Preamplifier in a junction box

The procedure is the same as described in 

Preamplifier in transmitter

. Keep the connection

between the analyzer and the junction box in place. Disconnect the sensor at the sensor
side of the junction box and connect the voltage source to the sensor side of the junction
box.

Preamplifier in sensor

The preamplifier in the sensor converts the high impedance signal into a low impedance
signal without amplifying it. To simulate pH values, follow the procedure in 

Preamplifier in transmitter

.

Simulating temperature

General information about simulating temperature

The transmitter accepts either a Pt100 RTD (used in pH, 499ADO, 499ATrDO, 499ACL-01,
499ACL-02, and 499AOZ sensors) or a 22k NTC thermistor (used in Hx438 and Gx448 DO
sensors and most steam-sterilizable sensors from other manufacturers). The Pt100 RTD
has a three-wire configuration. See 

Figure 8-14

. The thermistor has a two-wire

configuration.
