Figure 2. Termination check.
(8) Using multimeter, measure ohms. Multimeter indication will be within the
limits specified in table 3. Record the measured value as actual termination resistance
in ohms.

(9) Calculate the termination correction factor using the formula below:
[0.5] / [actual termination resistance / (actual termination resistance + 50)]
example
[0.5] / [49 / (49 +50)]
[0.5] / [49 / (99)]
[0.5] / [0.4949] = 1.01 = Termination correction factor
(10) Record the termination correction factor in table 4, 5, 6, and 7.
(11) Setup multimeter to measure V dc.
(12) Connect TI 9211 module OUTPUT (upper BNC connector) to the open end of the
BNC tee adapter on the front of the multimeter.
(13) Press TI pushbuttons as listed in (a) through (f) below:
(a) CHANNEL A.
