7. Battery compartment

8 Test clips

4、 Usage:

1.After installing the battery in the correct way, connect the yellow, green, and red input terminals of the instrument to the three-phase power test terminal reliably.

A. When there is no input or less than 40V, LCDNo display：

B. When there is a phase loss in the three-phase electricity being tested, the LCD display is as shown in the following figure:

C. When the tested three-phase electricity is in phase, the LCD display is as shown in the following figure:

D. When the measured three-phase electricity is in reverse phase, the LCD display is as shown in the following figure:

2. Firstly, please observe whether there is a low voltage indicator symbol on the LCD display screen. If so, it indicates that the battery voltage has dropped below the normal value, which will affect the functionality and measurement accuracy of the instrument. Sometimes, a low battery voltage may cause the instrument to fail to turn on. In this case, the battery should be replaced in a timely manner.

3.After using the instrument, please disconnect the input terminal from the test point in a timely manner.

5、 Attention:

1.It is strictly prohibited to replace the battery or disassemble the instrument during the measurement process.

2.When the following situations occur, the instrument should be stopped and checked and repaired before use.

A.The appearance of the instrument is significantly damaged

B.The instrument cannot complete specific measurement operations

C.The instrument remains idle for a long time under improper conditions

D.The instrument was severely compressed during transportation

E. The instrument is damp or immersed in water

3.When the input terminal of the instrument is connected to the tested terminal,LCDWhen the phase is missing or all phase indicator lights are not on, it does not mean that there is no voltage in the measured circuit of the instrument. Please use the instrument to confirm before operating to avoid danger!

4.When the low voltage indicator symbol appears on the instrument, it is necessary to replace the battery of the same specification in a timely manner. When installing the battery, the input terminal of the instrument must be disconnected from the measured circuit to avoid electric shock! When the instrument is not used for a long time, the battery should be removed to prevent battery leakage and damage to the instrument.

　5.This instrument is a precision measuring instrument. To extend its service life, it should be avoided from being used in corrosive environments such as strong acids and alkalis, as well as high temperatures and humidity, to avoid damage to the instrument.

6.To ensure accurate measurement, please do not adjust or change the internal circuit of the instrument by yourself to avoid danger!

7.If the instrument accidentally gets water or liquid, it must be dried before continuing to use.

8.The use of the instrument cannot exceed the time limit for continuous operation of the instrument:

When the input voltage of two or three phases is220VThe continuous operation time shall not exceed60Minutes, enter400VContinuous operation time

not exceed4minute

9.This instrument must be used by professionally trained personnel and operated strictly in accordance with the user manual.
