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

2.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 obtained.
●
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 it.
3.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 measurement.
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 resistance.
● 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
measurement.
● The test leads and the Meter inside wire will
bring around 0.1Ω～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.
