I. I. I. Summary Summary
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.

1. 1. 1. Safety Safety notice Safety notice 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;
1-6. Introduction for safety sign
" " Dangerous voltage existing; "
isolation; " " Shall refer to the user's manual; " " Low battery.
