CONFIGURATION
T
his product is configured using the USB port of a PC running USB_Speed_Link software, available from your suppliers. During configuration the product is powered direct from the
usb port, removing the need for additional power. If the user wishes to monitor live process data during configuration, then power must be applied. Note the input and USB port of the
device share the same ground, therefore care must be taken to ensure isolation between PC and input circuit. This is best achieved by using a portable laptop or notebook PC.
USB_Speed_Link software is provided with detailed help menu to guide the user through the simple configuration procedure. Unless specified at the time of order this product is
supplied with the default configuration listed below.

SH BUTTON CONFIGURATION
Two trim buttons are provided on the front panel – blue = low trim, red = high trim. The trim buttons allow the operator to trim the device against a live input signal (similar to
the “Active Range” range buttons available in the configuration software). The trim buttons operate as follows, please note both trim points operate independently, if desired
only one trim point may be set, for example the low (blue) to correct a zero offset :With the input settled at the required high or low trim point, press and keep button pressed - the range light will go off for a few seconds then flash at a fast rate before
returning to a steady state. Release button. Trim operation complete. Output trims to levels preset in the software configuration.
The tare may be set remotely by using contacts 9 and 12 connected to a volt free contact. The actual tare setpoint can be pre-programmed into the device during
configuration.
On tare contact closure corrections within the device in the form of a offset to set the present input signal to represent the preset tare setpoint value.
