Measure Temperature - Fluke BT21ANG User Manual

Measure Temperature

The black extenders (long and short) of the BTL21 Interactive Test Probe each has an
IR temperature sensor. The IR temperature sensors can measure the temperature of
battery poles (negative pole).
To measure the temperature of a battery pole:
1. Aim the IR sensor on the battery pole.
2. Adjust the test lead to let the entire flare fall on the battery pole. See Figure 4-5.
The temperature reading shows on the LCD of the interactive test probe.
3. Push the Save key on the interactive test probe.
The temperature reading is saved in the Product memory. The reading can only be
accessed through a PC.
Figure 4-5 shows the measurement field of a battery pole.
