2.0 Safety Measures
The respective accident prevention regulations established by the professio-
nal associations for electrical systems and equipment must be strictly met at
all times.
Measurements in dangerous proximity of electrical installations are only to
be executed when instructed by a responsible electrical specialist, and never
alone.
If the operator's safety is no longer ensured, the instrument is to be put out of
service and protected against use. The safety is no longer insured, if the in-
strument:
- shows obvious damage
- does not carry out the desired measurements
- has been stored for too long under unfavourable conditions
- has been subjected to mechanical stress during transport.
The instrument may only be used within the operating ranges as specified
in the technical data section.
Avoid any heating up of the instrument by direct sunlight to ensure perfect
functioning and long instrument life.
Never try to disassemble battery cells !The battery contains highly alkaline
electrolyte. Danger of causticization ! If electrolyte gets in contact with skin
or clothing, rinse immediately with water. If electrolyte gets in contact with
the eyes, immediately flush by using pure water and consult a doctor.
Never try to make contact between both battery cell poles, for example by
using a wire connection. The resulting short-circuit current is very high and
causes extreme heat. Danger of fire and explosion !
Never throw battery cells into a fire as this could cause an explosion.
Never expose batteries or accumulators to humidity.
When replacing or changing the battery, make certain of correct polarity.
At swallowing up of coin cells (for.ex., infants) consult a doctor.
Only use batteries as described in the technical data section.
2.1 Appropriate Usage
The instrument may only be used under those conditions and for those purposes
for which it was conceived. For this reason, in particular the safety references , the
technical data including environmental conditions and the usage in dry environ-
ments must be followed. When modifying or changing the instrument, the opera-
tional safety is no longer ensured.
3.0 Transport and Storage
Please keep the original packaging for later transport, e.g. for calibration. Any trans-
port damage due to faulty packaging will be excluded from warranty claims. Ho-
wever, should the instrument be contaminated by leaking battery cells, you are
kindly requested to return it to the factory for cleaning and inspection.Instruments
must be stored in dry and closed areas. In the case of an instrument being trans-
ported in extreme temperatures, a recovery time of minimum 2 hours is required
prior to instrument operation.
4.0 Carrying out measurement
Prior to any temperature measurement it has to be ensured, that the surface
to be measured is not live. Failure to comply with this prescription can lead
to serious operator injury or instrument damage.
Imperatively respect specified thermocouple measurement ranges.
The thermocouples may only be touched at handles provided. Any contact
with metal parts has to be imperatively avoided.
In order to avoid burns, the UUT may only be touched via measurement
probe.
In order to obtain the most accurate results the following points must be observed:
• For measurement of liquid, paste or solid material, the insertion depth of the sen-
sor must be approx. 30 mm.
• For measurement of surface temperatures, there must be reasonable heat con-
tact between the sensor and the object to be measured, i.e. the surface of both
the sensor and the object must be clean and the sensor must be placed verti-
cally on to the surface of the object. The use of thermal conductivity paste is sug-
gested.
✔ Switch on instrument wiht key ON/OFF
✔ Bring the object to be measured into contact with the temperature sensor.
The HOLD-function has to be switched „off".
✔ Wait until a steady value is displayed. Please note that the time required to ob-
tain the actual measurement value depends upon each individual application
(up to 30 seconds).
Over- and underload is displayed as "OL" or. "-OL" .
✔ The value displayed can be stored by use of the „HOLD" button. The display
shows „H".
5.0 Maintenance
When using the instrument in compliance with the instruction manual, no special
maintenance is required. Should operational problems occur during daily use, our
consulting service will be at your disposal, free of charge.
5.1 Cleaning
If the instrument is dirty after daily usage, it is advised to clean it by using a humid
cloth and a mild household detergent
Prior to cleaning, ensure that instrument is switched off
Never use acid detergents or dissolvants for cleaning.
After cleaning do not use the instrument until it is dryed completely.
5.2 Replacement of batteries
If you can´t switch on the instrument or if the display (segmets) is low after switch
on the insrument the batteries must be changed
The references described in section 2 regarding the handling of batteries
must be met! Only use batteries as described in the technical data section!
✔ Lift the upper case cover.
✔ Remove the discharged batteries.
✔ Insert new batteries.
✔ Replace the upper case cover.
Please consider your environment when you dispose of your one-way bat-
teries or accumulators. They belong in a rubbish dump for hazardous waste.
In most cases, the batteries can be returned to their point of sale.
Please, comply with the respective valid regulation regarding the return, re-
cycling and disposal of used batteries and accumulators.
