Subrange (from / to)

You have the opportunity to choose a subrange (minimum 51°C) within the basic measuring range of the
pyrometer. This subrange corresponds to the analog output. "from" describes the beginning of this measur-
ing range, "to" the end of the range.
Additionally with the setting of a subrange it is possible to fulfill the requirements of the "auto" clear mode of
the maximum value storage (see above).
9.6

Address (Adr)

For the connecting of several pyrometers with RS485 with one serial interface it is nec-
essary to give each instrument an individual address for communication. First it is nec-
essary to connect each single instrument to give it an address. After that all instruments
can be connected and addressed individually. If parameters may be changed simulta-
neously on all pyrometers, the global Address 98 can be used. This allows you to program all pyrometers at
the same time, regardless of the addresses that have already been assigned. If the address of a pyrometer
is unknown, it is possible to communicate with it using the global Address 99 (connect only one pyrometer).
9.7

Baud rate (Baud)

The transmission rate of the serial interface in Baud (Bd) is dependent on the length of
the cable. A standard cable length with RS232 for 19200 Bd is 7 m, with RS485 2 km.
The baud rate is reduced by 50% if the transmission distance is doubled.
9.8

Temperature display (C / F)

The temperature can be displayed in °C or °F.
9.9

Wait time (tw)

Using a pyrometer with RS485 it is possible that the connection is not fast enough to
receive the pyrometer's answer to an instruction of the master. In this case a wait time
can be set to slow down the data transfer (e.g.: tw = 02 at a baud rate 9600 means a
2
wait time of / sec).
9600
9.10

Maximum internal temperature (MaxIntTemp)

Shows the maximum internal temperature the device ever reached.
9.11

Error status (Status)

In case of a device error the pyrometer displays a hex code which identifies this error to LumaSense ser-
vice. The standard display at this point is "ok".
