Important Measuring Parameters
■ Emissivity set Ԑ: the emissivity indicates the surface characteristics of the measured material and must be entered into the
pyrometer to get correct measurement results (an emissivity table can be found in the operating instructions).
■ Response time t
: Short setting enable the fastest measurement. At longer response times, the measurement signal is
90
smoothed and average values for temperature fluctuations are formed caused by the inertial measurement.
■ The storage mode is turned on when the peak value, minimum value or the average temperature of the current measurement
is to be captured and displayed or used via the outputs.
■ If a viewing window is located between the measuring object and the pyrometer, the transmittance of the window must be con-
sidered during the measurement. Enter the transmittance of the window in order to obtain a correct measurement result.

Connecting Analog Devices
The pyrometer has 2 separate analog outputs for connecting
additional evaluation devices:
■ Adjustable to 0-20 mA or 4-20 mA
■ Analog output 1 always provides the measured temperature
■ To analog output 2 can be assigned, except of the mea-
sured temperature, the device temperature or the manipulat-
ed variable for devices with PID controller.

Configure Inputs / Outputs
3 via software SensorTools configurable inputs / outputs are
each available as:
■ Digital output: output of a switching signal (50 mA) at differ-
ent temperature events
■ Digital input: switch device functions externally via an input
voltage pulse.
■ Analog input (only M3): adjust via external 0–20 mA
the emissivity, the setpoint (when equipped with a PID controller) or the measuring distance (at motorized focus optics)

Use of the Serial Interface
The serial interface is used for digital communication with a
computer, for example via the included software SensorTools.
■ RS232: Baud rate 4.8–115.2 kBd for a short direct connection
■ RS485: Baud rate 4.8–921.6 kBd for direct connection or bus
operation with up to 32 devices
The pyrometer can be connected to a PC with USB port via a
USB interface converter (recommended accessory).

SensorTools Software (min. Windows 7)
All pyrometer settings can
be adjusted via software
when a PC connection is
established via the serial
interface port (for exam-
ple, via an USB interface
converter).
Functions such as the
configuration of the inputs /
outputs can only be carried
out via software.
In addition, the mea-
surement value trend is
displayed numerically and
graphically and can be
recorded.
With connected pyrometer
the device keys are locked.
"KEY LOCK" appears when
pressing a key.
About SensorTools, the pyrometer can be updated to a new firmware version to fix bugs or add new features. SensorTools including
the latest firmware can be downloaded from the website at www.sensortherm.de/en/download-section (given by entering the model
number (first 4 characters) and serial number required).
