be inserted in the device.
• Do not use the instrument while charging the battery pack
(Z502H).
• Do not use the test instrument if the battery compartment lid
has been removed.
Touch contact with dangerous voltage is otherwise possible.

Defective fuses must be replaced. See detailed operating
instructions.
Measurement Cables and Establishing Contact
• Plugging in the measurement cables must not necessitate any
undue force.
• Never touch conductive ends (e.g. of test probes).
• Fully unroll all measurement cables before starting a test/mea-
surement. Never perform a test/measurement with the mea-
surement cable rolled up.
• Avoid short circuits due to incorrectly connected measure-
ment cables.
• Ensure that alligator clips, test probes or Kelvin probes make
good contact.
Data Security
• Always create a backup copy of your measurement data.
• Observe and comply with the respectively applicable national
data protection regulations. Use the corresponding functions
provided by the test instrument such as access protection, as
well as other appropriate measures.
