b) Connecting the power supply (optional)
• The power supply must provide a stabilised voltage of 9 V/DC and a current of at least 300 mA.
• The DC barrel plug must have the following specifications:
- Outer diameter 5.5 mm
- Inner diameter 2.5 mm
- Polarity: Inside positive pole, outside negative pole.
• To connect the power supply, open the side cover (19).
• Insert the DC barrel plug of the power supply into the "DC 9V" socket.
• Connect the power supply to a common household wall socket.
The socket must be nearby and easily accessible.
• After completion of the measurement, disconnect the power supply from the meter and close the cover.
9. Setup
a) Connecting the light sensor
• When connecting the light sensor, make sure that the meter is turned off.
Only the light sensor may be connected. An inserted temperature sensor must be removed in
advance.
• Insert the light sensor connection plug (21) into the sensor socket (1) on the meter, observing the correct polarity.
The flat side of the plug should thus face the back of the meter.
b) Connecting the thermocouple
• The meter is designed for connecting an optional thermocouple of type K and type J.
Only the temperature sensor may be connected. An inserted light sensor
must be removed in advance.
• Insert the optional temperature sensor connection plug into the thermocouple socket (12)
on the meter, observing the correct polarity. Both plug-in contacts of the thermocouple
have a different width and can only be inserted with the correct polarity. Connect the
sensor as shown.
