Dual sensor differential measurements will have similar accuracy

speciﬁcations.

To access Dual Module Functions:

Press MENU key

Use DOWN or UP ARROW to highlight “Modes…”

Press ENTER

Use DOWN or UP ARROW to highlight “Dual module functions…”

Press ENTER

Press DOWN or UP ARROW to highlight “Differential CH1-CH2”,

“Differential CH2-CH1”, or “Additive (CH1+CH2)”

Press ENTER

Display will show a single value indicating desired pressure

calculation.

The HHC can be used with most standard RTD (Resistive Tem-

perature Detector) probes to provide precision temperature mea-

surements. An XXX –RT1 or XXX –RT2 Quick-Select module

is needed to interface an RTD probe to the HHC. There are two

XXX -RT Quick-Select module types available to support RTD

resistance levels and capabilities indicated in the table below:
