1. When using an external power supply, you only need to wire it as shown above.
2. Turn on the machine and select the external power supply on the initial interface.
3. Set the frequency so that the frequency is equal to the frequency of the external power
supply.
4. Click the test external power button, and the screen displays the size of the external
current. Adjust the external variable frequency power supply according to the size of this
current to make the current meet the requirements of the test. Return to the initial
interface.
5. Click the Start Instrument Test button to start the test.
6. All test methods of external power supply are exactly the same as internal power
supply test. I will not repeat them here.
X.Measure ground continuity
C1/P1 is connected to a grounding device, C2/P2 (measurement grounding terminal) is
connected to another grounding device.
note:
1. Do not coil the lead wire.
2. Keep voltage wires away from current wires as much as possible.
3. Both sides of the grounding clamp should be pressed tightly to prevent poor contact
caused by paint corrosion.
4. To prevent current protection, select a current of 2A.
Select ground grid frequency conversion 2A
