3.1 General

The EE431 duct and immersion sensor reliably measures the temperature (T) in air and liquids. It is optimized for
building automation, HVAC and process control. The measured data is available at the voltage or current output,
on the RS485 interface with Modbus RTU or BACnet MS/TP protocol and on the optional display. The analogue
output can be set to °C or °F. In addition, the EE431 features a wide choice of sensing elements for passive
temperature measurement.

▪ Modbus protocol in the register 1 (0x00) and 2 (0x01).

See Application Note Modbus AN0103 (available at www.epluse.com/ee431).

The measured values are saved as 32 bit float value (FLOAT32) and 16 bit signed integer (INT16). The factory
setting for the Modbus address is 66 as an INT16 value. This address can be changed by the user in the register
1 (0x00), permitted values are 1...247.

The serial number as ASCII-code is located in read-only registers 1 - 8 (0x00 - 0x07, 16 bits per register).
The firmware version is located in register 9 (0x08) (bit 15...8 = major release; bit 7...0 = minor release). The
sensor name as ASCII-code is located in read-only registers 10 - 17 (0x09 - 0x11, 16 bits per register).

NOTICE

When reading the serial number or the sensor name, it is always necessary to read all 8 registers, even if the
desired information requires less.

NOTICE

For obtaining the correct floating point values, both registers have to be read within the same reading
cycle. The measured value can change between two Modbus requests, exponent and mantissa may get
inconsistent then.

6 Maintenance and Service

6.1 Calibration and Adjustment

6.1.1. Definitions

Calibration: The specimen is compared with a reference and its deviation from the reference is documented.

Adjustment: The specimen is brought in line with the reference.

6.1.2. Temperature Calibration and Adjustment

Measured value

(or last calibration point LOW)

Depending on the application and the requirements of certain industries, there might arise the need for periodical
temperature calibration or adjustment.

6.1.3. Calibration and Adjustment at E+E Elektronik

Calibration and/or adjustment can be performed in the E+E Elektronik calibration laboratory. For information on
the E+E capabilities in ISO or accredited calibration please see www.eplusecal.com.

6.1.4. Calibration and Adjustment by the User

Depending on the level of accuracy required, the temperature reference can be:

▪ Liquid bath calibrator
▪ Dry block calibrator
▪ Climate chamber
▪ Handheld device (e.g. Omniport30), please see www.epluse.com/omniport30.

Perform offset and 1- or 2-point adjustment via the E+E Product Configuration Software (see below).
