Card Connections and Installation
2-4
1. Open the plastic shield to gain access to the connectors.
2. Strip approximately
¼
” of insulation from the end of
each wire.
NOTE
Standard thermocouple wire or #22 AWG
stranded wire is recommended for scanner
card connections.
3. Turn the screw terminal several turns counter-clockwise
until the access hole is open. Insert the wire in the access
hole.
4. While holding the wire in place, tighten the connector
screw securely.
CAUTION
Be sure not to over tighten screw termi-
nals, or the connectors may be dam-
aged.
5. Repeat steps 2 through 4 for each wire to be connected.
6. Dress input wires through the cable clamp, as discussed
in paragraph 2.3.5.
WARNING
If thermocouples are going to be floated
above 30V RMS, 42.4V peak, 60VDC,
make sure thermocouple wires have ad-
equate insulation.
2.3.4 Output connections
Use the supplied test leads for scanner output connections.
Connect red leads to the output (OUT A and OUT B) HI ter-
minals, and connect black leads to the output LO terminals.
See Figure 2-3 for details. Dress output test leads through the
cable clamp, as described in paragraph 2.3.5. After all wires
are connected and secure, close the plastic shield, and secure
it with the locking tab.
NOTE
If you intend to use the scanner card only
in the 2-pole mode, it is not necessary to
connect output leads to both OUT A and
OUT B. Use only OUT A for the 2-pole
mode.
After the scanner card is installed, the output leads must be
connected to the multimeter rear panel input jacks. See para-
graph 2.5.2 for details.
2.3.5 Dressing leads
After wires are connected to the terminal blocks, they should
be dressed through the cable clamp as shown in Figure 2-4.
To do so, unlatch the clip that holds the cable clamp together,
then route all wires flat against the lower half of the clamp.
Clamp the wires down, then secure the clamp with the metal
clip unlatched earlier.
