ET 8133 USER MANUAL
1.Overview
This product is a true RMS 2000 counts display automatic range digital multimeter .
2.Safety instructions
To avoid possible electric shock, fire, and personal injury, please read the safety precautions
before using. Please use the product only for the specified purpose, other applications will
weaken the protective device and cause danger.
Please check the shell / cracks and insulation near the input port carefully before using the
product..
Do not use this product in the atmosphere of explosive gas and algal gas or in humid
environment.
If the dc voltage is over than 36V or ac voltage
is over than 25V, the voltage will cause serious injury to the
body. Users should be attention to avoid touching.
When the measured parameters exceed the power range of the instrument. The display will
show "OL"
Please replace the battery when Low battery charge may affect accuracy of test results. Do n
ot use this product when back cover of the battery is not closed properly.
3.Function keys

4.Measuring DC/AC Voltage
Only when the measured voltage is higher than 0.8V, this product will display the reading.
Insert the red test lead into the right jack, the black test lead into the COM jack.
AC/DC voltage can be identified automatically.
Contact the correct test point on the circuit with the test lead probe.
Read the voltage shown on the display screen.
5.Measuring the Resistance
This product can automatically identify resistance measurement.
Insert the red test lead into the right jack, the black test lead into the COM jack.
Contact the desired circuit test point with the meter probe.
Read the resistance values measured on the display.
6.Continuity test
This product can automatically identify the Continuity test.
Insert the red test lead into the right jack, the black test lead into the COM jack.
Connect the meter probe to the two points of the circuit to be tested.
Resistance to be tested<50 Ω,the buzzer will sound and the indication light will light on.
7.Non-contact Voltage detection
Press NCV button and hold it to enter NCV mode.
Please place the meter close to the test field, the stronger the electromagnetic field , faster
beep will beep and indicator light will flash.
Touch this button,the product will hold the current reading on the LCD
screen.
Please hold the button to enter NCV mode and to testing. leave this button t
he exit the NCV mode. NCV function is inactive when it’s in electric current t
esting.
Touch this button to light up, and then touch it again to close.

8.Measure the current
Insert the meter test lead into the current channel, the product will automatically switch to
the current measurement mode, which can automatically identify the AC/DC current.
Insert the red test lead into the left mA jack and the black test lead into the COM jack.
Connect the meter probe to the two points of the circuit to be tested.
Read the current value measured on the display.
The measurement time should be less than 3 seconds when the current is higher than 200
mA.
The product will continue to alarm every four seconds remind to avoid the wrong operation
of without any measurement when the meter test lead is inserted into the current jack.
