Note:
Route recorder cable through a separate conduit, not with power cable.
Output selection and cable connections for voltage-actuated and current-actuated
devices are explained in Sections 2.3.1 through 2.3.5.

1. On the Master Board (Figure 2-6):
a. Verify that TB2-1 is jumpered to TB2-2.
b. Set S1 for desired voltage: 5V, 1V, .1V, or .01V.
c. Connect the recorder cable to the TB4 terminals labeled VOLT OUT: TB4-1(+)
and TB4-2(-).
Note
Take the usual precautions to avoid AC pickup. DO NOT GROUND EITHER
LEAD.
2. Connect the cable to input terminals of the recorder; ensure that polarity is correct.
3. Ground shield on one end only.

2. On the Master Board (Figure 2-6):
a. Verify that TB2-1 is jumpered to TB2-4, and TB2-2 is jumped to TB2-5.
b. Set S1 for desired voltage: 5V, 1V, .1 V, or .01 V.
c. Connect the recorder cable to the TB4 terminals labeled VOLT OUT: TB4-1 (+)
