Factory Options
To wire in the analog output board, a shielded 22 gauge, 3-conductor wire
(P/N 73041) is recommended, with the maximum length being 50 feet
(15.2m). This wire is readily available from other vendors including Alpha
P/N 2403 and Deerborn P/N 972203.

Caution Accuracy of the output at the board terminal strip to the
incubator display is ±1 unit. There is no calibration from the incubator.
Calibration to the incubator display must be at the instrument connected
to the output board.
