6.10 Temperature Sub Range

The temperature range can be scaled down in order to adapt it to specific measurement conditions
(minimum range 51°C), e.g. to configure the automatic clear function of the maximum value storage
(see 6.9). A modified temperature range also can be set for the analog outputs to increase the resolu-
tion even further.

6.11 Customize Analog Output

The analog outputs can be set independently of the temperature sub range. They can be set to range
limits between 0 and 6000°C or °F, even if the pyrometer does not cover these ranges.
 Limit the analog output: if the analog output is set smaller than the pyrometer's temperature range,
the resolution of the analog output is increased even further.
 Enlarge the analog output: Entering a larger range as the pyrometer's range will scale the output
according to that larger range, with the limitation that the current output at the beginning of the py-
rometer's temperature range is 0 or 4 mA, at the end of the range the current is hold that would be
present in the selected area .
Example: A pyrometer with temperature range 750–2500°C
should be adapted to the range 600–3000°C. In the range
of 600–750°C, the pyrometer cannot measure yet; it shows
in the software "Under". At the analog output (e.g. set to 0–
20 mA) the output current is 0 mA as long as 750°C is
reached, then 1.25 mA will be set to the output. Same with
the upper limiting temperature, from 2500°C the current is
consistently issued, a 600–3000°C device would display at
2500°C.

6.12 Temperature Unit

The temperature display can optionally be displayed in °C or °F.

6.13 Analog Output

The 2 analog outputs can be set separately:
 Depending on the connected devices to 0–20 mA or 4–20 mA
 Analog output 1 always provides the measured temperature (always the temperature, displayed on
the device or in the software control window; see also
(Note: With older firmware versions, the same settings are possible as at analog output 2. A firmware
update to the latest version eliminates this possibility and prevents, that the output of analog output 1
is accidentally different to the displayed temperature signal. Firmware update see section 8).
 Analog Output 2 can be assigned to provide different signals:
- Flame temperature:
- 2-color temperature:
- Temperature channel 1: Channel 1 temperature output
- Temperature channel 2: Channel 2 temperature output
- Sum temperature:
- Device temperature:
- No output
portant temperature information can be lost at sinking temperatures).
The maximum value is manually generated via an external button or machine contact,
as long as the trigger contact is active. The maximum value display appears after re-
leasing the button.
