AIDETEK VC99+ User Manual

User's manual for VC99+ 3 6/7 DMM
1.SUMMARY
This AIDETEK VC99+ multimeter is a steady
performance, battery-driven 3 6/7 digital multimeter. It uses
the LCD with 23mm-high figure to make the reading clear
and make operation more convenient.
The digital multimeter has the function of measuring DCV,
ACV, DCA, ACA, resistance, capacitance, frequency,
temperature, duty cycle, transistor and diode, continuity
performance test .The meter can provide functions including
analog bar and unit symbol display, data holding, relative
value measuring, maximal/minimal
auto/manual range switching (RANGE), auto power off and
warning functions .it adopts double integral A/D converter as
its core. It is an ideal tool for labs, factories and
radio-technology.
2.SAFTY NOTES ： ： ： ：
The instrument is designed according to IEC1010
standard (safety standard issued by International Electro
technical Committee). Please read the following before
operation.
1-1.Check the connection and insulation of test leads to avoid
electric shock.
1-2.Do not input a limited voltage higher than DC 1000V or
AC 750V when measuring ranges.
1-3.When measuring voltage higher than DC 60V, AC 40V,
please be careful.
1-4. Select correct function and range to avoid fault operation.
1-5.Please move the test leads away from test points when
switching the function.
1-6.Please don't input voltage value when measuring current.
1-7.Please don't modify the circuit.
1-8.Introduction for safety symbol:
" " exists high voltage; "
" " must refer to manual "
