Victor VC9801A Operation Manual

DIGITAL MULTIMETER

OPERATION MANUAL
1. GENERAL
The instrument is a stable and high performance digital multimeter driven by
battery. It uses the LCD with 42mm high make the reading is clearly. And the
function of 20sec. back light and overload protection make operation is
convenient.
The instrument has the function of measuring DCV, ACV, DCA, ACA,
resistance, capacitance, and diode, triode and continuity test. The instrument
takes dual-integral A/D converter as key point, is an excellent tools.
2. SAFETY NOTES
This series meter meets the standard of IEC1010. Read it before operation.
1 ． Do not input the limited voltage of 1000V DC or 750V AC RMS when
measuring voltage.
2．Voltage less than 36V is safety voltage. When measuring voltage higher than
36V DC, 25V AC, check the connection, insulation of test leads to avoid
electric shock.
3 ． When changing function and range, test leads should be removed from
testing point.
4．Select correct function and range.
5．When measuring current, do not input current over 20A.
6．Safety symbols
" " exists high voltage，"
" must refer to manual，"
