range is specified with variables 15 and 16. The output is linear
between the two specified values. Variable 19 is used to set the analog output
response time. Variable 22 is used to set the bottom end cutoff
The REV key is used to change the direction associated with the value.
Variable 15,
4 mA display
This variable contains the display value at which the analog output is 4 mA or 0
VDC. The default is “0.”
Variable 16,
20 mA display
This variable contains the display value at which the analog output is 20 mA or 10
VDC. The default is “1800.”
Note: Variables 15 and 16 can be set up for reverse direction or as a window, 200

Variable 19,
analog output
response time
The variable sets the response time of the TR400's analog output from 0 to 100
percent. The TR400 will limit how much the analog output can change as the input
frequency changes, filtering the output. The minimum response time is “0.0,” which
corresponds to approximately 50 msec from 0 to 100 percent. The maximum
response time is 10.0 which corresponds to (10) seconds. The default is “0.0.”
Variable 22,
analog output
cutoff
This is used to set when the analog cuts off to zero. It can be set from 0.0 to 10.0
percent. This is used to speed up the zeroing of the analog output to zero out.”
