Safety instruction

The design of digital storage waveform multimeter ET201 is in accordance with the safety standard of IEC 1010-1, CAT

Ⅲ-600V, the second category of excess voltage electrical measuring. pollution protect grade: 1st grade.

1. Please check if the housing being damaged or if any accessories lost before using. Crucially, please pay highly

attention to check the insulation of the test pen and connection line. Do not contact the metal part of the test pen during your

using.

2. Operation doesn't allow in below condition: High temperature, Moist, Rainy day, inflammable and explosive, or even

your instrument become wet.

3. It’s completely not permitted to exert overload current/voltage that the instrument can accept during your using.

4. Please do remember to remove the pin of the test pen from the testing point when you are trying to exchange the

measuring function, pull/insert the plug of the test pen or turn on/ shut off the instrument.

5. Please pay attention to the safety warning signal displayed on the instrument: when the input voltage exceeds

DC1000V/AC750V, the buzzer will make a long alarm sound; and it will beep for three times when the input over the safety

voltage (36VDC/25VAC) under the measuring range of DC1000V/AC750V.

6. Please do not organize voltage measuring job when the voltage-to-ground reach 500V which showing on the reference

input terminus "COM" of the instrument.

7. It will be extremely dangerous in mistaken operation of voltage measuring even though there is a 500V fuse installed in the

20A measuring range

8. The test pen is definitely not allowed to touch the two terminal of the voltage source when choosing below measuring

function: current, resistance, continuity, diode, capacitance and so on.

9. Before conducting the resistance and diode/continuity test, please cut off the power of the measurand and make sure the

capacitor of the power supply circuit has discharge completely.

10. The instrument power must be cut off and the test pen must be removed from the circuit before replacing for the fuse in

the backboard of the instrument. And the fuse specification should be kept in same accordingly.

11. Product and accessories should not be reconstructed, separated or taken into other usage beyond the original function

design; meanwhile, all of the accessories or enclosure can't be random replaced.

12. Please don't electricize for ordinary batteries, and please replace the batteries when low power prompted in the

screen.

Safety Symbol:

Dangerous! When this symbol marks beside other sign or lies near the socket terminal, it indicates that the

operator must obey the manual instrument for use.

Electric shock dangerous! When this symbol marks on one or more using terminals, it indicates that it may

carry dangerous voltage during using. To guarantee your safety as much as possible, please don't touch the

testing terminal of the test pen with your hand.

When this symbol lies near the connection terminal, it indicates that the Max acceptant current between the

terminal and the COM is 20A. "FUSE" means that there is a 20A internal fuse (250Ma) installed. And it's

strictly forbidden to measure the circuit current when the AC voltage is over 250V

Prompt!

The Prompt statement indicates that you should be careful because mistaken operation may lead to wrong testing

result or accessories damaged.

Attention!

The Attention statement indicates that you must be pretty careful because mistaken or disobeyed operation may

damage the product or possibly cause extra properties loss.

Warning!

The Warning statement indicates that you should be as much as concentrated because mistaken or disobeyed operation

may cause people injuries or even life danger.
