6. The display and the operating devices
6.1. The first start-up
The dispay is shown by the arrow (1).
After the apparatus has been installed to its place, the
probe Pt100 has been connected in accordance with the
specified mode, and the connection to the measurement
loop has been established, then the display of the
apparatus shows the measured temperature values with an
accuracy of the decimal of the degree. Accordingly, if the
temperature is 24.2 degrees centigrade, the following is
visible on the display:
If it is 123.7 °C, then:
As the factory default setting of the apparatus is 4 wires for
Pt100 connection, the displayed value will be accurate in
that case only if actually 4 wires are used for the
connection. If a 3-wire physical connection is used, the
setting of the apparatus must also be changed to this mode,
in order to ensure accurate measurement (Chapter 7.2,
menu 04)
If something else appears on the display instead of the
measured temperature values (a message written by
blinking letters), then it is an error message of the apparatus
DT9502.
In order to identify the fault, go to the Appendix at the end of
this Operating Instructions, and see chapter 10.3 Error
messages or 10.4. Messages of critical errors.
