Page 5: Diode And Continuity Test
20MΩ ±(1.0%+25) 10kΩ Open voltage: less than 3V. Overload protection: 250V DC or AC peak value. NOTE: At 200Ω range, the test leads should be short-circuited, and measure the lead to lead resistance, then, subtract from the real measurement. It is normal for reading to be slow when measured value is above 1MΩ, please read it after the display value stabilizes. -

Range Displaying value Test condition The positive DC current is approx. Positive voltage drop of diode 1mA，negative voltage is approx. 3V Buzzer sounds , open voltage is approx. the resistance is less than(50±20)Ω Overload protection: 250V DC or AC peak value Warning: DO NOT input any voltage at this range for safety! 3 OPERATION 3.1 Front panel description... -
Page 7: Current Measurement
3.3 CURRENT MEASUREMENT 3.3.1 Insert the black test lead into “COM” jack, the red one to “mA” or “10A”jack. 3.3.2 Set the range knob to a proper DC or AC mA/A range, If the measured voltage is unsure beforehand, set the range knob to the highest range, then reduce it gradually until get the highest resolution readings. -
Page 8: Frequency Measurement
Before measuring, LCD display might not be zero, the residual reading will decrease gradually and should be disregarded. When measuring large capacitance, LCD may display an unstable value due to creepage or breaking. Discharge capacitors completely before capacitance measurement to avoid damage. Do not input any volt at this range. -
Page 9: Maintenance
After not working about 15minutes, the meter will be changed to sleep mode. Press “POWER APO” key for 2 seconds to restart the power. Press the “POWER APO” key for 2 seconds to cancel the function of auto power off and “APO” icon will disappear from LCD; press it again for 2 seconds to restart the auto power off function and “APO”... - Page 10 ●Replace fuse NO CURRENT INPUT ●Replace battery BIG ERROR PROKIT’S INDUSTRIES CO., LTD. http://www.prokits.com.tw E-mail:pk@mail.prokits.com.tw ©2014 Prokit’s Industries Co., LTD.
