1 Safety and disposal • Use only original spare parts from Testo. • External circuits may only be supplied with output voltages below the limits of 30 V RMS and 42.4 V peak or 60 V DC by a certified mains unit with reinforced or double insulation for protection against electric shock.
1 Safety and disposal • 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.

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.
Section 6, Technical data. 2.4 Power supply Large and small battery types are available for all testo 191 data loggers. For information on installing and changing the batteries, please refer to Section 3.1 Installing the battery and 4.2 Changing the battery. Section 6 contains the Technical data for the batteries.
2.6 testo 191 Professional software The testo 191 Professional software can be used to program the testo 191 data loggers via the programming and readout unit (e.g. measuring cycle, measurement start, measurement stop, etc.) and read them. It also offers calculation and analysis options for the measurement data acquired.
3 Commissioning 3 Commissioning 3.1.1 Installing the battery The testo 191 data loggers are supplied with a large battery as standard. The data logger can therefore be used in the temperature range from -50 °C to +140 °C. The small battery, which can be used in the temperature range from - 20 °C to +140 °C, can be purchased as an accessory.

3 Commissioning Tighten battery by turning clockwise. Avoid the use of force! Hand- tighten the battery. The marker on the battery must be located inside the position marking. The O-ring between the metal housing and the battery must no longer be visible.
The data loggers are supplied with the appropriate distance adapters. The testo 191-P1 data logger does not have a distance adapter and can be placed in the programming and readout unit without using one. Insert the distance adapter into the socket first.
Page 16
3 Commissioning Battery is connected Insert appropriate distance adapter into the socket. Insert data logger onto sliding bracket. Push the data logger in the direction of the arrow and click it into place in the distance adapter. The data logger is properly inserted if the isolator ring is between the two communication contacts.
PC via USB Please ensure that the case is securely positioned so that the case lid cannot fall onto the cable. The computer is started up and the testo 191 Professional software is enabled. The battery is connected to the data logger and is functional.
4 Operation 4 Operation 4.1 Bending flexible probe shafts The testo 191-T3 and testo 191-T4 data loggers have flexible probe shafts. The testo 191-T1 and testo 191-T2 data loggers are equipped with rigid probe shafts, which must not be bent.
4.2 Winding up probe shafts using a winding The use of a winding aid makes it easier to correctly wind up the flexible probe shafts of the testo 191-T3 and testo 191-T4 data loggers and enables compact and material-friendly storage.
4.3 Fitting a kink protector To prevent unauthorized/unintentional bending and winding of the flexible probe shafts of the testo 191-T3 and testo 191-T4 data loggers at the welding point, a kink protector can be retrofitted. The kink protector consists of a plastic clip and a stainless steel kink protector.
4 Operation ATTENTION Contaminated bend protection must be dismantled (follow the bend protection assembly in reverse order), cleaned and reassembled. 4.4 Changing the battery Before use, check that the battery is suitable for the operating temperature range. For the operating temperature range of the battery types, please read Section 6 Technical data.
Stored data is retained when the battery is replaced or if the battery fails. Connect new battery, see Section 3.1, Installing the battery. The battery replacement must be confirmed in the testo 191 Professional software. This can be done under the menu item Programming of loggers.
4.6 Aligning the can stand The can stand enables the testo 191-T1 data logger to be positioned in cans in a way that is stable and safe. Depending on the size of the can, the can stand can be bent into the correct position.
191-T1 data logger more stable. 4.7 Installing the can and bottle attachment Used in conjunction with the testo 191-T2 data logger, the can and bottle attachment enables the core temperature of food in cans and bottles to be measured during a pasteurisation process.
4.8 Changing the compression fitting When using the can and bottle bushing in conjunction with a testo 191-T3 and a testo 191-T4 data logger, the compression fitting must be changed due to the flexible probe.
Page 26
4 Operation Installation of the can and bottle attachment for the testo 191-T3 and 191-T4 data loggers on cans or bottles is carried out in the same way as steps 1 to 3 in the previous section. 1 Gripping section A...
4.9 Mounting the retaining clamp The testo 191-T1, testo 191-T2 and testo 191-T3 data loggers have a thread on the probe shaft, which is intended for attaching the retaining clamp. The data logger can therefore be attached in systems or loading baskets without the use of adhesive tape.
Page 28
4 Operation A fixing material (cable tie, wire, etc.) can be fed through the opening of the retaining clamp. Secure the data logger to an object (e.g. metal grid). No additional tools are required to attach the retaining clamp. Materials such as cable ties or wires are not included in the delivery.
Temperature data loggers: The testo 191 T1, testo 191 T2, testo 191 T3 and testo 191 T4 instruments must be completely immersed in a liquid bath during calibration, i.e. the probe, body and battery.
