IMPAC pyrometer IP 140-LO
8.1

Settings at the instrument

The LC-display as well as the push buttons for
displaying and setting of the parameters are found
inside the unit. The pyrometer is opened by 4 allen
screws. If unscrewed, the rear cover can be pulled
out along with the attached display and push but-
tons. The pullout is limited by the lengths of the
screws.
The backlight of the display is always powered in
either status, opened or closed pyrometer.
Note: Please make sure that the
pyrometer is not contaminated
while open.

Key panel operation

1 PAR: With the PAR button all available parameters
are displayed in the following description
(section 10). Pushing the button again
changes the display to the next parameter
and on the display a corresponding short
form is displayed (see section 10, in brackets
behind the parameter names).
2 : With the arrow keys
settings can be displayed. Pushing the button
longer changes the settings in fast mode.
3 ESC / ENT: Pushing the ESC button changes the pyrometer to measuring mode. If a parameter is
changed with the arrow keys the indication of the ESC button changes to ENT. Pressing
the button again confirms the value into the pyrometer. Changing the parameters again by
pushing the PAR button doesn't confirm this value in the pyrometer. If no button is pressed
for 30 s the pyrometer changes to
changed value.

Selection of the serial interface

Opposite to the display
there is a switch to select
a serial interface RS232
or RS485. The LC display
shows as chosen either
RS232 or RS485.

Test function

The diagnostic push button „test" generates a current on
the analog output which is used to check if a connected
external indicator shows the correct temperature value.
The test current output is centered to the chosen analog
output span, consequently 10 mA is supplied if the ana-
log output is adjusted to 0 to 20 mA and 12 mA is sup-
plied if the analog output span is set from 4 to 20 mA.
The LC display indicates the respective current along
with the corresponding temperature. For example if a
measuring range of 100°C to 650°C is selected the
temperature shown in the display is 375°C). This tem-
perature must be reflected exactly by the indicator which
