Safety precautions

This product complies with the requirements of the following directives of the European Union for CE conformity: 2014/30/EU (electromagnetic compatibility).
We herewith confirm that this product meets the essential protection standards, which are given in the directions of the council for adaptation of the administrative regulations for the UK of Electromagnetic Compatibility Regulations 2016 and the Electrical Equipment (Safety) regulations 2016.

The following safety precautions must be observed before operation. Damages resulting from failure to observe these safety precautions are exempt from any legal claims:

• Comply with the warning labels and other info on the equipment.
• Do not subject the equipment to direct sunlight or extreme temperatures, humidity, or dampness.
• Do not subject the equipment to shocks or strong vibrations.
• Allow the equipment to stabilize at room temperature before taking up measurements (important for exact measurements).
• Replace the battery as soon as the battery indicator “BAT” appears. With a low battery, the meter might produce a false reading that can lead to electric shock and personal injury.
• Fetch out the battery when the meter will not be used for a long period.
• Periodically wipe the cabinet with a damp cloth and mild detergent.
• Do not use abrasives or solvents.
• Do not operate the meter before the cabinet has been closed and screwed safely as the terminal can carry voltage.
• Do not store the meter in a place of explosive, inflammable substances.
• Do not modify the meter in any way.
• Opening the equipment and service- and repair work must only be performed by qualified service personnel.

Cleaning the cabinet
Clean only with a damp, soft cloth and a commercially available mild householder cleanser. Ensure that no water gets inside the equipment to prevent possible shorts and damage to the equipment.

Performing Measurement

General:

1. Turn off the machine using the ON button (2).
2. Press the “FAST / SLOW” button (3) to switch the desired term evaluation.
3. Press the “MAX / MIN” button (4) to switch to the maximum value mode. The meter is now renewed only if the current measured value exceeds the highest previous reading.
4. Press the “MAX / MIN” button (4) again to switch to the minimum value mode. The meter is now renewed only if the current measured value is less than the lowest previous reading
5. Press button (4) again to switch back to the normal measurement mode.

Automatic Power Off
If the device is not used, it automatically turns off after 10 minutes.
For continuous measurements, the automatic shutdown can be disabled:

1. Turn off the unit (if necessary) with the ON button (2)
