Caution:
1. Don’t measure voltages over 750V; otherwise, the meter will be
damaged.
2. When measuring high voltage, special attention should be given to
personal safety and avoid your body getting in touch with high
voltage circuit.
Input Impedance: 10MΩ .
Overload Protection: 1000V DC or 750 AC peak value.
Frequency Response: (40~1000) Hz; True RMS display.
The value of the AC voltage measured with this meter is True RMS
(root mean square). These measurements are accurate for sine
wave and other waves (without DC offset), square wave, triangular
wave and step wave.
2-2-3. DCA
A) Insert the black test lead into the “COM” input terminal and red test
lead into the “mA “ input terminal. (Max 600mA), or “10A “input
terminal (Max 10A).
B) Rotate function switch to Current (uA/mA/A) setting. The initial state
of the meter is in auto range status, which shows “DC” symbol. Then
connect the test lead to the tested circuit in serial, the tested current
value and the current polarity of the point where the red pen is
contacted will be displayed on the screen simultaneously.
Caution:
1. If “OL” is displayed on LCD, it indicates the tested current value has
exceeded the present range limit, please select higher range to
complete the measurement.
2. The Max input value is 600mA or 10A. (Depending on the terminal
