• The instrument and the accessories may only be used for the tests/measurements described
in the documentation for the instrument.
• Route cables in an orderly fashion, e.g. the power cable and cables of accessories. Loose,
disorderly cables result in unnecessary danger of tripping and falling.
• The integrated voltage measuring function and mains check may not be used to test systems
or system components for the absence of voltage.
Testing for the absence of voltage is only permissible with a suitable voltage tester or voltage
measuring system which fulfills the requirements specified in DIN EN 61243.
Operating Conditions
• Do not use the instrument and its accessories after long periods of storage under unfavorable
conditions (e.g. humidity, dust or extreme temperature).
• Do not use the instrument and its accessories after extraordinary stressing due to transport.
• The instrument must not be exposed to direct sunlight.
• Only use the instrument and its accessories within the limits of the specified technical data
and conditions (ambient conditions, IP protection code, measuring category etc.).
• Do not use the instrument in potentially explosive atmospheres.
Rechargeable or regular batteries
• Use batteries in undamaged condition only. Risk of explosion and fire in the case of damaged
batteries!
Inspect the batteries before use. Pay particular attention to leaky and damaged batteries.
• If you are using rechargeable or regular batteries, the instrument must only be used with
inserted and properly closed battery compartment lid. Otherwise, dangerous voltages may
occur at the contacts of the rechargeable or regular batteries.
Gossen Metrawatt GmbH
• Do not use the instrument while the internal batteries are being charged.
• Charge rechargeable batteries in undamaged condition only. Risk of explosion and fire in the
case of damaged rechargeable batteries!
Fuses
• The instrument may only be used as long as the fuses are in flawless condition. Defective
fuses must be replaced. Fuses may only be replaced by our repair service department.
• Never bridge the fuses. Never put the fuses out of operation.
Measurement Cables and Establishing Contact
• Plugging in the measurement cables must not necessitate any undue force.
• Never touch conductive ends (for example of test probes).
• Fully unroll all measurement cables before starting a test/measurement. Never perform a
test/measurement with the measurement cable rolled up.
• Avoid short circuits due to incorrectly connected measurement cables.
• Ensure that test probes, etc. make good contact.
• If possible, move or remove the connectors, test probes, alligator clips, or Kelvin probes only
when testing/measurement has been completed.
Unwanted sparking may otherwise occur due to test current.
Data Security
• Always create a backup copy of your measurement data.
• Observe and comply with the applicable national data protection regulations. Use the corre-
sponding functions provided by the instrument such as access protection, as well as other
appropriate measures.
