Industrial True RMS Digital Multimeter Dmm for Capacitor Test
Initial acquaintance
The UT171 series of industrial-grade inspection-type digital multimeters can troubleshoot most industrial problems. UT171LOZ low impedance input, 3KΩ input impedance can effectively discharge the residual voltage and accurately determine whether the residual voltage exists.
This series of instruments also has 4-20mA loop, AC + DC, nS conductance, programmable square wave output, VFC frequency conversion and other measurement functions. It is a full-featured inspection instrument perfectly adapted to industrial applications, motor troubleshooting, and electrical engineering maintenance personnel.
Functional Features
59,999 digits, 0.025% basic DCV accuracy (Note: UT171A 39,999 digits)
AC voltage and current true RMS measurement
