Step 3 - Power Up
You can power up the N7040A/41A/42A probes by using:
•
External DC power supply - The DC voltage must be 12V (±10%).
• Batteries - Four standard 1.5V alkaline AA batteries provided with the probe.
When operating with the external power supply adapter, refer to Table 2, “External DC Power Supply
Characteristics,”
Replacing Batteries
The Status Indicator LED adjacent to the Power button on the probe glows Red indicating low
battery. To replace the battery, switch off the probe, remove the battery cover, and replace with
standard AA alkaline batteries.
CAUTION
Before applying power, ensure that all connections to the probe have been
made. Also, verify that all safety precautions have been taken.
CAUTION
The external power supply adapter (Keysight part number - 0950-5831)
provided with the probe must be used.
NOTE
When the external DC supply is present, the batteries are inoperative and
the external DC voltage powers the probe.
NOTE
It is recommended that the circuit under test is de-energised or the probe is
removed from the test circuit before replacing the batteries.
