6.4.6 Configuring the sampling rate

The sampling rate defines how frequently the pressure is measured. The options
available are 1, 3, 10 and 50 measurements per second or logger interval. The shortest
response time is 50 measurements per second.

The display rate is set permanently at 3 x display refresh/s.

6.4.7 TARE (setting tare)

With this option, a constant offset value can be set. If, for example, TARE is set to 30 bar
and the measured pressure is 37 bar, the measured value will be displayed as 7 bar. A
pressure of 27 bar would then be displayed as -3 bar. The TARE value is set manually
using the ▲ and ▼ buttons and depends on the technical units of measure and the
resolution selected for the display. The TARE value can be set to the maximum scale
range.
The bar graph always indicates the actual pressure with respect to the entire measuring
range, irrespective of the tare setting. This is performed for safety reasons so that in case
of "0" indication it can still be displayed that the corresponding pressure is present at the
pressure gauge.
Contrary to the operating principle of the ZERO button, the offset value under tare does
not contribute to the shift of the characteristic curve. If you change the pressure unit, the
configured offset value will be automatically converted to match the new unit.

6.4.8 Function locking

Access to adjustable parameters can be selectively turned off, once set, to prevent
unauthorized changes to configuration.
Locking the Zero button
The operator can no longer make a "ZERO" using the keypad - it is still possible over the
wireless transmission.
Locking the Menu button
Access to the "Menu" is locked. If "ZERO" is not locked, this can still be executed. Over
the wireless transmission, all settings can still be read or written.
Instrument write protection
When this lock is set, via the menu on the local display menu as well as over the wireless
transmission, access to the settings is read-only - thus no alteration of the settings is
possible.
If the "ZERO" lock is not set, the "ZERO" function is still possible.
The individual locks can only be set via WIKA-Cal calibration software over the wireless
transmission. For this, the input of a 4-digit PIN is required. This is set to "0000" on supply
and can be changed.
