This menu is used for configuring the Pt resistance thermometer
calibration.
To calibrate Pt resistance
thermometers, the respective
type of thermometer and
connection is selected with the
cursor keys and confirmed with
the SELECT key. The
connection is established
exclusively via the binding
posts.
Binding posts
The binding posts are suitable for connecting blank wire ends,
spade connectors lugs and 4 mm banana plugs. Take the required
wiring technology into consideration for establishing connections.
There are three possibilities:
„
2-wires: terminals 2 + 3
„ 3-wires: Terminals 3 + 4 loop, 2 + 3 Pt resistance
„
4-wires: Terminals 1 + 2/3 + 4 loop, 2 + 3 Pt resistance
Interchanging the connectors results in measurement faults.
