UT131 Palm Size Multimeter
Input impedance: about 10MΩ ,
Results might be unstable at mV range when no load is connected. The value becomes stable
once the load is connected. Least significant digit ≤±3
Max input voltage: ±250V, when the voltage≥ 610V, "OL " symbol appears.
Overload protection: 250Vrms(AC/DC)
