Batteries

1Safety and disposal

•Improper use of batteries may cause destruction of the batteries, injuries due
to current surges, fire or the escape of chemicals.
•Only use the battery supplied in accordance with the instructions in the
instruction manual.
•Do not charge batteries. Attempting to charge a non-rechargeable battery
may cause gas to be produced or heat to be generated. That may lead to
the escape of gases, an explosion and/or possibly to fire.
•Do not short batteries. If the positive (+) and negative (-) terminals of a
battery are directly connected to one another, the battery will be shorted. For
example, batteries can be shorted when you have them loose in your pocket
along with keys or coins. This may lead to the escape of gases and the
leakage of battery acid.
•Do not deform batteries. Batteries must not be squashed, drilled, dismantled,
pierced, modified or damaged in any other way. This may lead to the
leakage of battery acid, to the escape of gases and/or to an explosion.
•Do not heat batteries above the permitted temperature or burn them. If a
battery is heated, this may lead to the leakage of battery acid and/or to an
explosion. Lithium batteries can, for instance, react very strongly in
combination with fire. This may involve battery components being emitted
with considerable power.
•Do not consume battery, risk of burns due to hazardous substances. Keep
new and used batteries away from children.
•In principle, contact with escaping battery components may present a risk to
health and to the environment. Adequate body and breathing protection is
therefore required when in contact with batteries that have peculiar aspects
(escaping contents, deformations, discolourations, dents or the like).
•Do not leave batteries lying around loose once they have been unpacked. If
batteries that have been unpacked are left lying around loose, they can
easily short one another, particularly button cells. In some cases, this is very
dangerous because the batteries may heat up. This may lead to an
explosion.
•Always store batteries in a cool, dry place.
•Batteries must be disposed of in accordance with the local and country-
specific regulations. In order to prevent short circuits and the associated
heating, lithium batteries must never be stored unprotected in bulk.
Appropriate measures against short circuits are for instance inserting the
batteries into the original packaging or a plastic bag, masking the poles or
embedding them in dry sand.
•Lithium batteries must be transported and shipped in accordance with the
local and country-specific regulations.
•Do not expose the batteries to heavy impacts, water or fire.
•Only use the batteries in environments with a maximum temperature of
+140 °C.

•Do not store unused batteries in the proximity of metal objects.
•Do not use any damaged batteries.
First-aid measures
•If there is any contact with the skin or eyes, the areas must be rinsed with
water for at least 15 minutes. If there is any contact with the eyes, a doctor
must be contacted in addition to the rinsing.
•If burns are caused, these must be treated appropriately. You are also
strongly advised to contact a doctor.
•Airways: Leave the room immediately when smoke development or gas
release is acute. Consult a doctor when amounts are larger and airways are
irritated.
•Swallowing: Rinse out mouth and surrounding area with water. Get medical
assistance immediately.
•In the event of contact with battery acid: rinse the affected areas thoroughly
with water and if necessary consult a doctor.

2.1 Use
Testo guarantees the functionality of its products when used in
accordance with their intended purpose. This guarantee does not apply
to features of Testo products in combination with unauthorized third-
party products. Competitor products are not authorized by Testo.
As is common practice, Testo generally excludes support, warranty or
guarantee claims relating to functionality that has not been guaranteed
by Testo as part of the product offered. Claims of this kind shall also be
excluded in the event of improper use or handling of the products, e.g.
in combination with unauthorized third-party products.
The testo 190 data loggers are used to measure individual temperature and
pressure readings and measurement series.
The testo 190 data loggers measure and store temperature and pressure
readings which, with the aid of the programming and readout unit and a USB
cable, are transmitted to the PC, where they can be read out and evaluated
using the testo 190 CFR software. The software enables the data loggers to be
individually programmed and the readings analyzed and printed out via a report
and subsequently archived.
Application examples
The testo 190-T1, testo 190-T2, testo 190-T3, testo 190-T4 and testo 190-P1
data loggers are ideal for measuring temperature and pressure in order to
validate sterilization processes in autoclaves, containers and freeze-drying
systems.
In conjunction with the freeze-drying probe holder, the testo 190-T3 and
testo 190-T4 data loggers are also ideal for measuring the plate surface
temperature distribution in freeze-drying systems.
All testo 190 data loggers can also be used for various control measurements of
temperature and pressure within the defined temperature range.

4 Operation
4.1 Bending flexible probe shafts
The testo 190-T3 and testo 190-T4 data loggers have flexible probe
shafts. The testo 190-T1 and testo 190-T2 data loggers are equipped
with rigid probe shafts, which must not be bent.
ATTENTION
Incorrect bending of the probe shafts!
Material fatigue and probe breakage!
-Begin bending the probe shafts only from a distance of 30 mm from the
housing material and 50 mm from the probe tip. Otherwise, the
mechanical stress caused by the housing and probe tip edge would be
too great.
-Do not use a clamp or any other tools to bend the probe shafts.
-The probe shaft of the data logger must not fall below the bending radius
of 50 mm. Small bending radii or rapid bending back and forth result in
material fatigue and premature probe breakage.
