READING
This message is displayed following MANUAL during the manual reading that is taken when a series of TREND readings
is halted.
RECHARGE
This message signals that the batteries have reached the end of their useful charge, and must be recharged. The meter
will turn off following the display of RECHARGE.
SHUT DOWN
The meter will display SHUT DOWN and turn itself off if the battery charge becomes too low or if the meter is exposed
to temperatures beyond the specified limits.
STD 70
/F or STD 21.1/C
This message will be flashed during air flow measurements performed without the TemProbe. The resulting flow value
will be calculated using the standard temperature, 70
/F or 21.1/C. The correction for the ambient barometric pressure
will still occur.
TEMP
This signal will be flashed when the Temperature mode is selected, and also upon each subsequent operation of the
READ key.
TOO HOT or TOO COLD
If the internal temperature of the meter exceeds its operational limits, the meter will display TOO HOT or TOO COLD
and shut down. The meter must be cooled down or warmed up, as the case may be, before normal operation can
resume.
If the meter has displayed OVER RANGE after displaying either TOO HOT or TOO COLD, but has not shut down, this
message indicates that the TemProbe sensor was being exposed to temperature levels beyond the proper operating
range. If TOO HOT/OVER RANGE has been displayed, but the meter has not shut down, the TemProbe sensor may
be short circuited.
TOO LOW
This message indicates that the battery charge is very low and the back-light may not be used until the batteries have
been recharged (NO LIGHT/BATTERY/TOO LOW).
TREND
This message indicates that the meter is being used in the TREND mode.
UNDER TEMP
This display advises the operator that the temperature measurement being attempted exceeds the lower range of the
meter.
