Inspection and Installation
Copyright© Itech Electronics Co., Ltd. 2
Either for plane contacts or relay terminals that are not easy to clamp or small
objects like connectors, you just need to touch the test lines against the DUT for
four-terminal measurement. The meter pen can be directly unscrewed for
changing For detailed length specification, see the figure above.
The central probe of the meter pen is Sense and the outer cylinder probe is
Source terminal. The schematic diagram is as shown below.
IT-E602 Large clip type lead for small component test (Under DC600V)
It can be used to clamp thick cylinder parts of DUT and is easy for operation. To
take four-terminal measurement, directly clamp the DUT terminals. For detailed
length specification, see the figure above.

Before connecting the power cord, please ensure the power switch of the
instrument is turned OFF. Only use the power cord supplied as a standard
accessory. The range of working votage isAC100V~AC240V.
A summary of connection procedures is given below.
Select from the flowing Schedule of Power Cord Specifications an appropriate
power cord that matches the voltage for the area in which you use the
instrument. If the power cord included in the instrument you purchased does
not match the voltage, contact the dealer or manufacturer for change.

To avoid burning out, be sure to confirm that power voltage matches
with supply voltage.
To avoid electrical shock, before testing, please make sure the
ratingvalues of the testing lines, and do not measure the voltage that
higher than the rating value.
To avoid battery short circuit, be sure to check that the test line end is
not connected when connecting or disassembling the test line. When
the test line end is connected with battery, short circuit may cause
severe accident.
