Disconnect the test leads from the tested circuit before rotating the
range selector in order to change functions.
When carrying out measurements on a TV set or switching power
circuits, always remember that the meter may be damaged by any high
amplitude voltage pulses at test points.
Always be careful when working with voltages above 60 VDC or 30 VAC
rms. Keep your fingers behind the probe barriers at all times during
measurement.
Never perform resistance, diode or continuity measurements on live
circuits. Make sure all capacitors in the circuit are depleted.
Always hold the device behind the finger guard (see General
Description, nr. 12).
Comply with the local and national safety regulations. Use personal
protective equipment, such as approved rubber gloves, face protection
and flame-resistant clothing, to prevent shock and arc blast injury
where hazardous live conductors are exposed.
Do not use this device to measure a current with a frequency
above 1 kHz.
Only use this device as specified in this manual in order not to
compromise the protection supplied by the device.

7. Overvoltage/Installation Category
DMMs are categorized depending on the risk and severity of transient
overvoltage that might occur at the point of test. Transients are short-lived
bursts of energy induced in a system, e.g. caused by lightning strike on a
power line.
