The TH1951 is a high speed、high accuracy , 120,000 counts meter that meets the measurement needs of voltage、current and resistor. Its outstanding performances, such as high Reading Rate ( Max . 40 Readings/ Second ) ,and DC Voltage measurement accuracy up to 0.01%, provides an ideal cost-effective option for customer. The concise design of front panel of TH1951 makes it easier to locate and select the measurement function. High brightness vacuum fluorescent display allows the user to view clearly. Its 12 different measurement capabilities, including DCV/ACV、DCI/ACI、Ω2W/Ω4W、Frequency/period、Diode Test /Continuity、dB/dBm, cover all basic measurement needs. Many new technologies have been adopted in TH1951, such as high speed low noise 26 bits A/D converter which gives the good linear and low noise performances. Fast response servo amplifier, floating power source and low offset buffer amplifier constitute front end of servo so as to remove the traditional attenuation、reduce offset drifting as well as to increase measurement rate. The SMD in the meter reduces the system density and volume. TH1951 adopts special input over load protect circuit which can stand 1500V voltage between input and ground. When over loaded, it can reset fast so as to ensure the safety and reliability of the equipment. Standard GPIB and RS-232 Interface with universal communication software is used in TH1951 for easy communication, data analysis and statistics as well as construction of automatic measurement system. The system accepts SCPI ( standard commands for programmable instrument ), it is compatible in communication software.
