Its outstanding performance,such as max.1,200,000 counts, high reading rate1000 meas/sec as well as DC voltage accuracy of 0.0035% provides an ideal costeffective option for customer.The concise design of front panel of TH1951/TH1961 makes it easier to locate and select the measurement function. High brightness VFD display allows the user to view clearly. Its 12 different measurement functions, including DCV/ACV, DCI/ACI, Ω 2W/Ω 4W, Frequency/Period, Diode Test, Continuity, dB/dBm, cover all basic measurement needs.Many new technologies have been adopted in TH1951/TH1961, 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 multimeter reduces the system density and volume.TH1951/TH1961 adopts special input overload protect circuit which can stand 1500V voltage between input and ground. When overloaded, it can recover fast so as to ensure the safety and reliability of the equipment.Standard GPIB, USB(or RS-232) interface with universal communication software is used with TH1951/TH1961 for easy TH1951/TH1961 communication, data analysis and statistics as well as construction of an automatic measurement system. The system accepts SCPI(standard commands for programmable instrument) command sets.
