h) Flow Rate Precision (Tabular entry)
The DPM Flow Meter calculates Flow Rate Precision automatically, based on selected
units of measureandcurrent gas full scaleflowratetokeepthe reading. Bydefault,
the Flow Rate Precision is set to “Normal”. In cases where more digits after the
decimal point are required, the usercanchangedecimal point precisionto the
“Elevated”level (one moredigit after the decimal point).

The DPM instrument is equipped with a universal transceiver which
supports both RS-232 and RS-485 interfaces. The following settings are
available:
x
Disabled
x
RS-232
x
RS-484
NOTE: The instrument is shipped from the factory with the
communication interface type set according to your order.
NOTE: In some cases, selecting “Elevated” precision may result in unstable
readings (the last digit constantly changes). In such cases, we recommend
switching the decimal point precision to the “Normal” level.
NOTE: If Screensaver mode is active and has been changed, new
settings will be activated in the next Screensaver cycle (after the Esc
button or joystick interface was activated to disable the currently active
screensaver). The OLED “Screensaver Brightness Level” parameter is
only applicable for “Low Brightness” Screensaver mode. In “Vertical
Scrolling” mode, the normal operational brightness level will be
activated. If OLED display is not used in the user application (e.g., the
meter is installed in a remote enclosure), we recommend setting the
Screensaver mode to "OLED Off".
