Parameter Setting
1. Setup of test time
1)
The preset conditions of test time:The tester must be in a reset state,that is the tester can’t be
in a state of test and alarm.
2) Preset method

Time increases:In the front faceplate has a UP button,click on this button,the time preset
value plus 1;if you hold this key,preset time continuous add 1,when added to a certain value,preset
time continuous add 10;until 999s.
2
Time decreases:In the front faceplate has a DOWN button,click on this button,the time
preset value minus 1;if you hold this key,preset time continuous minus 1,when reduced to a certain
value,preset time continuous minus 10;until 0.0s.
2. Preset of AC current alarm value
1) The preset condition of AC current alarm value is that the AC/DC key on the front panel is
opened, that is, the instrument is in the AC state. Note: only AC test instrument does not have
this step.
2) Methods: press the test / preset preset button, the current display window shows the current
preset value; use the debug screwdriver clockwise adjust current preset potentiometer, the
preset current increases; counterclockwise regulating preset current decreases; the alarm current
value preset to the required test value, pop test / preset button.
3. Presetting of DC current alarm value(Single AC withstand voltage tester without this
function)
1) The preset condition of AC current alarm is to press the AC/DC button on the front panel, that
is, the instrument is in the DC state.
2) Methods: press the test / preset preset button, the current display window shows the current
preset value; use the debug screwdriver clockwise adjust current preset potentiometer, the
