Never point the laser beam directly or indirectly (on reflective surfaces) towards the eyes. Laser radiation can cause irreparable damage to the eyes. You must first deactivate the laser beam when measuring close to people.

General safety notes

| WARNING
Unauthorized changes or modifications of the instrument are forbidden – such changes put the approval (CE) and safety of the instrument at risk. In order to operate the instrument safely, you must always observe the safety instructions, warnings and the information in the “Proper and Intended Use” Chapter
---|---
| WARNING
Please observe the following information before using the instrument:
Do not operate the instrument in the proximity of electrical welders, induction heaters and other electromagnetic fields.
After an abrupt temperature fluctuation, the instrument should be allowed to adjust to the new temperature for about 30 minutes before using it. This helps to stabilize the IR sensor.
Do not expose the instrument to high temperatures for a long period of  time.
Avoid dusty and humid surroundings.
Measurement instruments and their accessories are not toys. Children should never be allowed access to them!
In industrial institutions, you must follow the accident prevention regulations for electrical facilities and equipment, as established by your employer’s liability insurance organization.

Please observe the following five safety rules:

1. Disconnect.
2. Ensure that the instrument cannot be turned back on again.
3. Ensure isolation from the main supply voltage (check that there is no voltage on both poles).
4. Earth and short-circuit.
5. Cover neighboring parts that are under live electrical load.

Safety precautions

The TB 313 left the factory in proper and safe working order. In order to maintain this condition, the user must observe the safety notes contained in this manual.

| CAUTION!
Use only the enclosed safety measurement leads or equivalent measurement leads that meet the correct measuring category CAT III 600 V.
---|---

In order to avoid an electrical shock hazard you must observe the specified precautionary measures when working with voltages greater than 120 V (60 V) DC or 50 V (25 V) eff AC. These values represent the specified limits of safe-to- touch voltages in accordance with DIN VDE (values given in brackets apply to medical or agricultural applications).
Before taking each measurement, ensure that the test leads and the measuring instrument are in a flawless condition.
The test leads and test probes must only be handled using the isolated grips. Avoid touching the tips of the test probes under all circumstances.

The test instrument must only be used for the specified measurement range.

According to the standard EN 61010-1 the following measurement categories are defined:

Measurement Category CAT II
Measurements on circuits that are electrically connected directly to the network, via plugs in the home, office and laboratory. Measurement Category CAT III

Measurements on the building installations:
Fixed consumer units, distributor connection, equipment fitted permanently to the distributor.

Measurement Category CAT IV
Measurements at the source of the low voltage installation: Meter, primary surge protection, main connection.
