Additional measurement uncertainty
Table 7
lists additional uncertainty to the published specifications for the Model 7708. Other modules, such as the Model 7700
(which measures thermocouple temperature), are also affected by this heat but are still within published specification. The
amount of uncertainty is dependent on:
• Model 7711/7712 slot location
• The amount of time the channel is programmed as an output
• Which other model 77XX module(s) are being used
The listed uncertainty in
Table 7
as input or off, there will be approximately 25 percent reduction in the listed on uncertainty.

Notes:
1. The above listed uncertainties are guaranteed by design for thermocouple types J, K, N,
T, E, R, S, B.
2. When the Model 7711/7712 and Model 7708 are used together, the Model 7711/7712
must be installed in the lowest numbered slot.
For example: Model 2700/2701: 7711/7712 in slot 1, 7708 in slot 2
