The Handler extension interface of transformer scanning. When the number of sorting signals
of the transformer scanning Handler interface is insufficient, this interface can be used to
expand the sorting signal and realize the sorting output of the transformer scanning result.
11) LCR HANDLER interface
The Handler interface can realize the sorting output of the test results. This interface is used for
the sorting of the single-group test of the bridge and the transformer.
12) RS232C serial interface
The serial communication interface can realize the online communication with the computer.

1) Nameplate
Indicate production date, instrument number, manufacturer and other information.
2) Fuse base
Being used to install power fuse, protect instrument, and switch 110V/220V by changing the
direction of core.
3) Power socket
Input AC power.
Warning: Before powering on, pay attention to whether your fuse position is consistent
with the supply voltage range.
4) TransScanner interface
To control the transformer scanning box through the Trans Scanner interface. It is compatible
with TH1901 and TH1831 scanning boxes, but different scanning boxes require different
connection cables.
5) Ground terminal
This terminal is connected to the chassis of the instrument. It can be used to protect or shield
ground connections.
