Chapter 1 Meter Safety Standards This style of digital multimeter is designed and manufactured according to the safety requirements set out by the IEC61010-1 standards for electronic test instruments and the hand-hold digital multimeters. Its design and manufacture is strictly based on the provisions in the 1000V CATIII of IEC6060-1 and the Stipulation of 2-Pollution Grade.
Chapter 2 Characteristics • 500 counts measurement • ACV and DCV measurements reach up to 1000V • DC measurement accuracy reaches up to 0,1% • 0,1 Ω resistance resolution and 10µ V voltage resolution • Linear frequency measurement logic frequency/duty ratio measurement •...

AVG MAX MIN Indicating the display value being the current value(MAX MIN),the maximum value(MAX),the minimum value(MIN) and MAX MIN the average value(AVG) Indicating it is now in the data-holding state Warning symbol that the input signal is the high-voltage Indicating it is now in the AC measurement state Indicating it is now in the DC measurement state Indicating the measurement value being negative Indicating the overload in the insulation resistance...
AC voltage and AC current are true effective values, which distinguishing this meter from the meters which only can measure the AC average value. ● Automatic and manual ranges: When turning on the meter’s power switch the meter defaults the automatic range state (AUTO displaying), and simultaneously it will automatically select the proper range according to the measured electric parameters.
