2. Calibrator Interface
Figure 1 shows the location of the input and output connections on the
calibrator, while Table 1 describes their use.
Table 1: Input and Output Terminals
No. Name Description
1, 2 Measure Isolated V, Input terminals for measuring current,
mA terminals voltage, and supplying loop power.
3 TC input/output Terminal for measuring, or simulating ther-
mocouples. Accepts miniature polarized
thermocouple plugs with flat in-line blades
spaced 7.9 mm (0.312 in) center to center.
4,5 Source/Measure Terminals for sourcing and measuring
V,RTD 2W, Hz, voltage, frequency, pulse train, and RTDs
6,7 Source/Measure Terminals for sourcing and measuring
mA terminals, 3W 4W current, and performing RTD measurements
with 3-wire or 4-wire setups.
8 Pressure module connector Connects calibrator to a pressure module for
pressure measurements.
9 Serial port Connects calibrator to a PC for remote con-
trol.
