Calibration gas N, X Note:
Effective control only possible in "Measuring" operat-
ing state!
Relay must be configured for calibration gas. After the
input is set, the device changes from "Measuring" to
"Calibrating" operating state. See also "Example of
binary inputs"
Sample gas N, X Note:
Effective control only possible in "Measuring" and
"Calibrating" operating states! For FIDAMAT 6-G,
also from "Standby", whereby the device requires a
short time to build up pressure.
Relay must be configured for sample gas. Before the
sample gas valve opens, the other valves are closed.
The device then switches to the "Measuring" operat-
ing state, and all other states (e.g. "Calibrating") are
exited.

Measurement
protection
N, X It is possible to define a binary input "Measurement
protection" that has the following effect:
If the device is in "Measuring" operating state (func-
tion control deactivated), it remains in this state, i.e.:
• The device can no longer be decoded.
• The device can no longer be set to "Remote".
The message "Measurement protection activated"
appears in the status line of the measured value
display.
Standby N, X Sets the "Standby" start-up state (Function 91). This
allows the sample gas pump to be switched off. Only
valid for FIDAMAT 6-E (with pump) firmware version
V1.3.5 or higher.
