Digital Ground
The ground level from the analyzer’s internal DC power
supplies. This connection should be used as the
ground return when +5VDC power is used.
CONNECTING THE CONTROL INPUTS (DIGITAL INPUTS)
With zero and span valves option installed, two digital control inputs in the rear panel
CONTROL IN connector, can be used to remotely activate the zero and span calibration
modes (see Section 4.2.2.1).
Energize the Control Inputs either by the in5V available from the pin labeled “+”
(more convenient), or by a separate external 5 VDC power supply (ensures that these inputs
are truly isolated). Refer to Figure 2-7.
