Model 6517B Electrometer Reference Manual Section 14: SCPI command reference6517B-901-01 Rev. C / August 2015 14-65:LLIMit This command is used to set the lower limit for volts and amps.Usage[:SENSe[1]]:VOLTage[:DC]:RANGe:AUTO:LLIMit [:SENSe[1]]:CURRent[:DC]:RANGe:AUTO:LLIMit :ULIMit?DEFaultMINimumMAXimum:LLIMit?DEFault:LLIMit?MINimum:LLIMit?MAXimum Query largest allowable lower limit 0 to 210: Range limit for volts 0 to 21e-3: Range limit for amps DEFault : 210 (volts) 21e-3 (amps) MINimum: 0 (volts and amps) MAXimum: Same as DEFaultDetailsAutomatic range changes slow down the reading rate. By setting upper and lower measurementrange limits, you can prevent inadvertent range changes to ranges that you are not going to use.The upper range limit is selected by specifying the maximum expected reading that you expect tomeasure. For example, if the maximum expected reading is approximately 1mA, let the parameter() = 0.001 (or 1e-3). The lowest (most sensitive) range that can measure 1 mA is the 2 mA range.Thus, the 2 mA range is selected as the upper range limit. With this upper limit, the instrument cannotuprange to the 20 mA measurement range.The lower range limit is selected by specifying the lowest expected reading that you expect tomeasure.Also see:LGRoup (on page 14-66)
