6.3.3 Battery voltage display

The current battery voltage as well as the remaining useful life of the battery are displayed
via the battery symbol.

6.3.4 Current temperature display

The gas density indicator is temperature-compensated for SF6 gas. This option displays
the temperature measured by the internal sensor. The value indication can be switched
from degrees of Fahrenheit to degrees of Celsius.

6.3.5 Setting the damping

With the "Damping" setting, one can select between three different, fixed, preconfigured
filter settings. With "Off", the filter is inactive and not in operation. Thus only the display
on the gas density indicator is damped. The pressure value that is read over the wireless
transmission or the value written to the logger will not be damped.

6.3.6 Configuring the sampling rate

The sampling rate defines how frequently the density or the pressure is measured.
Options for SF₆ gas are 1 and 3 measurements per second or the logger interval.
Standard pressure values can be recorded with 1, 3, 10 and 50 measurements per
second. The shortest response time for SF₆ gas is 3 measurements per second and
for standard pressure values, 50 measurements per second. The display rate is set
permanently at 3 x display refresh/s.
6.3.7 TARE (Tare setting, not available for SF₆ units)
With this option, a constant offset value can be set. If, for example, TARE is set to 10 bar
and the measured pressure is 13 bar, the measured value will be displayed as 3 bar.
A pressure of 7 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 measurement 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 unit, the configured
offset value will be automatically converted to match the new unit.
