4 PA30B digital three-phase leakage current tester (passive) Safety precautions
Four point one Before using please read the instructions and follow the instructions step in operation.
Four point two Do not use non original accessories, in order to avoid danger.
Four point three In order to ensure the accuracy of measurement, the test leads should be as short as possible.
Four point four The grounding end of the instrument must be in good contact with the earth.
Four point five The operator must be familiar with equipment operating procedures, can be used.
Four point six The operation of Taiwan necessary insulating rubber laying around.
Four point seven Continuous testing shall not be arbitrarily placed, when not in use shall not be connected with the instrument cabinet and the earth, to prevent the misuse of the test of broken instruments.
Four point eight The measurement must be carefully check whether the wiring is correct, to determine the correct, can be tested.
Four point nine After pressing the "start" button, the instrument shall not adjust the test line and the measured object.
Four point one zero If there is abnormal test instrument, can press the "reset" button or shutdown to suspend the test of instrument, to restore after the start test.
Four point one one In order to ensure the stability of the test voltage, AC power supply and use recommendations to match the output power leakage.
Four point one two The maximum output current as the transformer capacity and exceed this value will cause permanent damage to the instrument.
Four point one three Avoid using in the following circumstances:
A Avoid placing the direct sunlight and rain or wet;
B Please stay away from fire and heat, to prevent the high temperature of the machine;
C Handling or maintenance, should be shut down and will remove the power line.
5 PA30B digital three-phase leakage current tester (passive) Use and operation
Five point one The initial state
The power supply is switched on, the "power" on the "open" position, the power indicator light, display as "voltage" 000V "Current" display. 00.00mA , "time" display 000S . The lights out, the instrument is in the initial state.
Five point two Function setting
Three phase measuring set:
The test set for phase selection, start time setting can be set 0~999s, The commutation time setting can be set 1~5s . Connection method for A (rear), B and C and N Phase.
The three-phase continuous phase measuring set:
The test set for phase selection, start time setting can be set 0~999s, The commutation time is set to Zero . Connection method for A , B and C and N Phase.
Single phase measuring set:
The test set for phase selection, start time setting can be set 0~999s, No commutation time setting. Connection method for C and N Phase.
5.2.1 The test set
The test phase selection set
In the "initial state" press "set" button, "measuring the voltage" window "character, the leakage current" window character or "set" button, rotating, to do three test selection, test A (panel indicator), B and C Phase. To do the single-phase test selection, test N and L Phase.
The current alarm set
In the function test phase selection "press" set "button, or power on the" initial state "two press" set "button," measuring the voltage "window" character, the leakage current of "window value," set "button, the rotation can change the alarm value.
Start time setting
The function of "the current alarm setting state" press "set" button, or power on the "initial state" three press "set" button, "measuring the voltage" window "time window" character, numerical, rotating "set" button, can change the start time value.
Commutation time setting
Set the state "press" set "button in the" startup time or power on the "initial state" four press "set" button, "measuring the voltage" window "time window" character, numerical, rotating "set" button, can change the commutation time value. The maximum value for the commutation time 5S . Such as the choice of single phase test, the state will not appear.
Enter the start test
Set the state "press" set "button in the" startup time, or in the "commutation time setting" press "set" button, enter the test status.
