4.6.2 Clear Time Settings

The following settings are available through the InfraWin software or by using the UPP data

format commands.

OFF When set to OFF, the maximum value storage is switched off and all new

temperature values are measured but not stored.

10 ms…25,0 s If the clear time is set between 10 ms and 25.0 s, the maximum value is

held in double storage mode. After the entered time, the value will be

cleared alternately from one of the storages, while the value of the other

storage is shown.

EXTERN

With the external clearing function, the storage operates in single storage

mode. The values are immediately cleared from the storage by contacting

the wires connected to pins J and K, if the EXTERN mode was selected.

AUTO The AUTO mode is used for discontinuous measuring tasks. For example,

when objects are being transported on a conveyer belt and pass the

measuring beam of the pyrometer only for a few seconds. In this case, the

maximum value for each object has to be obtained.

With the AUTO mode, the maximum value is stored until a new hot object

appears in the measuring beam. The temperature, which has to be

recognized as “hot” is defined by the low limit of the adjusted sub range.

The stored maximum value will be deleted once the temperature of the new

hot object exceeds the low limit of the sub range by 1% (transition in

positive direction) or by at least 2 °C. This is also valid if the sub range equals

the basic range.

HOLD The HOLD function allows you to freeze the current temperature reading at

any moment. This feature is activated using an external switch that has been

connected between connector pins J and K.

The temperature reading will remain frozen as long as the contact remains

closed.

4.7 Analog Output

The analog output has to be selected according to the signal input of the

connected instrument (controller, PLC, etc.). If 4 to 20 mA is set, the analog

output gives 3.9 mA for temperatures below lower range limit.

4.8 Sub Range

You have the opportunity to choose a sub range (minimum span 50 °C) within the basic

measuring range of the pyrometer. This sub range corresponds to the analog output.

Example: Range 150…1800 °C, Sub Range 925…975 °C.

The sub range setting also affects the maximum value storage when the Clear Peak Memory

clear

is set to AUTO. For more information on the t

clear

AUTO setting, refer to section 4.6.

Note: Settings for Sub Range - any range adjustable within the temperature range

with a minimum span of 50 °C.
