9.3 Peak value memory

est and the lowest values are continuously
recorded. To display these peak values press
key

or
MIN
. As a check the display
also includes the associated symbol.

As soon as you clear the memory, the current measured value will appear (be-
cause measuring is continuous).
9.4 Measured value memory
On the THERM 2420 any measured value can
be saved. To save the measured value press
key
MEM
The currently saved value then ap-
pears in the function field preceded by the
symbol ´
M ´. To jump back to the operating
range display press key :
M▲
9.5 Relative measuring
One very useful function is to zero the mea-
sured value at certain locations or at certain
times as a reference value in order then to ob-
serve only the subsequent deviations.
By default this function is also locked in the de-
vice configuration (display ´
LOC
´ ) (see 10).
To zero-set the measured value press key :
CLR
To display relative measuring press arrow :
REL
To return to normal measured value :
press and hold down CLR
Setting to zero automatically deletes the maximum and minimum val-
ues for this channel. The MAX , MIN , and MEM functions are thus also
available for relative measuring.
