TECPEL DMM-8007A Operation Manual

DIGITAL MULTIMETER
OPERATION MANUAL
1. GENERAL
The instrument is a stable and good performance digital multimeter driven by battery.
It uses the LCD with 42mm-high figure to make the reading clear. Unit symbol
displaying, backlight and the function of 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 700V 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 point 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， " " dual insulation， "
" " low battery
