Preparing Your Multimeter
Checking the shipment
When you receive your multimeter, check the shipment 
according to the following procedure.
1 Inspect the shipping container for damage. Signs of 
damage may include a dented or torn shipping container 
or cushioning material that indicates signs of unusual 
stress or compacting. Save the packaging material in case 
the multimeter needs to be returned.
2 Carefully remove the contents from the shipping 
container, and verify that the standard accessories and 
your ordered options are included in the shipment 
according to the standard shipped items list found in the 
printed copy of the U1231A/U1232A/U1233A Quick Start 
Guide.
3 For any question or problems, refer to the Keysight 
contact numbers on the back of this manual.
Installing the batteries
Your multimeter is powered by four 1.5 V AAA alkaline 
batteries (included with the shipment). When you receive 
your multimeter, the AAA alkaline batteries are not 
installed.
Use the following procedure to install the batteries.
Before you proceed with the batteries installation, remove all cable 
connections to the terminals and ensure that the rotary switch is at the 
OFF position. Use only the battery type specified in the “Product 
Characteristics” on page 102.
