▪In the event of malfunction, switch the meter off immediately. If smoke or odors occur for which the
meter is the cause, remove the battery from the meter –risk of fire and injury.
▪Do not use the meter in proximity to flammable or combustible gases, as there is a risk of fire and
explosion.
▪Keep the meter and all accessories out of the reach of children –risk of suffocation and strangulation
due to parts which can be swallowed, as well as carrying straps and cables.
▪Do not dismantle, modify or repair the meter –risk of injury, fire and electric shock.
▪Do not expose batteries to moisture, high heat or open fire, and never short circuit batteries or
attempt to open them. Use only batteries which are recommended for this meter and which
demonstrate no apparent damage. Improper handling of batteries can result in fire, explosion,
serious injury or environmental damage.
▪When measuring hazardous radiation, observe all applicable safety regulations and use the
stipulated protective equipment. Non-compliance may result in significant impairment of health.
Meter settings and stored measured values are retained when the battery is changed. If you wait too
long to change the battery, it may become necessary to reset date and time.
Warning!

▪Remove the batteries from the meter if it’s not used for lengthy periods of time, or when they’re
fully depleted. In particular in the case of depleted batteries, leakage may occur and the meter
may be damaged.
▪Ensure correct polarity when inserting the battery.
▪When plugging in the measuring probe, make sure that the plug and socket guides are correctly
aligned and avoid the use of excessive force. An incorrectly connected probe can damage the
meter or the probe.
▪Do not use the meter where it is exposed to moisture or rain, and do not immerse it in water. Avoid
operation with wet or damp hands as well. This may result in electric shock or damage to the
meter.
▪Do not dismantle, modify or repair the meter. This may result in erroneous measurement results
