To be able to use the lid for calibration, holes must be drilled in to it, in
order to fit your calibration needs. If you use many different sizes of
sensors more lids can be purchased at your JOFRA supplier.
It is advisable to drill the holes at the same size as the sensors plus
0,5mm and distribute the holes evenly over the lid.
3.3.4 Inserting the sensors
Be sure that the sensors can be calibrated in fluid. E.g. certain ceramic
sensors might be destroyed.
Caution…
The well and the insertion tube must be clean before
use.
Scratches and other damage to the insertion tubes
should be avoided by storing the insertion tubes
carefully when not in use.
The insertion tube must never be forced into the well.
The well could be damaged as a result, and the
insertion tube may get stuck.
Carefully wipe off all silicone oil from the sensor-under-
test to avoid spreading of the silicone oil.
Caution – Hot surface
Do not touch the lid or the spill tray when the calibrator
is heating up – they may be very hot and cause burns.
Do not touch the tip of the sensor when it is removed
from the well – it may be very hot and cause burns.
Do not touch the handle of the calibrator during use –
it may be very hot and cause burns.
Do not remove the insert from the calibrator before the
insert has cooled down to less than 50°C/122°F.
