4.1 Metal block ca

librator

Insertion sleeves with one or more boreholes are used for the calibration of straight temperature
sensors.

In order to achieve the best possible accuracy, the utilization of exactly fitting sleeves is
necessary.
The diameter of the test specimen has to be determined precisely. The bore in the sleeve results
from the addition of +0.5 mm.

Before use:

 Using the sleeve changing tool, fit the

appropriate insertion sleeve in the block of
the calibrator.

After use:

 Remove the sleeves after use with the aid of

the sleeve remover, and remember to clean
the sleeve and the block.
This prevents the sleeves becoming jammed
in the heating block.

A special infrared insertion sleeve is used for contactless infrared thermometers to enable fast,
easy calibration.

The hollow and specially constructed insertion sleeve is fitted
with two additional boreholes - for precise monitoring of the
temperature - in the rim (1 x 3.5 mm und 1 x 4.5 mm).

Before use:

 The insertion sleeve is inserted into the block with the aid

of the sleeve remover.

After use:

 Remove the sleeves after use with the aid of the sleeve

Using Test Specimen Fixtures

The special construction and surface condition of the sleeve is such that it reaches emissivity of 1
(black body). When using an infrared insertion sleeve, the measuring spot of the pyrometer to be
calibrated may, under no circumstances, be larger than the diameter of the infrared sleeve.

FORMATION OF ICE AND DEW!
At temperatures < 0 °C (32 °F) and higher humidity levels ice or condensation can form in the

insert sleeve. This can result in the calibration of the infrared thermometer being distorted.
The forming of ice or condensation can be significantly reduced by covering the measuring

opening of the insert sleeve.

 Keep the measuring opening closed for as long as possible.
 Only open the measuring opening briefly for measuring.



Always unscrew the transport cover before putting the micro calibration bath into service,

in order to avoid excessive pressure.

The micro calibration bath is used for calibrating sensors with special shapes or dimensions.
Direct contact between the sensor and the calibration liquid ensures excellent heat transfer. The
magnetic stirrer ensures a uniform temperature distribution in the calibration liquid.

The calibration liquid is poured directly into the tank or into a tub insert.
Tub insert:

We recommend using a tub insert if you

• frequently work with different calibration liquids.

Use the sleeve changing tool, fit the tub insert in the block.
Just like the tank, the tub insert can be closed with the associated cover. Both

threaded covers are leakproof, so the calibration liquid can be left in the tank or
the tub insert during transport.

4.3.1
Different calibration liquids supply varying calibration results due to their specific characteristics.

Adjustment to the respective calibration liquid has to be carried out by the manufacturer.
In order to achieve the best possible accuracy of a micro calibration bath, it has to be filled with a

suitable calibration liquid.

max. Filling level 136 mm

4.3.2 Information on filling amounts

CAUTION! Risk of incorrect measurement or material damage
Do not exceed the maximum fill level during operation.

Above the maximum fill level the heat dissipation is too great, preventing compliance with
the specified tolerances.
Overflow of the calibration liquid causes contamination and can damage the calibrator.

.



Ensure that the maximum fill level is not exceeded during operation.

The fill level in the tank or tub insert rises as a result of:

Thermal expansion
Calibration liquids expand to varying degrees as a
result of heating. The increase in fill level depends
on the calibration liquid that is used and the
reference temperature setting.

Displacement by sensors
The volume displaced by the sensors being
calibrated must be taken into account in the filling
amount.

Rise due to stirring
The rotation of the magnetic stirrer forms a
whirlpool in the liquid. This raises the fill level at
the wall.

Testing temperature sensors

In order to guarantee excellent temperature
stability, the cycle time of the controller is set to
low and the control output is addressed on a
regular basis.

Control occurs via PID algorithm

6 Testing temperature

sensor

s

A separate temperature measuring instrument connected to the test specimen is required to test
the temperature sensors. By comparing the temperature displayed at the external measuring
instrument with the reference temperature it is possible to assess the status of the test specimen.
Remember that the test specimen requires a short period of time until it absorbs the temperature
of the metal block or liquid bath.

