Conditions for ensuring long-time trouble-free working
Due to the dimension, weight, and actual use of the instrument, the voltage generation module of the
instrument has a small heat dissipation design. Therefore, the instrument is recommended for use in
the following ranges. If the fan has been in continuous operation for 30 minutes, the instrument must
be suspended; otherwise the amplifier output module may burn out due to overheating.

Daily inspection
In order to avoid accidents, at least the following points must be guaranteed before using:
1.
The input power of the instrument is in compliance with the specifications, and the power supply
of the instrument is configured correctly.
2.
The instrument is reliably connected to the earth.
3.
The test cable material is intact, no cracks, split and breakage.
4.
The instrument is not connected to the test cable. The test is started under the default conditions
and the test can be completed successfully.
5.
When connecting the test line to start the test, the low voltage terminal of the test line is in contact
with the high voltage terminal of the test line, and the instrument can generate a FAIL signal.
