5.4 Special functions
5.4.1 Different pressure units
Depending on the connected sensor, in
“MENU (Unit)”
different units can be selected.
Depending on the measuring range, the selection may be limited!
User unit
For units which are not covered by the units imprinted on the display, a manual setting
can be made via the user unit.
Example:
So that the unit kg/cm² can be displayed with a CPT6200 reference pressure sensor, this
must be set:

5.4.2 Different measuring modes
The instrument supports 3 different measuring modes for various purposes. Two
of these,
P
.
dEt
and
FASt
, operate with an increased measuring frequency of
> 1,000 measurements/s.
5.4.2.1 Standard measurement (slow)
rate sLo
Measuring rate 4 Hz, averaging and filter functions are active.
Application range:
Measurement of slow pressure changes and static pressures, e.g. leak
testing, atmospheric pressure measurements, etc.
Highest measuring accuracy, insensitive to disturbances, low current
consumption.
5.4.2.2 Peak value detection (Peak detection)
rate P
.
det
Measuring rate > 1,000 Hz; the value is displayed unfiltered.
Field of application in combination with logger function:
Measurement of pressure spikes or fluctuating pressures with a
resolution of < 1 ms. The cyclic logger function records the arithmetic
mean value, the highest and the lowest peak during the chosen time
interval.
