All-Sun EM420B Digital Multimeter Diode Transistor Battery Tester AC/DC Ammeter Voltmeter Ohm Portable Meter Voltage Meter
1.It is compact 3 1/2 digits digital multimeter for measuring DC and AC voltage,
DC and AC current, resistance, temperature, diode, transistor, continuity, capacitance.
2. It has polarity indication, data hold, MAX mode, overrange indication and auto power off.
3. It is easy to operate and is a ideal instrument tool.
Measuring AC/DC current >>>
Connect the negative(-) output lead of the selected clamp to the "COM" jack,
Connect the positive(+) output lead of the clamp to the "INPUT" jack.
Clamp the circuit to be measured with the clamp.
Read the reading on the display.
