Operation
Analog Outputs (Continued)
Analog Output Input Mode
Select Input to set output voltage proportional to an
input reading. Several parameters associated with
this mode allow flexibility. After selecting Input mode,
the screen to the right appears. Use the Data
Selection keys to select the sensor input (1-8) that
the selected analog output follows. Press Enter
when the desired input appears.
The second display in the Input mode setting
sequence appears. Use the Data Selection keys to
select the appropriate source for the selected sensor
input:
K
Kelvin temperature reading from input.
C
Celsius temperature reading from input.
Sensor
Sensor units reading from input.
Linear
Linear equation data from input.
Press Enter when the desired unit appears.
The third display in the Input mode setting sequence
appears. Use the Data Selection keys to turn Bipolar
Mode On or Off, then press Enter. Bipolar allows the
analog output to set a negative voltage:
On
Allows a range from –10V to +10V
Off
Allows a range from 0 V to +10V
The fourth display in the Input mode setting
sequence appears. Use the number keys to input a
value corresponding to the lowest setting of the
analog output, then press
Enter
. For bipolar
operation, this value corresponds to –10 V out; for
unipolar operation, it corresponds to 0 V out.
Resolution is 5 digits.
The fifth display in the Input mode setting sequence
appears. Use the number keys to input a value
corresponding to the highest setting of the analog
output, 10 V, then press
Enter
. Resolution is 5
digits.
Press
Escape
at any time to return to the normal
display. The instrument retains values changed prior
