to follow these safety instructions could result in personal injuries or risk of
fire.
● Use proper power cord. Please use power cord specified for this product and
certified for your country/district of use.
● Connect and disconnect properly. Do not connect or disconnect probe or test
leads while they are connected to voltage source. Disconnect the probe
input and the probe reference lead from the circuit under test before
disconnecting the probe from the measurement instrument.
● Observe all the terminal ratings. To avoid fire or shock hazard, please do not
measure signals at DC40V or above. Consult the product manual for further
ratings information before making connections to the device.
● Do not operate in wet/damp conditions.
● Do not operate in a potentially inflammable/explosive atmosphere.
● Please keep the surface of the product clean and dry.
