Instruction Manual Model 193A System DMM 01985, Keithley Instruments, Inc. Instrument Division Cleveland, Ohio, U.S.A. Document Number 193A-901-01 SAFETY PRECAUTIONS The following safety precautions should be observed before operating the Model ~193A This instrument is intended for use by qualified personnel who recognize shock huxds .~nd are i,lmiliar with the safety precautions required to avoid possible injury. Read WET the manual carefully before operating this instrument. Exercise extreme caution when a shock hazard is present at the instrument's input. The American National Standards Institute (ANSI) states that a shock hazards exists when voltage levels greater than 3OV rms or 42.4V peak are present. A good safety practice is to expect that a hazardous voltage is present in any unknown circuit before measuring. Ins ect the test leads for possible wear, cracks or breaks before each use. If any defects are found, replxe wt .R 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, before 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 lest or power line (earth) ground. Always make measurements with dry hands while standing on `1 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, etc). Refer to the t ligh 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.
