Computerized Battery Analyzer
Temperature Probe
Plug the probe’s two-pin connector in to the right hand two pins (closest to the LEDs) of the three available
pins in the cover slot. It does NOT make any difference which way it goes in as long as it is plugged in to
the far right two pins. The extra pins are for future options. Do NOT remove the blue jumper.
Let the probe sit in a location away from any heat source for enough time to allow it to acclimate to room
temperature. Have a good thermometer near by, if you wish, for more accurate calibration. If you do not
have a good thermometer handy set it to any room temperature reference. For laboratory quality
measurements you may wish to calibrate it near the temperature of interest by submersing the probe in hot
water along with a high accuracy thermometer.
With a temperature probe connected to the CBA, go to "Edit", "Calibrate Temperature Probe" and in either
deg C, or F, type in your reference temperature reading and push OK. Note: As long as you do not change
to a different CBA or temperature probe you should not have to calibrate the probe again.
lso note that this
option will be grayed out if the probe is not connected.
To use the probe, attach it in close physical contact with the center of the battery, or battery pack that you
are testing. Hold it in place with the probe’s magnet (most round cells are magnetic), or with tape or a
rubber band. Be certain it stays in close contact with the battery during your test. The CBA temperature
readings are quite accurate over the range that a battery may be operated at, however the readings will be
incorrect if the probe is not in close contact with the battery or there is air moving over it. Unlike an instant
response IR thermometer other types of thermometers take a considerable amount of time to display their
temperature reading. There is a noticeable thermal lag with our thermistor type probe.
The CBA may be set for automatic over temperature cutoff. Place the probe on the battery. Go to “Edit”
“Preferences” and check the check box next to “Stop test when battery reaches ? deg”. The default cutoff is
140 deg. F or 60 deg C which should be safe for most battery types, be careful if you choose a higher
temperature cutoff.
WARNING: DO NOT
continue a test if the "Temp:" indication reaches or exceeds the maximum temperature
specification for the battery being tested.
