Select the range first, look at the specifications of the leakage action current, no more than 100mA, an adjustable switch behind the M9000, adjust the value to 100, and then increase it accordingly. Then the red watch pen is connected to the lower mouth of any phase line, the black watch pen is connected to the zero line of the upper mouth, rotate the knob of the front current regulation, until the leakage trips, there is a small detail here, the action current of 30mA can generally be rotated faster in front of the first 15mA, and the 30mA of 50mA are rotated casually, and so on, generally will not jump, and the back will slowly rotate.
After jumping, the displayed value is the action current, the unit is ms, and then the other buttons do not move, and there is no need to reset the current knob, directly press the front ms button, and then close, and then press the analog button, the brake jumps again, and the displayed value is the action time, the unit is ms

The switch is energized, and the two gauge pens of the tester, one gauge pen are connected to the upper end of the switch and one is connected to the lower end of the switch, (note that it cannot be in phase). Then hit the gear to *1 gear. Press the test button to test. After the switch trips, the action time of the switch is displayed.

Press the "MS" direct key switch; Turn the (mA) adjustment knob to the panel scale to measure the current value. (According to the size of the setting action current value, match the range position of the transfer switch on the rear cover plate with the range value on the panel), and turn on the power switch.
Press the wiring diagram to connect the wire.
Close the switch of the leakage protector to be tested.
Press the "Analog" (electric shock) button and the breaking time value will be displayed on the display. The unit is milliseconds (ms), and the value is temporarily stored for a few seconds and then automatically reset to zero.
If you need to retest, just repeat , .
After testing, the test line is detached from the AC circuit in time; Turn off the power switch; Turn the (ma) adjustment knob counterclockwise all the way through; Straight key switch reset; The range transfer switch is pushed to the 100mA end.

The new leakage protector tester M9000 is extremely versatile
A Zen chaos, overview.
M9000 leakage protector tester can measure the action current and breaking time of leakage protector; Communication can also be measured.
voltage, line and equipment leakage current, etc. M9000 tester is a 90-year Zhejiang electric power science and technology project, the product standard refers to GB6829-86 and other relevant standards, and has been approved by the provincial level for the record, numbering Q33N23 453-90.
This instrument uses integrated circuits, which are small in size, multi-functional, high in accuracy, high in performance, easy to carry and use, and can be.
Test various types of leakage protectors. The test results are displayed digitally, intuitively, with high resolution, and the operation only takes a few seconds when measuring the operating current and breaking time of the leakage protector, and the display results are automatically temporarily stored for a few seconds and then automatically reset to zero, which is extremely convenient to operate.
This instrument measures a wide range of AC voltages and can be adapted to any low voltage system.
This instrument can detect the leakage current of the line and the total leakage current of the electrical equipment in the working position. It is convenient when it comes to leakage current detection.
Safe and reliable, with overcurrent protection.
The M9000 tester does not need to be connected to a separate power supply, and can work continuously for more than 200 hours with only a 9V tandem battery. Ceremony.
It comes with a packing and work bag that can be carried around for testing.
M9000 tester can be widely used in power supply department, agricultural power department, leakage protector manufacturer, construction, mining, etc
The labor security inspection department of the machine tool and other industries, as well as the majority of electricians, congratulated the harassment.
