SECTION 3. Configuration
3.1 GENERAL
Set-up and calibration of the DXp-10/15 is
accomplished by an operator without
programming using the DIP switches, push-
buttons, and toggle switches within the unit.
Units connected to an LCp-40 or computer ter-
minal can be set-up and calibrated remotely via
the serial port (see Appendix E).
3.2 SET-UP
3.2.1 Power Selection
All units are shipped from the factory configured
for 115 VAC operation. To change the voltage
selection to 230 VAC, change SW1 (see Figure
2-4) to the 230V setting. The unit will operate
within specification at 50 or 60 Hz.
3.2.2 Excitation Voltage.
All units are shipped from the factory set for 10
volt excitation.
3.2.3 Serial Format, Address, and
Baud Rate.
DIP switch selections for transmitter address,
baud rate and serial interface format are
presented and defined in SECTION IV, Serial
Communication.
3.2.4 Input Range Selection.
Units are shipped configured for a 25 mV input
range. To increase this range to 35 my, remove
the jumper shunt from JP2 on the A-D converter
board as shown in Figure 3-1 (see Appendix A
photo for A-D board location).

3.3 CALIBRATION
Note: All switches mentioned in paragraphs
3.3.1
– 3.3.4 are depicted in Figure 3-1.
3.3.1 Digital Calibration.
The transmit only serial output can be digitally
calibrated using the DIGITAL selector, 1NC/DEC
and ENTER switches mounted on the DXp-
10/L5 control panel. For those systems where
applying a full capacity dead weight or input
signal is not practical, the DXp-10/15 will
automatically calculate a linear full span
calibration based on a single span point. See
Table 3-1 for instructions.
