Configuring the Display
The display indicates the sample load in units of Pounds-Force (Lbf ) and stores the
maximum value. The display may be configured for other units of force by rescaling the
display and controller. Contact Chandler Engineering for instructions if the display must be
rescaled.
Note that the value displayed by the controller must be multiplied by 10 to obtain Lbf. The
display indicates in units of Lbf directly.
The display provides the peak value to the 5270 Data Acquisition software every 1 second
using the serial communication port.
Note: The scaled peak value is available at Modbus register 133 (2:133f). To reset
the peak value, 5270 must be configured to transmit a 0 to Modbus register
133 (2:133f) when a test is started. This is accomplished using the Start
Sequence option in the instrument Test Profile definition. The device address
and register (2:133f) must be configured in the Advanced option for the Lbf
load signal.
Note: The display calibration is based on the calibration certificate provided with the
load cell and the excitation voltage (+10Vdc). If the instrument must be
recalibrated, an independent load cell must be loaded into the press and used
to validate the output of the load cell in the instrument. Any changes to the
