2. press
LM-STOP to stop long-term measurement, the display is frozen and the average value is
displayed above the measurement period in seconds (e.g. S00030).
3. press
LM-OK to exit display of average value, the instantaneous value is once again displayed and
is ready for a new measurement. Start a new measurement as described under 1.
LM Start mode is set:
1. press
LM-START to start long-term measurement. The instantaneous value is displayed and the
duration of measurement in seconds (e.g. S00010) is displayed continually. The bar above the control key
description shows the progress of the measurement period in relation to the set interval.
2. press
LM-STOP before reaching the set interval and long-term measurement stops, the display is
frozen and the average value is displayed above the measurement period in seconds (e.g. S00020).
If LM-STOP is not activated, the measurement period runs up to the set interval, then long-term
measurement is stopped, the display is frozen and the average value is displayed above the measurement
period in seconds (e.g S00030).
3. press
LM-OK to exit display of average value, the instantaneous value is once again displayed and
is ready for a new measurement. Start a new measurement as described under 1.
LM Automatic mode is set:
1. if
LM-START is pressed, long-term measurement commences, in the 1
st
interval displaying the
instantaneous value, in the status field top right the measurement period in seconds (e.g. S00010)
continually and below this the number of measured values (R00001). The bar above the control key
description shows the progress of the measurement period in relation to the set interval. Ater the 1
st
interval has elapsed the display is frozen and the next interval starts automatically, displaying the average
of the previous interval during the set length, the measurement period in seconds continually in the status
field and below it the number of values (R00002), ...
2. if
LM-AUTO is pressed before the set number of long-term measurement transmissions is reached,
then long-term measurement is aborted and awaits a new input as under 1.
If LM-AUTO is not activated, the measurement period runs to the end of the set number of intervals, long-
term measurement is then stopped, the display frozen and displays the last average value above the
displayed measurement period in seconds in the status field top right, and below it the number of
recorded values.
3. press
LM-OK to exit display of average value, the instantaneous value is once again displayed and
is ready for a new measurement. Start a new measurement as described under 1.
If the data logger is switched on (see 5.3.24.1), the displayed average is saved to the data logger
with time stamp after each interval sequence, in the 3 modes described above.
LM single measurement mode is set:
1. each time
LOG + is pressed the displayed instantaneous value is buffered as an individual value
and the number of the buffered values (e.g. +00010) is displayed in the status field top right.
2. by pressing
LOG – the last recorded individual value is deleted and in the status field top right the
number of buffered values (e.g. +00010) is reduced by one. At the most the last 10 individual values may
be discarded.
