4.13 Baud Rate
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.
4.14 Analog Test 10 mA
The test function activates a test current of 10 mA on the analog output, independently if the
instrument is adjusted to 0 to 20 mA or 4 to 20 mA. This enables to test external indicators for
correct scaling. The reading of the internal indicator should correspond to the reading of the
external indicator. If both displays show different readings the external indicator has a wrong
temperature range or input current setting. The test function is switched off automatically after
1 minute and the instrument is working in the measuring mode.
4.15 Wait time (t
w
)
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 wait time of
2
/
9600
sec).
Note:
Only available via interface commands, see chapter 7, Data format UPP).
