Instruction Manual Model 193 System DMM 01985, Keithley Instruments, Inc. Instrument Division Cleveland, Ohio, U.S.A. Document Number 193-901-01 SAFETY PRECAUTIONS The following safety precautions should be observed before operating the Model `I93 This instrument is intended for use by qualified personnel who recognize shock hazards ,Ind arc f~u~~ili.~t with the safety precautions required to avoid possible injury. Read over the manual carefully bei~rc upcrating this instrumen(. Exercise extreme caution when a shock hazard is present at the instrument's input. The American Nati,,nal Standards Institute (ANSI) states that a shock hazards exists when voltage levels greater than XlV rms 01 42.4V peak are present. A good safety practice is to expect that a hazardous voltage is present in any unknown circuit before measuring. Inspect the test lends for possible wear, cracks or breaks before each use. If any defects are fl,und, wplxe with test leads that have the same measure of safety as those supplied with the instrument. For optimum safety do not touch the test leads or the instrument while power is applied to the circuit under test. Turn the power off and discharge all capacitors, bcforc connecting or disconnecting the instrunwnt. Always disconnect all unused test leads from the instrument. Do not touch any object which could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, ill- s&ted surface, capable of withstanding the voltage being measured. Exercise extreme safety when testing high energy power circuits (AC line or mains, ctc). Refer tu the fligh Energy Circuit Safety Precautions found in paragraph 2.6 (Basic Measurements). Do not exceed the instrument's maximum allowable input as defined in the specifications and operation section.
