IMPAC pyrometers IN 140/5 · IN 140/5-H · IN 140/5-L
10.12
PC sampling rate (time interval between two measurements)
This function sets a time interval. After each interval one
measured value is stored on the PC. The bigger the time
interval the smaller will be the stored file. This function is
mainly used for long term measurements.
10.13
Spot size calculator
The spot size calculator is only used for pyrometers with fixed optics. After input of the aperture and
the main spot size, the input of interim values it calculates spot sizes in different measuring dis-
tances of the fixed optics.

Transport, packaging, storage
The instrument can be damaged or destroyed if shipped incorrectly. To transport or store the instrument,
please use the original box or a box padded with sufficient shock-absorbing material. For storage in humid
areas or shipment overseas, the device should be placed in welded foil (ideally along with silica gel) to pro-
tect it from humidity.
The pyrometer is designed for a storage temperature of -20 to 70°C with non-condensing conditions. Other
kind of storage can damage or malfunction the pyrometer.

Maintenance
12.1
Safety
Attention during pyrometer services:
Should the pyrometer be integrated in a running machine process the machine should be switched off and
secured against restart before servicing the pyrometer.
12.2
Service
The pyrometer does not have any parts which require regular service, only the lens has to be kept clean.
The lens can be cleaned with a soft cloth in combination with alcohol (do not use acid solutions or dilution).
12.3
Optics replacement
The lens of the optics of the IN 140/5 can be replaced by only ex-
actly the same lens (e.g. 1-N by 1-N) without recalibration of the
instrument. The change of the lens for other measuring distances
can only be done at LumaSense Technologies as this change re-
quires a new calibration. A replacement can be necessary if the
lens is scratched or damaged or the pyrometer will be used for
other measuring distances.
Replacement:
For replacement of the lens the fixing ring has to be unscrewed with a suitable objective wrench. After re-
moving the old lens, put in the new one with the convex side to the front. Fix the lens with the fixing ring
carefully. Please take care that the O-ring gasket is still in the position between lens and optics.
Exception: Optics 2-NL consists of 2 similar lenses and a distance ring. The convex sides of the 2 lenses
must be mounted against each other with the distance ring in between.
The lenses are color marked at their edge for differentiation:
Lens for optics 1-N:
Lens for optics 2-N:
Lens for optics 3-N:
Lens for optics 2-NL:
