SCXI-1303 Terminal Block Calibration Procedure
Verification Procedure
This section contains step-by-step instructions for verifying the
performance of the temperature sensor on your SCXI-1303 terminal block.
Verifying Temperature Sensor Performance
Complete the following steps to verify the performance of the temperature
sensor on your terminal block:
1.
Connect a +5 VDC power source to the terminal block.
a.
Hold the terminal block vertically upright and view it from the
rear. The terminals on the 96-pin DIN connector are designated
as follows:
–
Column A is on the right, Column B is in the middle, and
Column C is on the left.
–
Row 1 is at the bottom and Row 32 is at the top.
Figure 1 illustrates the connector pin assignments. Individual pins
are identified by their column and row. For example, A3 denotes
the terminal located in Column A and Row 3. This conforms to the
labeling of the pins on the front connector of a mating SCXI
module. It does not necessarily correspond to the labeling of the
pins on the rear of the terminal block connector itself, which you
can only view by opening the terminal block enclosure.
b.
Strip 0.5 inches of insulation from one end of a 22 AWG solid
wire. Insert the stripped end of the wire into terminal A1 on the
96-pin female DIN connector on the rear of the terminal block.
Attach the other end of this wire to the positive terminal of the
+5 VDC power supply.
c.
Strip 0.5 inches of insulation from one end of a 22 AWG solid
wire. Insert the stripped end of the wire into terminal A2 on the
96-pin female DIN connector on the rear of the terminal block.
Attach the other end of this wire to the negative terminal of the
+5 VDC power supply.
