• Input impedance: 10MΩ.
• Overload protection: 000VDC or 750V alternating peak.
• Display: Mean value response (calibrated with sine wave).
• Frequency response: (40-400)Hz.
• Duty Cycle Display: (0.1%-99.9%).
DC Current (DCA)
. Press the “ mA “ button or “ A “ button.
Plug the black meter pen into the terminal of
“COM” and the red meter pen into the terminal
of “mA” or “0A”. See the picture below.
2. Circularly press the “ mA “ button or
“ A “ button. Select automatic DC 600mA
and 0A current to test. The “DC”,“AUTO”,
“APO” symbols will appear on the LCD screen.
3. In case “OL” is displayed on the display, it indicates the current being measured has
exceed the current range, and please select higher ranges for measurements.
Caution:
a) At the 0A mode, current bigger than 0A
cannot be measured, and at mA mode,
the current bigger than 600 mA cannot be
measured. Otherwise this will lead to the
burning of the fuse or damage the instrument.
b) When the meter pen is plugged in the
input terminal of the current, it is strictly
prohibited to have the meter pen connected
in parallel on any circuits.
