Power Supply Function

• When connecting the DUT (battery/capacitor), do not short-circuit

the battery/capacitor.

• When connecting the DUT (battery/capacitor), it is recommended

that you purchase the IT-E165A anti-reverse connection and anti-

spark module to prevent the battery/capacitor reverse connection

that may cause damage to the instrument and spark during the bat-

tery/capacitor wiring; When there is no external auxiliary equipment

connected to prevent reverse connection and anti-spark function,

please pay attention to the safety of the wiring, and be careful not

to reverse the battery/capacitor connection, reverse connection will

cause damage to the instrument.

• Before performing the battery test, you need to connect the Sense

cables to both ends of the battery. If the Sense cables are not con-

nected, the instrument cannot detect the Sense voltage and prompt

“Wait Power Link”, which will prevent the battery test from

continuing.
