FLOW H CFM
This message is part of the ASSOCIATED READING sequence and precedes the display of the temperature and
absolute pressure readings associated with an air flow reading.
FLOW ONLY
[FLOW ONLY] will be displayed if the operator inserts the FlowHood flaps plug while the meter is in a velocity or
differential pressure measurement mode and presses the READ key.
GRP IN USE
This message is displayed to indicate that the user is selecting a memory group that is currently in use, or already
has been used. New readings can not be added to a memory group after it has been exited.
HALT
This message will be displayed when an automatic reading, automatic reading storage, or TREND mode sequence
has been halted manually by pressing the READ key. The individual readings, or the average, total, minimum,
maximum and standard deviation of the readings, may now be displayed if the auto-reading memory function is being
used.
If the TREND mode is being used, the meter will revert to the MANUAL reading mode and the last reading displayed
will be a standard MANUAL reading.
LIGHT OFF
This message indicates that the display backlight has been turned off. Battery time is extended when the backlight
is turned off.
LIGHT ON
This message indicates that the display backlight has been turned on. Battery time is reduced when the backlight
is turned on.
LOCAL DENS
This message indicates that flow or velocity readings will be corrected for local air density. The meter automatically
starts up in the local density mode, unless the meter was last turned off with readings stored in the standard density
mode.
LOC DENS s
This prompt indicates that local density is being selected using the meter configuration loop.
LOCHARGE
This message indicates that the battery cells are nearing the end of their useful charge. The meter will continue to
function normally for about twenty minutes, depending on light use, before recharge is required. The third character
of all MANUAL, AUTO and STORE readings will become the symbol for an empty battery cell.
MANUAL
This message is flashed when the user halts a series of TREND readings, as the meter reverts to the MANUAL mode
and takes a final, MANUAL reading.
MEM CLEAR
This message is flashed when the ALT / CLEAR keys are pressed to clear the AUTO STORE mode.
MEM EMPTY
This message indicates that the meter is in STORE mode, but no readings have been saved.
METRIC
This message indicates that the readings will be in metric units. This option is selected using the CONFIGURE loop,
which is accessed by pressing ALT / MODE / ALT / MODE. [UNITS s] is displayed as the first option. Press the
READ key to select the UNITS loop. Press the MODE key to toggle between metric and English units, then press
the READ key to select the units required. The meter will save the units selection (metric or English) and will
automatically default to the selected units the next time it is turned on.
METRIC s
This prompt indicates that metric units are being selected using the meter configuration loop.
