Device parameters
Several parameters are available for adapting instrument operation to a number of
different applications. Section 6.1 describes how to set parameters; table 3 provides
an overview of available parameters.
Parameter
Description
basic settings
time constant
the amount of time required for the display, analogue output and (if
the corresponding parameters are set) switching outputs to
respond to changes in pressure
brightness
display brightness
zero-point
calibration
automatic or manual zero-point calibration options
relay output 1
switch-on value
pressure threshold value that activates the switching output, see
section 3.4
switch-off value
pressure threshold value that disables the switching output, see
section 3.4
switch direction
parameter for selecting one of the two possible directions between
the two relay/transistor output states, see section 3.4
switching output 2 (analogous to switching output 1)
switch-on value
see above
switch-off value
see above
switch direction
see above
