9.10 Special Functions
The data logger 5990-2 has a separate
menu allowing access to all ALMEMO
®
special functions, which despite only rarely
being required during routine operation, are
very useful for some applications (see
manual 6.10). These functions can (to a
certain extent) be very complex and should
only be used if their operation is completely
understood.
9.10.1 Print Cycle Factor
For the adaptation of the data recording to the update speed of the individual
measuring points it is possible to program a print cycle factor between 00 and
99 to print measuring points less often or not at all (see manual 6.10.6). Only
disturbed measuring points, e.g. on exceeding of limit values will always be
output. Generally, the print cycle factor of all measuring points is cleared or set
to 01, i.e. all activated measuring points will be printed at each print cycle. If a
different factor, e.g. 10 is programmed, the corresponding measuring point will
only be printed once in ten times, however, if 00 is programmed it will not be
printed. The data recording within the print cycle also allows to suppress
unnecessary measured values and, as a result, saves memory space.

9.10.2 Minimum Sensor Supply Voltage
Generally, the ALMEMO
®
devices monitor the sensor supply voltage, which, in
most cases, corresponds to the operating voltage of the measuring instrument.
It is also displayed in the device configuration (see 10.8). However, there are
also sensors, which require for a correct operation a supply voltage, which
requires a charged battery or a power supply unit. TO avoid measuring errors,
the sensor programming allows to individually program the required minimum
sensor voltage for each transducer. In case of falling below this voltage the
measured value is treated as sensor breakage.
Entering the minimum sensor supply voltage:
U-Sensor Min: 12.0 V
Switching off the voltage control, clearing the value: <
