5.11 Test Current Output (10 mA)
The test function activates a test current of 10 mA on the analog output, independently if the
instrument is adjusted to 0 ... 20 mA or 4 ... 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.
5.12 Wait Time
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 9, Data format UPP.
5.13 Switch Contact
The pyrometer is equipped with a built-in switch contact which allows you to use the pyrometer
as a thermo switch. This function enables the detection of a hot object in the measuring beam
of the pyrometer. The contact is activated only in combination with a clear time settings “auto“
or clear times ≥ 1 s (see Section 5.3 t
CL
/ s (clear times of the maximum value storage)). If
the temperature exceeds 2 °C min. or 1% of the span of the temperature sub range above the
minimum temperature, the supply voltage (pin K) is connected to pin J.
