OVERVIEW
The VC88E digital multimeter is a battery-driven 3-
¾"
digital multimeter. It uses an LCD with a 23 mm-
high display for easy reading. The automatic overload protection feature makes operation more convenient.
The digital multimeter has the function of measuring DCV, ACV, DCA, ACA, resistance, capacitance,
frequency, temperature, both Fahrenheit and Celsius, duty cycle and diode and a continuity performance
test. The meter provides an analog bar and unit symbol display, data holding function (HOLD), relative
value measuring (REL), maximal/minimal value measuring (MAX/MIN), auto/manual range switching
(RANGE), auto power off and warning functions. It uses a double integral A/D converter as its core. It is
an ideal tool for labs, factories, radio-technology and field use.
SAFETY NOTES:
The instrument is designed according to IEC1010 standard (safety standard issued by International
Electro Technical Committee). Please read the following before operation.
1. A voltage of less than 36V is a control and safety voltage. When measuring voltage higher than
36VDC or, 25VAC, check the connection and the insulation of the test leads and probes to avoid
electric shock.
2. Never apply voltage higher than 1000VDC or 750VAC when measuring.
3. Be careful when measuring a voltage higher than 60VDC or 40VAC.
4. Select the correct function and range to avoid faulty operation.
5. Move the test leads away from test points when switching functions.
6. Never input voltage when measuring current.
7. Never modify the meter’s internal circuits.
8. Code for safety symbols:
= high voltage present;
= GND;
= dual insulation;
= refer to manual;
= Low battery
