Operating safely with battery power
For safe operation, the instrument chassis should always remain at earth ground potential.
Warning: To avoid electric shock, connect the side ground lug external chassis ground point to earth ground when operating the
instrument from battery power.
Without a connection between the chassis and earth ground, you can receive a shock from exposed metal on the chassis if you connect
an input to a hazardous voltage (>30 V
grounding cable from the ground lug terminal on the side panel to earth ground. If you use a different grounding wire, it must be at least 12
gauge.
If you choose not to attach the grounding cable, you are not protected against electric shock if you connect the oscilloscope to a hazardous
voltage. You can still use the oscilloscope if you do not connect a signal greater than 30 V
center, or the common lead. Ensure that all probe common leads are connected to the same voltage.
Warning: Hazardous voltages may exist in unexpected places due to faulty circuitry in the device under test.
CAUTION: When operating the instrument on battery power do not connect a grounded device, such as a printer or computer, to
the oscilloscope unless the instrument grounding cable is connected to the earth ground.
