0x0000 = 0 V and 0x7FFF = 10 V.
Values from 0x8000 to 0xFFFF are
ignored in this setting or always provide
the lower endpoint of the range (i.e.: 0 V,
0 mA, 2 V, 2 mA etc.).
16 Bit
*)
With resolution “16 Bit,” the entire
numerical range is provided for the output
value.
Example:
With a measurement range
setting of “0–10 V,”
0x0000 = 0 V and 0xFFFF = 10 V.
Channel
diagnosis
Off
Switches diagnostics on/off for the
channel in general. Switching off channel
diagnostics causes the settings for the
individual diagnostics “wire break,” “short
circuit” etc. to be ignored. The status byte
then also always remains at 0x00 when
there is a pending diagnosis.
Note:
If channel diagnostics are switched
off for this channel, the global diagnostic
settings (see “Common” menu item) are
ignored for this channel!
