When making measurements in high-energy circuits, use test leads that meet the following
requirements:
• Test leads should be fully insulated.
• Only use test leads that can be connected to the circuit (for example, alligator clips and spade
lugs) for hands-off measurements.
• Do not use test leads that decrease voltage spacing. These diminish arc protection and create a
hazardous condition.
Power circuit test procedure
Use the following procedure when testing power circuits:
1. Turn off power to the circuit using the regular installed connect-disconnect device. For example,
remove the device's power cord or turn off the power switch.
2. Attach the test leads to the circuit under test. Use appropriate safety-rated test leads for this
application. If over 42 V, use double-insulated test leads or add an additional insulation barrier for
the operator.
3. Set the Model DMM7510 to the proper function and range.
4. Power the circuit using the installed connect-disconnect device, and make measurements without
disconnecting the multimeter.
5. Remove power from the circuit using the installed connect-disconnect device.
6. Disconnect the test leads from the circuit under test.
DC voltage measurements
This section describes how you can set up DC voltage measurements from the front panel.
Inputs: Do not apply more than 1000 V
peak
between INPUT HI and LO. Failure to observe this
caution may result in instrument damage.
