METIS M311 / M322 / H311 / H322 (12-pin device connector)

7.1.5.3 Device display

Enables or disables the measurement temperature display.
Measurement temperature activated: shows
the measured temperature on the display.
Suppressed:
▪ Devices with OLED display: display is switched off.
▪ Devices with LED display: shows lines over the en-
tire display instead of the temperature display.

7.1.5.4 Device Language

Changes the language of the parameter menu on the device to English or German.
7.1.5.5

Keylock

To lock or unlock the key functions on the device (enabling on the device, see 6.1).
▪ None: All functions can be changed using the buttons on the unit.
▪ Active: The buttons on the unit are disabled.
▪ Menu lock: activates an input field for a 4-digit PIN code, which enables to protect changing of parameters
(PAR key) on the device. If activated, this code must be entered on the device before parameters with the
PAR button can be changed.

7.1.5.6 Analog Outputs

▪ Output mode sets the output current to 0...20 mA or 4...20 mA.
▪ Output temperature
- Analog output 1 always provides the measured temperature, which is shown on the device display or in
the SensorTools
- Analog output 2 (will be displayed after expansion with
you can select which output signal should be provide:
- The ratio temperature or that of each channel can be set assigned to the output.
- Device temperature is the internal pyrometer temperature (scaled from 0 to 100°C).
- Controller output: The manipulated variable at devices with a PID controller is set here as standard.
- "No output" disables the analog output.
▪ Test can be used to set a test current at the respective output (see
Further adjustments can be made by extending the setting range.
▪ Adaptation: The analog outputs can be scaled between 0 and 6000°C to adapt them to special circum-
stances, e.g. to replace for a device with a larger temperature range or to obtain a higher output resolution
(see 6.2.10.3).
With the reset button, the temperature range is set to the adjusted temperature sub range.
▪ Output options
- If the beginning of the temperature range is reduced under "Adaptation" in order to scale the analog out-
put, a decision must be made what should happen below the beginning of the pyrometer temperature
range, since the pyrometer cannot measure from the lowered beginning value to the beginning of the py-
rometer temperature range.
- Scaled current below ZSC outputs a constant current equal to that of the extended temperature range
until the pyrometer's lower range value is reached.
- 0/4mA below ZSC (only available with M3, not with H3) outputs 0 mA or 4 mA until the beginning of
the pyrometer temperature range is reached, depending on whether the output is set to 0-20 mA or 4-
20 mA is.
