2-6 Operating Procedure PFX2000
Attaching the thermistor (Fig. 2-4)
• Solder the thermistor lead to the tip of the temperature sensing wire.
As a guideline, the time for soldering the thermistor included in the package
should be less than 7 seconds at the position at least 5 mm away from the root of
the lead using a soldering iron (50 W) at 340
°
C.
• There is no polarity on the thermistor.
• Be sure to insulate the thermistor lead such as by using an heat-shrinkable tubing.
Fig. 2-4 Thermistor Attachment
You can use thermistors other than the ones provided (103AT-2 by Ishizuka Elec-
tronics Corp.) as long as they are equivalent. For the speci
fi cations of the thermistor
included in the package, see “Temperature Measurement” in chapter 5, “Speci fi ca-
tions.”
Connecting the output cables
Connect the output connectors of the unit frame to the DUTs using the output cables
you constructed.
•
Connection to the output connectors must be performed in the STANDBY
status or with the power switch turned off.
• Fix the output connectors in place by fastening the top and bottom screws.
• Do not leave the DUT (battery) connected for a long time with the power
switch turned off. The DUT may discharge minute current. (This is not a
problem in STANDBY status.)
• In a system in which the PFX2331 and PFX2332 unit frames are mixed,
connect the output cable assembled with the HC type connector to the
PFX2332.
• Keep the output cable as short as possible. Tying the cable in bundles or entan-
gling the cable can cause unstable operation of the product. Be sure to use the
optimum length of cable especially for pulse operation, because it is prone to
instability.
• Avoid attaching cores and fi lters on the output cable. The operation of the power
supply unit may become unstable.
