4. If the resistance of the closed loop is measured, the two ends of the measured
resistance must be treated for discharge, otherwise if the voltage in the loop is greater than
0.6 V, the instrument will be mistaken for the voltage measurement and enter the voltage
measurement mode.
5. the resistance between the red and black meter pen is greater than 50 2, the meter
will automatically switch the range according to the actual resistance measurement value,
and then the measured value will be displayed in the LCD.
Note:
1, When measuring low resistance, in order to obtain accurate reading, you can first
record the meter pen short circuit value, subtract the meter in the measurement reading
The value of the pen in short circuit;
2, When measuring the on-line resistance, all the power supply of the circuit must be
turned off and all the capacitors are discharged to ensure the accuracy of the measured
value.

1. Press the power key for more than 2 seconds to turn on the meter. boot display as
automatic scan state "AUTO", press power key to manually select diode measurement
function.

3. meter will show the positive pressure drop of the measured diode on the LCD. If the
polarity of the two ends of the diode in contact with the pen is reversed or the diode is open,
the LCD of the meter will show “OL"."
5-4, capacitance measurements
1. Press the power key for more than 2 seconds to turn on the meter. , boot display as
automatic scan state "AUTO", press power key manually switch to capacitance measurement
function.
2. Insert black watch pen into "COM" jack, red watch pen insert” V/ ©" jack, test watch
pen reliable contact test point.
3. Meter will automatically switch the range according to the capacitance value
between the red and black meters, and the specific value of the measured capacitance will
be displayed on the LCD. The measuring range of the capacitance is 10
nF/100nF/1uF/10uF/100uF/1mF/10mF/60mF..
Note:
1. Please treat the measured capacitance to discharge fully before measuring the
Capacitance, otherwise it will enter the voltage measurement mode.
