CAUTION
• Disconnect the test leads from the test points before changing the position of
the function rotary switch
• Never connect a source of voltage with the function rotary switch in the Ω,
50V,100V,250V, 500V or 1000V position
• Do not expose the instrument to extremes in temperature or high humidity
• Never set the instrument in Ω, 50V,100V, 250V, 500V or1000V function to
measure the voltage of a circuit. This could result in damage to the tester and
the equipment under test.
