Calibration Procedures

4. Select the Calibration access level.
Standalone FlexTest SE Controllers: Select Config > Access Level >
Calibration
Automated Controllers: In the Station Manager window toolbar, select
Calibration
5. Set up a signal monitor.
See
for more information.
6. Mount the force standard.
7. If you are using Gain/Delta K or Gain/Linearization for calibration, set
initial conditioner calibration values on the Calibration submenu. A typical
complement of ranges could be: 100%, 50%, 20%, and 10% of full scale.
You can create ranges for any percentage of full scale. This creates a sensor
calibration file and sets up any ranges you may want.
Example: Suppose you have an actuator with a full-scale capacity of ±10
kN. You might create ranges for ±10 kN, ±5 kN, ±2.0 kN, and ±1.0 kN.
Note
Some systems do not provide or require multiple ranges, such as those
using full-range conditioners (e.g., Model 493.25 DUC module). In this
case, only one range is used (typically 100%).
Force Transducer
Load Standard
The illustration shows a load
standard in-line with the
force train coupled with the
force sensor.
The load standard reacts like
a stiff specimen. Be sure the
gain settings (PID) for the
control mode are
appropriate.
If the control mode has not
been tuned yet, use some
default values. Then
recalibrate the sensor after
the initial tuning.
