the CLEAR key. This
sequence removes all readings from memory. Press the STORE key a second time and a new averaging sequence will
