ET111 Super Digital Multimeter Gerenal Description

Super Digital Multimeter ET111, a super digital multimeter with mirable innovative design and extremly high accuracy, expecially the timing function, which reaches 100 hours! Absolutely help alleviating fatigue when operating for long time continous measurement and totally save your time!

• 20000 count 4 1/2 digital analog triple display, accuracy of basic measuring range reached 0.05%
• With Panel calibration technology, more reliable since calibration factor setting inside and no need to adjust the potentiometer.
• TRMS measuring and the bandwidth of AC voltage reaches 20 kHz, it's very useful in non-sine signals detecting
• Frequency of detected signal display simultaneously with AC Voltage/Current measuring. Optionally display Duty cycle and Decibel value.
• TTL logic test, analog bar display high/low circuit balance.
• Data hold function and Max. /Min. record, 85 groups of data storage.
• Timing measuring function, Max 100 hours working and 100 groups of data auto-recording.
• Voltage/Current auto-measuring holding function, which facilitates online test.
• It's able for difference setting and difference sorting in Resistance and Capacitance measuring.
• Relative value measuring (REL) function, effectively eliminate lead-wire resistance or interference signals.
• It’s uniquely equipped with all-range measuring stopwatch and 0.5 kHz~22kHz sine signal output.
• Auto identify with Diode test and Continuity test
• With function of auto power-off time setting and manually cancels auto power-off.
• White backlight, capable of setting auto timing extending which convenient for measuring readout under dim light testing condition.
• The LCD contrast is able to be set according to the testing condition
