This instrument is a highly sensitive \"FET electronic tester\" having the DC voltage function of which the internal resitance is as high as 2.5?12M?, and also the DC current function with the 0.12?A range.
Can also measure P-P value(the value between positive and negative peak values on sine wave alternating current) and very small electric current.
The frequency characteristic of AC low voltage ranges(3V and 12V) is 40Hz?1MHz(sine wave AC)
The Vp-p of triangular-wave, square-wave over 20% duty cycle voltages of waveforms can also be measured(at 3V range)
Zero center meter(NULL) of DC Voltage and DC Current
