Control working - Pen arm calibration
The chart recorder is calibrated from the
factory. However, it is important to check
that the temperature trail is showing the
right temperature.
We suggest to control the recorder´s cali-
bration every 12 months.
Measure the temperature near by the
installed temperature sensor (probe) with a
reliable thermometer.
If there is a difference of +/- 2°C between
the data provided by the reliable thermom-
eter and those of the recorder, proceed as
follows:
● Gently take the pen´s arm B.
● With a small screwdriver, calibrate the
regulation screw A, until the fibre pen C
is writing the same temperature as the
reliable thermometer shows.
