Battery replacement
WARNING
Disconnect the instrument from the power line and all other equipment
before changing the battery.
The volatile memories of the Model 2410 are protected by a replaceable battery when power
is off. Typical life for the battery is approximately ten years, but the battery should be replaced
if the voltage drops below 2.5V regardless of age. The battery should be suspected if the
instrument no longer retains buffer data or user-defined operating parameters, such as
instrument set-ups, source memory, and math expressions. If the battery is absent or totally
exhausted, the display will show the “Reading buffer data lost” message shortly after the
Model 2410 is switched on.
The battery is a 3V wafer-type lithium cell (
Panasonic BR-2330-1VC
), which is located on
the digital board. Replacement of the battery requires removal of the case cover and analog
board assembly. (See Section 5.) Use only the recommended battery.
NOTE
Calibration constants and user-defined parameters will be lost when the battery is
replaced. The Model 2410 must be re-calibrated (Section 2) after the battery is
replaced.
WARNING
The precautions below must be followed to avoid personal injury.
1. Wear safety glasses or goggles when working with lithium batteries.
2. Do not short the battery terminals together.
3. Keep lithium batteries away from all liquids.
4. Do not attempt to recharge lithium batteries.
5. Observe proper polarity when installing the battery.
6. Do not incinerate or otherwise expose the battery to excessive heat (>60°C).
7. Bulk quantities of lithium batteries should be disposed of as a hazardous waste.
To replace the battery, carefully unsolder it, and then solder the new one in its place.
Re-assemble the instrument and turn it on. The “Reading buffer data lost” error message will
be displayed. Send the :SYST:MEM:INIT command to perform the following:
•
Clear the reading buffer.
•
Initialize instrument setups 1
to
4 to the present instrument settings.
•
Initialize all 100 source memory locations to the present instrument settings.
•
Delete user math expressions.
