Keithley Digital Multimeter with Communication Interface RS 232

Keithley Model 2750 Digital Multimeter / Data Acquisition / Switch / Data Logging System GPIB Interfaceimportant features and advantages
1. Each channel can be fully configured - each channel can be independently configured for measurement. Parameters that can be selected for each channel, including speed, range, resolution, number of power line cycles (NPLC), filter type, offset compensation, mathematical functions to be displayed, CJC type, RTD type, frequency gate Frequency gate time, values of m and b in the mX+b format, H/LO limit, low ohm (type 2750 only), ratio calculation, and thermistor type.
2. Channel monitoring function - monitors any specific input channel on the front panel display during the scanning process. This function can also be used as an analog trigger to initiate a scan sequence based on some external factors, such as when the temperature rises above a preset limit. only the data of interest is received, so it is not necessary to spend hours searching for abnormal data in normal readings.Number of differential input channels270027102750Matrix intersection80 80200Dry circuit ohms (20mV clamp)96 96240Number of slots100uohm100uohm1 uohmMemory buffer readingNoNoYesSize (2U height)55,000 readings450,000 readings110,000 readingsCommunication InterfaceHalf rack widthHalf rack widthFull rack width (19)Scan rate (memory)GPIB, RS-232Ethernet,RS-232GPIB,RS-232Scan rate (electronic channel)180/s500/s230/sMaximum internal trigger rate145/s440/s210/sMaximum external trigger rate2000/s 2800/s2000/sNumber of differential input channels375/s2000/s375/s