The internal references are set to normal when operating the multifunction calibrator, the micro­bath, the dry block and the infrared function; the selector switch should be turned to int. Ref.

CAUTION! Incorrect results!
It is not possible to calibrate earthed thermal elements, because the heating block is earthed

and any measurement would produce incorrect results.

It is possible to carry out a gradient control yourself and thus determine the time in which the set
temperature is reached. The time can be shorter or longer than the time usually required by the
calibrator / micro calibration bath.

y

When modifying the set temperature or switching on the calibrator / micro calibration bath it is
automatically determined which of the gradients (heating gradient “SLor” or cooling gradient
“SLoF”) is to be used.

Additionally, you can ensure that the calibrator / micro calibration bath switches to the set
temperature in set point memory SP2 as soon as the set temperature in set point memory SP1
has been achieved and after a programmed duration time “dur.t”; this creates a simple
temperature profile.

After switching on the calibrator / micro calibration bath the temperature profile is

Cooling gradient „SLoF“:

The cooling gradient "SLor" is active if the reference temperature is higher than the set
temperature. Only settings below the cooling capacity of the calibrator have an effect on the

Duration time „dur.t“:
The duration time "dur.t" is active if the set temperature SP1 has been achieved. Subsequently, the
calibrator / micro calibration bath automatically switches to set temperature SP2.

ACTIVATE TEMPERATURE PROFILE!
If you have carried out settings for these three settings, the calibrator / micro calibration bath
uses the new values only when modifying the set temperature or switching the calibrator off
and on again.
A further procedure is to switch off the automatic control prior to modifying parameters and
to switch it on again afterwards (� § 7.3.1).

CAUTION! Risk of burns:
Prior to transport or contact with the metal block / liquid bath ensure that it has cooled down

sufficiently; otherwise there is a risk of severe burns at the metal block / liquid bath and the
test specimen.



In order to cool down the metal block / liquid bath quickly, set the set temperature to a low

temperature, e.g. room temperature.

The installed fan gently and automatically switches to a higher speed for heating instruments,
thus providing more cooling air. The LED OUT 2 indicates the status of the output for the fan
control. If the LED OUT 2 lights up, the fan is running at high speed. If the LED OUT 2 does not light
up, the fan is running at low speed.

The controller switches the active cooling on for heating / cooling instruments. The LED OUT 2
indicates the status of the output for the active cooling. If the LED OUT 2 lights up, the active
cooling is running. If the LED OUT 2 does not light up, the cooling is not active.

PLEASE NOTE:
After switching off or after removing the mains connection, the installed fan can no longer
provide cooling air. Nevertheless, sufficient thermal isolation between the metal block / liquid
bath and the housing is still guaranteed.

9.2 Cleaning

External cl

eaning:

Clean the DryTC / LiquidTC with a dry or slightly damp lint-free cloth. Do not use sharp objects or
aggressive agents for cleaning.

Cleaning the fan grille:
Each calibrator is fitted with a small meshed air grille via which cooling air enters the calibrator.

 Clean the grille at regular intervals (vacuuming or brushing) depending on the level of air

pollution.

Cleaning calibrators with sleeves:
A small amount of brass dust is created when operating calibrators with sleeves, this can cause
the metal block and sleeve to jam.

 To prevent this, remove the sleeves from the heating block at regular intervals and if the

calibrator is not going to be operated for a longer period.

 Flush the heating block bore with compressed air and clean the bore and sleeve with a

dry

cloth.

CAUTION! Dangers of compress air and brass dust
Please aware about the dangers of using compress air and the danger created by the
expelled brass dust.



Always necessary to use a suitable breathing mask, gloves, safety glasses and clothing.

Cleaning the micro calibration bath:
Silicone oil:

 Drain as much of the silicone oil as possible with the aid of the supplied bilge pump.
 Subsequently remove the sensor cage from the tank and clean the cage, magnetic stirrer and

the tank with water and plenty of washing-up liquid. Allow everything to dry

completely.

Distilled water:

 If you are using distilled water, remove the calibration liquid and allow the sensor cage,

magnetic stirrer and tank to dry

completely.
