Safety
2.4 Intended use
• Please observe that the device is not designed for continuous operation. The useful life of
the device is limited by software and via temperature monitoring. As soon as the internal
operating temperature has reached the maximum value, the function of the device will be
restricted in order to allow the device to cool down.
• Disconnect the device from the PV generator immediately after finishing the test or
measurement.
• Use the 4 mm test sockets only in electric circuits up to overvoltage category CAT III with a
conductor for a maximum of 300 V to earth. Before measurements in electric circuits of
overvoltage category CAT III, attach the enclosed protective caps onto the contact tips.
• Do not touch any metal parts of the test object during tests and measurements.
• If you want to use the device to prove the presence of a dangerous voltage, test the device
before and after this measurement on a known voltage source or test equipment.
WARNING
Dangerous voltage
Danger to life or serious injury is possible due to contact with high electric voltage in case of
incorrect operation.
• Do not touch the bare measuring probe tips of the safety measuring lines or the bare
contacts of the optional alligator clips, Only touch the safety measuring lines in the area
intended for your hands.
• Please note that dangerous testing voltages might be present at the device during insulating
resistance measurement. These might also be applied to the measuring circuit if safety
measuring lines are contacted.
• Connect the safety measuring lines to the correspondingly marked measuring jacks of the
device and check them for tight fit.
• Only use approved safety measuring lines.
• Attach the protective caps to the contact tips of the safety measuring lines (circuits of
overvoltage category CAT III or IV).
• When disconnecting the measuring circuit, first remove the live safety measuring line
(phase) and then the neutral safety measuring line from the measuring point.
WARNING
Opening the device
Danger to life or serious injury is possible due to contact with high electric voltage when opening
the device. The device might get damaged.
• Make sure that the device is free of voltage before opening the battery compartment.
• Do not open the device (except for the battery compartment).
• Please contact your specialty retailer or the returns management for any repairs [} page 9].
