Setting 0 % and 100 % Output
Parameters
For current output, the Calibrator assumes that 0 %
corresponds to 4 mA and 100 % corresponds to 20 mA.
For other output parameters, 0 % and 100 % points must
be set before using the step and ramp functions. Proceed
as follows:
1. If necessary, press
M for SOURCE mode.
2. Select the desired source function and use the arrow
keys to enter the value. This example is temperature
source using 100 °C and 300 °C values for source.
3. Enter 100 °C then press and hold
J to store the
value.
4. Enter 300 °C then press and hold
G to store the
value.
This setting can now be used for the following:
• Manually stepping an output in 25 %
increments.
• Switch between the 0 and 100 % span points by
momentarily pushing
J or G.
% Error Functionality
Percentage Error is available for every range on the
lower display. The calculation is based on a mA
percentage deviation
from the value measured on the
upper display to the value sourced on the lower display
0 % mA and 100 % mA are fixed to 4 and 20 mA. 0 %
and 100 % for the lower display are set in source using
J and G, refer to “Setting 0% and 100% Output
Parameters”.
Stepping and Ramping the Output
Two additional features are available for adjusting the
value of source functions:
• Stepping the output manually with the
H and I
keys, or in automatic mode
• Ramping the output
Stepping and ramping apply to all functions except
pressure, which requires use of an external pressure
source.
