red one to
“V/Ω/Hz” terminal.

4. Connect the leads crossly to the electric circuit under
test; LCD displays polarity and voltage under test
connected by the red test lead.
Note
：
1. Firstly users should select the knob to the highest
range, if users had no idea about the range of voltage
under test, and then select the proper range based on
displaying value. If LCD
displays “OL”, it means meter is
over the max. Value of this range, thus should select the
knob to a higher range.
2. Do not input a voltage over DC 1000V.
3. Be carefully while measuring a high voltage. DO NOT
touch the high voltage circuit.
4.When the measuring voltage large than DC1000V
，
the built
–in buzzer will be sounds.

4. Connect the leads crossly to the electric circuit under
test, LCD displays voltage by the test lead.
Note:
1. Firstly users should select the knob to the highest
range, if users had no idea about the range of voltage
under test, and then select the proper range based on
displaying value. If LCD displays “OL”, it means meter is
over the max. Value of this range, thus should select the
knob to a higher range.
2. Do not input a voltage over AC 750V.
3. Be carefully while measuring a high voltage. DO NOT
touch the high voltage circuit.
4.When the measuring voltage large than AC750V
，
the
built
–in buzzer will be sounds.
4-4.DCA measuring
1.Insert the black test lead to “COM” terminal and the
red one to “mA” terminal (the Max. 600mA) or to
“20A”(the Max.20A);
2.Select the knob to a proper DCA range, press
“DC/AC” key to select the measurement mode, then
connect the leads crossly to the electric circuit under
test; LCD displays polarity and current under test
connected by the red test lead.
Note:
1.
Firstly users should select the knob to the highest
range, if users had no idea about the range of
current under test, and then select the proper range
based on displaying value .
2.
If the LCD displays “OL”
，
it means the current is
over range. Now you need to select the knob to the
higher.
3.
Max. input current is 600mA or 20A
（
subject to

, too large current
will damage the fuse.
4-5.ACA measuring
1.Insert the black test lead to
“COM” terminal and the
red one to “mA” terminal (the Max. 600mA) or to
“20A”(the Max.20A);
2. Select the knob to a proper ACA range, press
“DC/AC” key to select the measurement mode ,and
connect the leads crossly to the electric circuit under
test. LCD displays current by the test lead.
Note
：
1 Firstly users should select the knob to the highest
range, if users had no idea about the range of current
under test, and then select the proper range based on
displaying value .
2.
If the LCD displays “OL”
，
it means the current is over
range. Now you need to select the knob to the higher.
3.Max. input current is 600mAor 20A
（

, too large current will damage
the fuse.
4-6.Resistance measurement
1. Select the knob to a proper resistance range, and
connect the leads crossly with the resistor under tested.
2.insert the black lest lead to “COM” terminal and the
red one to “V/Ω/Hz” terminal
；
3.Auto range is the original states ,press “RANGE”key
