1.0 Introduction
ETC-calibrators are temperature calibrators designed to calibrate
temperature sensors.
Read this manual carefully before using the instrument and make
sure that all safety instructions and warnings are observed.
2 123943 03
2.0 Safety instructions
Read this manual carefully before using the
instrument!
In order to avoid any personal injuries and/or damage to
the instrument all safety instructions and warnings must be
observed.
Disposal – WEEE Directive
These calibrators contain Electrical and Electronic circuits
and must be recycled or disposed of properly (in
accordance with the WEEE Directive 2002/96/EC).
Warning……
About the use:
• The calibrator must not be used for any purposes other
than those described in this manual.
• The calibrator has been designed for interior use only
and should not be used in hazardous areas, where
vapour or gas leaks, etc. may constitute a danger of
explosion.
• The calibrator must be kept free within an area of 20
cm on all sides and 1 metre above the calibrator.
• Never use heat transfer fluids such as silicone, oil,
paste, etc.
These fluids may penetrate the calibrator and cause
damage or create poisonous fumes.
123943 03 3
About the insertion tubes:
• Never leave hot insertion tubes which have been
removed from the calibrator unsupervised – they may
constitute a fire hazard.
Caution – Hot surface
• Do not touch the well, the insertion tube or the grid
plate, as the calibrator is heating up / has been heated
up – they may be very hot
• Do not touch the tip of the sensor when it is removed
from the insertion tube/well – it may be very hot.
4 123943 03
Caution…
About the use:
• Do not use the instrument if the ventilator is out of
order.
About the well, insertion tube and grid plate:
• The well and the insertion tube must be clean before
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.
• The insertion tube must always be removed from the
calibrator after use.
The humidity in the air may cause verdigris on the
insertion tube inside the instrument. There is a risk that
the insertion tube may be stuck if this is allowed to
happen.
Note…
The product liability only applies if the instrument is
subject to a manufacturing defect. This liability becomes
void if the user fails to follow the instructions set out in this
manual or uses unauthorised spare parts.

• The calibrator is designed for interior use only and
should not be used in risk-prone areas, where vapour
or gas leaks, etc. may constitute an explosives hazard.
• Never use heat transfer fluids such as silicone, oil,
paste, etc.
These fluids may penetrate the calibrator and cause
damage or create poisonous fumes.
• The calibrator must be kept clear within an area of 20
cm on all sides and 1 metre above the calibrator.
