Performance verification test
Parameter verification procedure is described in the chapter. Verification procedure is based on
measuring resistance on the simulator output terminals with standard multimeter in recommended
points.
Required equippment
Ohm-meter nominal accuracy 0.001% in range 1
to 1.2 M
(type Fluke 8508A or similar)
RTD simulator setting
Switch RTD simulator to the resistance function. Connect standard multimeter to the simulator output
terminals. Use four-wire connection technique.
Procedure
Use following procedure to perform parameter verification test:
1.
Switch both instruments on and let them for 1 hour stabilise in the laboratory with ambient
temperature 23
3
o
C. Connect simulator terminals R4W to the standard ohm-meter (multimeter).
2.
Case of the simulator should be grounded or connected to the Lo terminal of multimeter.
3.
Check resistance value in points according to Table I.
