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