Victor VC9808+ Operation Manual

DIGITAL MULTIMETER VC9808+
OPERATION MANUAL
1. GENERAL
The instrument is a stable and good performance digital multi-meter driven by
battery. It uses the LCD with 26mm-high figure to make the reading clear. Unit
symbol displaying, and the function of backlight and overload protection make
operation is convenient.
The instrument has the function of measuring DCV, ACV, DCA, ACA, resistance,
capacitance, inductance, temperature and frequency, and diode, triode and
continuity test. The instrument takes dual-integral A/D converter as key point,
is an excellent tool.
2. SAFETY NOTES
This series meter meets the standard of IEC1010. Please read below notes
carefully before operation.
1．Do not input a limited voltage which RMS is over DC 1000V or AC 750V when
measuring voltage.
2．Voltage less than 36V is a safety voltage. When measuring voltage higher
than DC 36V, AC 25V, check the connection and insulation of test leads to avoid
electric shock.
3．Be sure to keep the test leads off the testing points when converting function
and range
4．Select correct function and range to avoid fault operation.
5．When measuring current, do not input current over 20A.
6．Safety symbols
" " exists high voltage， " "GND， "
" " must refer to manual， " "low battery indication.
