Then subtract it from the real measurement. 2.5 Diode and continuity test Testing Range Display Condition Forward DCA is Forward approx. voltage drop of 1mA， diode Backward voltage is apporx.3V Buzzer makes a long sound Open while voltage is resistance is approx.3V less than (70±...
- Page 8 peak value 2.6 DC Voltage Measurement 1. Apply the black test lead to "COM" terminal and the red test lead to “V/Ω” terminal. 2. Set the knob to a proper DCV range, and connect the test leads crossly to the electric circuit under test.
- Page 9 3. Do not attempt to input voltage over 600V. Otherwise, it may damage the circuit of the meter. 4. Avoid touching high voltage circuit when measuring it. 2.7 AC Voltage Measurement 1. Apply the black test lead to "COM" terminal and the red test lead to “V/Ω” terminal.
- Page 10 is over range. Please set the knob to a higher range. 3. Do not attempt to input voltage over 600Vrms. Otherwise, it may damage the circuit of the meter. 4. Avoid touching high voltage circuit when measuring it. 2.8 DC Current Measurement 1.
- Page 11 highest range if users have no idea about the range of voltage under test. Then select the proper range based on display value. 2. If MSD displays “1", it means the meter is over range. Please set the knob to a higher range.
- Page 12 resistance under test. Note: 1. The LCD displays "1" when the resistance is over the selected range. The knob should be adjusted to a higher range. When resistance under test is over 1MΩ, the reading shall be stable in a few seconds, which is a normal status when measuring high resistance.
- Page 13 1. Apply the black test lead to "COM" terminal and the red lead to "V/Ω" terminal (the polarity of red lead is “+”) 2. Set the knob to range, connect test “ ” leads to the diode under test. The red test lead connects to diode positive polarity and the reading is the approx.
- Page 14 2. Do not measure voltage on range Ω. 3. Do not use this meter for measurement if the battery is not correctly placed or the back case is not properly screwed. 4. Remove the test leads from the testing points and turn off the meter before replacing battery or fuse.
- Page 15 2. Take out the battery and open the back cover. 3. Please use fuse of the same specification. The operation manual is subject to change without notice. The content of this manual is regarded as correct. In case readers find any errors and missing parts, please contact the manufacturer.
- Page 16 This product needs to connect high voltage for measurement, so please don't try to modify the circuit. Users who modify the circuit by themselves should take responsibility consequence caused. 601E-830L-000C...
