Scale °C or °F:
The LED indicates the temperature scale in °C or °F.
Parameter indicator: LED’s indicate which pyrometer parameter is selected for reading or changing.
Push button for test
current:
The test button activates a test current of 10 mA on the analog output, independent if
the instrument is adjusted to 0 ... 20 mA or 4 ... 20 mA. This enables to test external
indicators for correct scaling. The readings of the internal indicator should corre-
spond to the reading of the external indicator. If both displays show different read-
ings the external indicator has a wrong temperature range or input current. This test
current can be switched off by pushing the test button again or any other setting key
or it is switched off automatically after 30 seconds and the instrument is working in
the measuring mode.
LED for
clear mode: LED indicates if the maximum value storage is operating in automatic or external
clearing mode.
Temperature or
parameter display: In the measuring mode the display shows the actual temperature reading. After
pushing the parameter key the display indicates the actual value of one selected
parameter.
Special indications: see 8.2
Measuring mode
display LED 1 = mono mode
LED 1 and 2 = ratio mode
LED M = metal mode
Setting keys: PAR:
:
ENT:
With the PAR button all available parameters are displayed in the following descrip-
tion. Pushing the button again changes the display to the next parameter, after the
last parameter it changes to the actual temperature reading.
With the arrow keys and all parameter settings can be displayed. Pushing the
button longer changes the settings in fast mode (the keys and ENT are blocked
if the keyboard is locked via the interface commands or/and during a measurement
in combination with a PC and InfraWin).
If a parameter is changed with the arrow keys the new value must be confirmed by
pushing the ENT key. If it is not confirmed with ENT the instrument is still operating
with the previous parameter value. If no key is pressed for approx. 30 s the display
changes to the temperature indication.
Targeting light
on / off: Pushing the PL key in measuring mode the laser targeting light is switched on.
The IGAR 12-LO measures continuously also with switched on targeting light and
the display shows the actual temperature reading. As the laser targeting light influ-
ences the measurement of the ISR 12-LO the last measured value is hold in the
analog output. The display shows during this time the intensity of the relative signal
(see also 10.8 Measurement color bar). In mono mode the display shows a blinking
“8000”. The laser targeting light is switched off automatically after approx. 2 min or
after a further push of the PL key.
Serial interface: Switch for selection of RS232 or RS485.
