b.

Connect a test connector adapter to 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.

Connect a test connector adapter to 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.

2.

Connect a calibrated DMM to the temperature-sensor output of the
terminal block.

a.

Refer to Figure 2 to locate jumper W1 and verify that MTEMP
is jumpered on the terminal block.
