Preparing to Connect the DUT (Battery)
Constructing sensing cables
1
Using AWG 24 to 20 (0.20 mm
2
to 0.52 mm
2
) cables, construct the following
cable assembly.
2
Solder the thermistor lead to the tip of the temperature sensing cable.
As a guideline, keep the soldering time for the included thermistor less than 7
seconds at no less than 5 mm from the lead root when the soldering iron (50 W)
temperature is 340 °C.
The thermistor does not have polarities.
Be sure to insulate the thermistor lead area with heat-shrinkable insulation tube or the
like.
Pin no. Symbol Description
1 +S Positive voltage terminal. Connect to the positive terminal of the DUT (battery).
2 –S Negative voltage terminal. Connect to the negative terminal of the DUT (battery).
3 +T Temperature measurement terminal. Connect the included thermistor.
4 –T Temperature measurement terminal. Connect the included thermistor.
5 FG
Shield grounding terminal. This is connected to the PFX2512 chassis. Do not
connect the shield electric potential anywhere on the DUT (battery).

Sensing cable
(2-core shielded cable)
Use this screw to fix the
cables in place so that they
do not come loose.
Remove the first 7 mm of the wire’s covering, and then insert the wire here.
