Starter System Setup
Figure 12 illustrates the jumper setup on Multi-Cal-Test PCA card. The Multi-Cal-Test PCA has seven
jumpers that allow you to choose between three different modes of operation (current output, four-wire
voltage output, and three-wire voltage output). The Multi-Cal-Test PCA card also has two banks of
jumpers that select the sensor-emulator output on the test board.
SensorEmulator switch (SW1).
Selects between High bank and
Low bank. Here, Low bank is
selected.
Jumper banks for
sensor emulator. Select
one of the five positions
for each bank. Here.
Low = 6mV, High = 3mV.
Seven jumpers used to select
the PGA308 mode. Here, 4-wire
Voltage Output is selected.

Table 3 and Table 4 explain how to set the jumpers on the Multi-Cal-Test PCA and the respective jumper
functions. The test board allows all for the operation of the three modes of the PGA308 device. The test
board also has a jumper-selected sensor-emulator. The sensor-emulator creates an input signal for the
PGA308 so that you can perform an example calibration.
