6.3 Routine inspection of the equipment
(annually)
Temperature control unit
The base plate heater is checked by the user or by a BUCHI
service agent using an external temperature sensor.
For this, introduce a thermocouple Ø 4 mm (see chapter,
Replacement parts) into the hole at the side of the base plate

and check the tem pe ra ture of the base plate while it is in
a steady state condi tion:
at 50 °C, at 100 °C, and at 150 °C.
If necessary, the heater and the measurement of temperature
in the single platform can also be calibrated.
6.4 Calibration
Introduction
The user can check and calibrate the measurement of tempe-
ra ture in the heating plate of the Syncore single platform at
any time (our service agent will be happy to do the calibration
for you). The calibration takes place automatically, controlled
by the single platform.
The internal temperature measurement within the unit using
the Pt-1000 sensor built into the heating plate is compared
here with the temperature measured by an external reference
sensor. Three measurements of temperature are compared:
50 °C, 100 °C, and 150 °C.
Material needed
A reference sensor must be used to calibrate the temperature
(see chapter, Replacement parts).
A reference sensor with an unknown accuracy or an incorrect
indication of temperature can cause an incorrect calibration
of the temperature measurement in the heating plate of the
Syncore single platform.
