Troubleshooting Remote Communication and Battery Issues in Fluke DSP 2000 Network Cards

Getting Started 2

Remote Communication Error

Remote Communication Error

If you are running the NEXT@REMOTE or RL@REMOTE test, and the main unit detects a communication problem with the remote, the following message appears on the main unit: REMOTE communication error. This message means that the REMOTE data cannot be transmitted to the main unit, usually because the cable is defective. To verify proper remote operation, run a self-test as described in the earlier section “Performing a Self-Test.”

Battery Status

The test tool displays a message when its battery voltage or the remote battery voltage is low. Table 2-7 shows the battery status messages and what you should do if a battery message appears.

Note

To ensure continued operation while charging the battery, always connect the ac adapter/charger when the message

WARNING RECHARGEABLE BATTERY VOLTAGE IS

LOW appears.

Table 2-7. Battery Status Messages

Message Displayed

WARNING RECHARGEABLE BATTERY VO LTAGE IS LOW.

What You Should Do

Connect the ac adapter/charger.

RECHARGEABLE BATTERY VOLTAGE IS TOO LOW TO OPERATE.

WARNING REMOTE BATTERY VOLTAGE IS LOW.

WARNING REMOTE BATTERY VOLTAGE IS TOO LOW TO OPERATE.

INTERNAL DATA STORAGE BATTERY VO LTAGE IS LOW.

Turn the test tool off and connect the ac adapter/charger. If the tool does not operate when you turn it on, turn it off again and allow the battery to charge for about 30 minutes.

For a standard remote, have a 9V alkaline battery available. For a smart remote or second main unit, connect the ac adapter/charger.

Replace the alkaline battery in standard remote. Charge the NiCad battery in a second main unit or smart remote.

Have the lithium battery replaced at a Fluke Service Center.
