Notes:

1. This is a 0-1 volt d.c. output where 0 volts corresponds to 0% torque and

1 volt corresponds to 100 % torque with a resolution of 1 millivolt (0.1%).

2. This is a 0-4 volt d.c. output where 0 volts corresponds to -100°C and 4 volts

corresponds to +300°C with a resolution of 1 millivolt (0.1°C).

Analog Output:

The analog outputs for temperature and % torque are accessed from the 9-pin connector located on

the rear panel of the DV-III Ultra. The pin connections are shown in Figure I-1. The output cable

(Part No. DVP-96Y) connections are:

Red Wire: Temperature Output

Black Wire:

Temperature Ground

White Wire:

% Torque Output

Green Wire:

% Torque Ground Note:

Please contact Brookfield Engineering Laboratories or your local dealer/distributor for purchase of

the DVP-96Y analog output cable.

See Appendix D to perform the appropriate calculations using the data acquired during a test.
