8 Interval Functions, Ramp Functions and Procedures
Two types of setpoint sequences can be generated in order to
simulate sensor conditions at the inputs of transducers,
transmitters and buffer amplifiers:
• Interval sequences (see section 8.1)
Automatic (periodic) or manually controlled sequences
or
• Ramp sequences (see section 8.2)
Endless loops (periodic) or one-time only sequences
The above mentioned sequences can be conveniently generated
at a PC with the help of METRAwin90-2 software as an
accessory.
8.1 Interval Sequences – INT Function
Output ranges are divided into rising or falling interval steps with
this function, and the number of interval steps, as well as their
duration, can be specified. This function is above all suitable for
calibrating analog displays and recorders during one-man
operation.
Input parameters for interval sequences:
• All simulation functions except for Hz can be adjusted as
output quantities.
• A lower (Start) and an upper (
End) range limit can be selected
for each output quantity from within the overall range.
• The number of steps can be set within a range of 1  99.9.
The number of steps can be entered as a whole number as
well, which is especially practical for analog indicators and
recorders with non-standardized scale divisions.
• The interval duration per step (t1) can be selected from within
a range of 1 second to60 minutes.
• Step jumps can be executed manually (
1nt mode = manual) with
the  and  keys, or automatically (
1nt mode = Auto ) with
selectable time per step.
