Users in the" N "And" L Direct access to "end with the power supply voltage test.
5.2.2 each phase measurement time setting
In the initial state, press "set" button, "test voltage" for display" TEST "," time "display the last set value, enter each phase measurement time setting. According to the "long" increasing key per phase measuring time value, in descending bond amounting to reduce the measuring time value of each phase. Setting range 1s~99s (including 0s Said measuring time is infinite, i.e. manual commutation measurement). Press "set" button to save each phase measurement time setting and into the next set state again ( The current alarm set ) . If press the "reset" button to cancel the next set, exit the setting, the instrument for the initial state.
5.2.3 manual / Automatic commutation mode selection
If every time is not set for phase measurement" Zero "When is the" automatic "commutation mode," automatic "indicator light, when to press the" measure "button" N Phase measurement, phase measurement after each time, automatically" L Phase measurement; if each phase measurement time is set to" Zero "When is the" manual "commutation mode," manual "indicator light, when press the" measure "button, can press the" phase change "button to change the phase measurement.
The current alarm set 5.2.4
In the initial state two press "set" button, "test voltage" display for" ALAr "," leakage "display the last set value, enter the current alarm setting state. According to the "long" increasing bond increased the current alarm set value, in descending
6 bond amounting to reduce the current alarm set value. Setting range 0~20.00mA . Press "set" button to save the current alarm set value and into the next set state again ( Address code setting ) . If press the "reset" button to cancel the next set, exit the setting, the instrument for the initial state.
5.2.5 address code setting (only for communication settings)
In the initial state, according to the three "set" button, "test voltage" for display" Addr "," time "to display the last address code setting, namely equipment into the address code setting state key" / "increased according to increasing address code value, in descending bond amounting to reduce the address code value, setting range 0~99 Again, press the "set" button, that holds the address code setting and into the next set of state ( Baud rate setting ) At this time, if you press the "reset" button to cancel the next set, exit the setting, the instrument for the initial state.
5.2.6 baud (only for communication settings)
In the initial state, according to the four "set" button, "test voltage" for display" BPS "," leakage current "display the last baud rate setting value, enter the baud rate setting state. According to the "long" to increase the baud rate increasing key value in decreasing bond amounting to reduce the baud rate, the set value is" 1200/2400/4800/9600 "Four files, press" set "button to save the baud rate setting value and complete set again, exit the setting, the instrument for the initial state.
5.3 testing steps
5.3.1 complete set, the instrument is in the initial state.
Seven
If the a object is a single-phase three plugs are not connected "measuring end I "Only the measured object is directly inserted into the instrument on the back plate
The measuring end of the socket.
If the B object is two plugs, in addition to the measured object is directly inserted into the instrument on the back plate of "measuring end II", and use the test line
The measured object protection grounding terminal and instrument on the back plate of "measuring end of" properly connected.
If the C does not use isolation transformer, the measured object must be insulated and open the earth (only for PA30A ).
Note: the "end of measurement" and "measuring end II" has been connected in the instrument.
5.3.3 status indication
When measuring, press the "measure" button, the instrument began tested, this "test N "Light instrument first on the measured object" N "Test" at the same time, the test voltage display shows the current voltage test, leakage current display leakage current, "" time "to display the remaining test time, such as the measured value of leakage current is greater than the set value, the alarm lights, after the test ended, the buzzer sends out alarm sound. At the same time" N "The lights, alarm lamp and the current value of the latch, no longer measuring instrument" L On the other hand, such as "phase; the measured leakage current is less than the set value, the test time after the end of" qualified "lights and the current value of the latch," N "After testing, automatic measuring instrument of commutation" L "(the content is based on the" automatic "indicator light in the case; such as the" manual "indicator light, need to finish" N "After, press the" phase change "button to start measuring" L "). When the two time after measurement showed the maximum value, such as qualified, instrument issued a short "beep" sound.
5.3.4 protection function
When the test voltage exceeds the 300.0V The display will show "voltage" test" ---- "Said overvoltage. The leakage current of more than 21.00mA The leakage current, the display will show "" ---- "Said the current. You should stop testing and instrument reset". When the test voltage exceeds 8" Three hundred and thirty " V The leakage current exceeds or" Twenty-two " MA Stop, automatic measuring instrument, enter the state of protection, the display flashes, waiting for the "reset".
