*
Do not operate the measuring device unsupervised or only
protected against unauthorized access.
*
Use the device only for the purpose of its determination and pay
particular attention to warning notices on the device and
information on the maximum input values.
Electric safety:
*
Voltages over 25 VAC or 60 VDC are generally considered
dangerous voltages.
*
Only work on dangerous voltages by or under the supervision
of qualified personnel.
*
When working on dangerous voltages, wear suitable protective
equipment and observe the relevant safety rules.
*
Do not exceed the maximum permissible input values under any
circumstances (risk of serious injury and / or destruction of the
device)
*
Pay special attention to the correct connection of the test leads
*
Remove the test probes from the measurement object before
changing the measuring function.
*
Do not clamp around conductors with voltages equal or
exceeding 1000 V DC or 750 V ACrms (P 4300) 300 V DC or
240 V ACrms (P 4250)
*
Do not use these instruments for high-energy industrial
installation measurement. These instruments are intended for
use in installation overvoltage category II
*
Check test leads and probes for faulty insulation or bare wires
before connection to the equipments.
Measurement environment:
*
Avoid any proximity to explosive and flammable substances,
gases and dust. An electric spark could lead to an explosion or
deflagration - danger to life!
*
