The use and operation of the 4PZ93 type residual voltage tester
3.1 feature set
The power switch on 4.1.1 instrument, open the "power" switch, the power supply voltage for the display window display 000V Show window display for the residual voltage. 000.0V The number of measurements, display window display 00 Second, all lights are in the off state, the instrument is in the initial state.
4.1.2 set the number of measurements
In the initial state according to a set of keys, set light, power supply voltage window display Cou The number of measurements, set the window display 00 Then, in descending button, add key, set the range One ~ Ninety-nine After the end of time, setting, then press the set key into the tested equipment power supply time setting.
4.1.3 tested equipment power supply time set
The power supply voltage window display Sup The residual voltage, window display 000 Then, in descending button, add key, set the range One ~ 999s Press set key, enter the measurement time setting.
4.1.4 set off time
The power supply voltage window display Tes The residual voltage, window display 000 Then, in descending button, add key, set the range One ~ 999s Press set key, enter the alarm set value voltage.
4.1.5 alarm set value voltage
The power supply voltage window display Alt The residual voltage, window display 0000 Then, in descending button, add key, set the range 1.0V ~ 100.0V Then, after setting, press set key end set.
4.2 testing steps
The apparatus is placed in the initial state of 4.2.1 will be set up.
The measuring end socket plug 4.2.2 of the measured object is inserted into the instrument on the back plate.
Press the key 4.2.3 measuring instrument, the instrument started to test analyte specific test process is as follows:
The measured power supply equipment NS ( N by One ~ 999s )
The measured power equipment MS ( M by One ~ 999s ) , At the same time test N end L End voltage. N , L Light
The measured power supply equipment NS ( N by One ~ 999s )
The measured power equipment MS ( M by One ~ 999s ) , At the same time test N end G End voltage. N , G Light
The measured power supply equipment NS ( N by One ~ 999s )
The measured power equipment MS ( M by One ~ 999s ) , At the same time test G end L End voltage . . G , L Light
Note: the 4 5 6 after the completion of said completed a survey. And the number of measurements minus one.
Note: the measured equipment power, residual voltage window shows the current test voltage value, and after a power failure One Seconds,
Take this as the residual voltage of voltage. (please see IEC60335-1-2006 No. Twenty-two point five Relevant provisions)
Note: in the measuring equipment of the power supply, the residual voltage window display value is the maximum value of all residual voltage.
The repetition of the 4 5 6, until the number of measurements for Zero The number of measurements (i.e. display window display" 00 "), the residual voltage at the measured value is below the alarm buzzer short beep indicates the end; such as the maximum residual voltage measured value is higher than the alarm buzzer ringing the alarm lights. The end of the test state after the residual voltage window shows the maximum residual voltage. Only press the reset button to return to the initial state.

6.1 AC voltage test
According to "3", then press "set" button to enter the AC voltage calibration standard table on the back plate measuring end join, screw the pressure regulator to test AC voltage. After verification, the counterclockwise twist regulator to zero, and click 'reset' button to exit.
6.2 DC voltage test
According to the "print", then press "set" button to enter the DC voltage to test the DC signal to the rear end of the DC voltage can be measured, verification. After verification, click 'reset' button to exit.
6.3 test time test
According to the requirements of the national standard sample in power: 1s After testing the residual voltage. Below is the measurement 1s The method.
7 note
The instrument adopts the voltage regulator with larger capacity, while closing will produce impulse current. If the air switch capacity is small, the instrument will work in the air switch trip.
