Note: The AREX 5 Digital always has primary control of the heating plate temperature. The temperature control
feature of the heating plate can also be used as a safety thermostat. In this case, the maximum temperature of the
heating plate will not exceed the temperature setting on the magnetic stirrer (see option
meaning that a longer heating time is required in order to reach the VTF thermoregulator temperature setting, thus
reducing temperature oscillation at a setpoint value.
Operation with external probe
•
Turn off the instrument using the main switch
•
Screw the threaded support rod into its seat on the back of the instrument (optional)
•
Fasten the clamp onto the support rod (optional)
•
Place the external temperature probe into the clamp (optional); then place it into the sample contained inside the
flask
•
Plug the probe into the dedicated socket on the back of the instrument. The AREX 5 Digital automatically recognize
the type of temperature probe (Pt100 or Pt1000)
•
Turn the unit on using the main switch. When the external probe is connected correctly, the Probe led is on
•
Turn the left knob to set the working temperature; the Set led indicates that the display is showing the set point
temperature
•
Push the left knob to start heating. The left display shows the temperature read by the probe for 3 seconds and the
setpoint for 1 second
