I. Summary
This series product is a stable and battery-driven 3 1/2 digital
multimeter with high reliability. It adopts LCD screen with character
height of 28mm; with functions including unit sign/backlight and overload
protection, it is easy to use.
This series of device can be used to measure DCV, ACV, DC, AC,
resistance, capacitance, inductance, diode, triode, open circuit,
temperature and frequency, as well as hold peak value. As an
instrument with excellent performance it adopts double integral A/D
converter as its core.
II. For purchasers of this multimeter
1. Safety notice
This series of device is designed according to IEC1010 standard
(safety standard issued by International Electrotechnical Committee).
Please read these safety notices before using it.
1-1. Never input DC higher than 1000V or AC higher than 750V virtual
voltage as measuring voltage;
1-2. The voltage lower than 36V is safe. Please confirm the earthing,
connection and isolation of pencils to avoid electric shock when
measuring the voltage of DC higher than 36V or AC higher than 25V;
1-3. Pencils should be away from test points when switching function or
range;
1-4. Select correct function and range and beware of miss-operation.
You may still be careful to ensure the safety even the device has range
protection functions.
1-5. Never input current higher than 20A when measuring current;
