Remark
- * True RMS measuring reading for ACV and ACA function.
- * Input impedance for ACV & DCV range is 10 Meg ohm.
- * ACA, ACV frequency response is from 40 to 1 KHz.
- * ACA, ACV specification be tested on sine wave 50/60 Hz.
Diode
- Short/non conductance, good/defect test.
Continuity
- If measuring resistance is less than 10 ohm, the beeper will sound .
