7 Setup interface and fine calibration

Setup interface

The setup interface is available for configuring the transmitter from
a PC. The connection is via the PC interface with a TTL/RS232 con-
verter and adapter.
The cover flap must be closed after programming.

Configurable parameters:

- tag number (10 characters)

- sensor type

- connection circuit (2-/3-/4-wire)

- external or internal cold junction

- custom linearization

- range limits

- output signal rising/falling (inversion)

- digital filter

- response to probe break/short-circuit

- recalibration (fine calibration)

- lead resistance for 2-wire circuit

If no Ex supply unit (supply isolator) is available, the 2-wire transmit-
ter can also be configured using a 9V block battery.

Fine calibration

Fine calibration means adjustment of the output signal. The signal
can be adjusted within ± 5% of the 20mA end value. Fine calibra-
tion is performed using the setup program. Values for 4 mA (zero
point), 20 mA (full scale) and offset can be calibrated separately, us-
ing the setup program.
