MAXimum The measure function:• Current: CURRent[:DC]• Resistance: RESistance• Voltage: VOLTage[:DC] The number of power-line cycles for each measurement: 0.01 to 10DetailsThis command sets the amount of time that the input signal is measured.The amount of time is specified as the number of power line cycles (NPLCs). Each PLC for 60 Hz is16.67 ms (1/60) and each PLC for 50 Hz is 20 ms (1/50). For 60 Hz, if you set the NPLC to 0.1, themeasure time is 1.667 ms.This command is set for the measurement of specific functions (current, resistance, or voltage).The shortest amount of time results in the fastest reading rate, but increases the reading noise anddecreases the number of usable digits.The longest amount of time provides the lowest reading noise and more usable digits, but has theslowest reading rate.Settings between the fastest and slowest number of PLCs are a compromise between speed andnoise.If you change the PLCs, you may want to adjust the displayed digits to reflect the change in usabledigits.If you send this command without the parameter, it sets the NPLCs for all functions.
