13 Eliminating faults and malfunctions

Example 2

The measuring transmitter is to show 500 mS:

To achieve a display of 500 mS/cm, the resistance loop (with 3 turns) must
have a resistance of 112.5 Ohm.

Precalculated
values

Test
sequence

✱

Calculate the test resistance.

✱

Wire up the device, see Chapter 7 "Installation", Page 25.

✱

Select the corresponding measurement range, see Chapter 10.6.1
"CONDUCTIVITY IN (Conductivity input)", Page 37 -> RANGE 1 — 4

✱

Set TC to 0%/°C, see Chapter 10.6.1 "CONDUCTIVITY IN (Conductivity
input)", Page 37 -> TEMPCO

✱

Fit the resistance loop as shown in the diagram.
