Warning:

1. Selecting the correct terminal input and turns the rotary switch to select the measuring function. If fails to do that, the buzzer beep and the warning signal flash

• DC or AC Voltage Measurement
• To avoid harms to you or damages to the Meter from electric shock, please do not attempt to measure voltages higher than 1000 V although reading may be
• T h e M e t e r h a s a n i n p u t i m p e d a n c e o f 10MΩ(exceptUT802/ACV input impedance of 2MΩ) This loading effect can cause measurement errors in high impedance circuits and so you need to take a note on
• DC or AC Current Measurement
• Before connect the Meter in serial with the tested return circuit, closed the return circuit current to avoid the dangerous of sparking.
• Do not use over >10A current Although the meter can work on below 20A current testing but for the avoiding any harms to you or damages to the Meter.

4. Measuring Resistance, Diodes, Continuity or Capacitance

• To maintain the measurement accuracy, discount circuit power and discharge all the high voltage capacitors during the measuring

• When measuring high resistance on 1MΩ or above, it is normal to take several seconds to obtain a stable reading. In order to obtain stable reading, choose shorter test lead to carrying out

• The test leads and the Meter inside wire will bring around 1Ω～0.2Ω of error to resistance measurement when measuring low resistance. To obtain accurate readings in low-resistance, short
  circuit the test leads beforehand and record the reading obtained, call this reading as X.   Then use the equation: measured resistance value (Y) – (X) = accurate readings of resistance.

• During measurement, Diodes is in a good silicon junction drops between 500mV～800mV as the normal value. The continuity measurement, the poles between resistance is >100Ω. it is a short circuit, but on the poles between resistance is ≤10Ω, it is a good connection, buzzer is continually beep on, and the reading value is nearly to the circuit resistance value, Unit is Ω.
